-# North Star
-
-The direction the loop aligns every increment to. Depth lives in
-[`internal/docs/THESIS.md`](../../internal/docs/THESIS.md); this is the short,
-operative version the planner and builder read each run.
-
-## Mission
-
-Make building an **agent** as easy as building a **service**, on one runtime.
-Go Micro is a holistic agent harness and service framework encapsulating the
-lifecycle of **services → agents → workflows** — pluggable, progressive, and
-AI-native by default.
-
-## Right now — developer adoption
-
-The framework's depth is strong; the **on-ramp** is the gap. Weight the developer
-experience — a walkable first-agent tutorial, discoverable examples, docs
-wayfinding, install friction, debugging, the 0→1 and 0→hero path — **at least as
-highly as internal hardening**. A developer succeeding on their first agent
-matters more right now than another conformance/observability/interop increment.
-Do not let the queue fill entirely with internal depth work.
-
-## Guardrails
-
-- One concern per PR; small and reversible.
-- The gate is green CI (`go build`, `go test`, `golangci-lint`, `make harness`),
-  not human review — keep the suite strong; the loop is only as good as its evaluator.
-- **Off-limits without a human** (surface as notes, never auto-merge): breaking
-  public-API changes, brand/positioning/marketing copy, new dependencies,
-  architectural rewrites, product-default changes with broad behavioral impact.
-- Stay on `claude/*` / `codex/*` branches; base PRs on `master`. See
-  [`CODEX.md`](../../CODEX.md) and [`internal/docs/CONTINUOUS_IMPROVEMENT.md`](../../internal/docs/CONTINUOUS_IMPROVEMENT.md).

-# Priorities
-
-The ranked work queue for the autonomous improvement loop. The
-**architecture-review** pass (the *architect*) owns this file: each run it turns
-the [roadmap](../../ROADMAP.md) plus an internal scan (gaps in the
-services → agents → workflows lifecycle, API coherence, drift, tech debt, test and
-DX friction) into a single ordered list — highest-value first — and links each
-item to a tracking issue. The hourly **continuous-improvement** pass works the
-**top item whose issue is still open**. So the architect decides *what*, and the
-increment loop *builds* it.
-
-**Reading / editing.** An item is done when its linked issue closes (the increment
-that builds it adds `Closes #<issue>`). Roadmap phase (Now → Next → Later) is the
-primary ordering; internal findings are interleaved by value, not kept in a
-separate list. The human can reorder this list — or the issues — at any time to
-redirect the loop; direction always wins.
-
-**Off-limits to the loop** (the architect proposes these as notes, never as queue
-items the loop can auto-merge): brand/positioning copy, breaking public-API
-changes, architectural rewrites. Those go to the human.
-
-## Work queue (ranked)
-
-1. **Fix atlascloud plan-delegate missing delegated notify side effect** ([#3805](https://github.com/micro/go-micro/issues/3805)) — the universe concierge notification gap closed in #3811, so the remaining top live-harness blocker is the delegated-plan variant: agents can create the expected work but still miss the observable notify side effect. Keep this first because it protects the adoption-critical 0→hero promise with a real side-effect assertion rather than a weakened text-only pass.
-2. **Isolate file-store tests from shared default directory** ([#3751](https://github.com/micro/go-micro/issues/3751)) — repeated `go test -race -cover ./...` failures still point at file-store reliability under the shared default directory/table setup. This remains the highest-value store/CI stability issue because a flaky evaluator erodes the loop's ability to ship adoption work safely.
-3. **Stabilize file-store suffix expiry test timing** ([#3780](https://github.com/micro/go-micro/issues/3780)) — the newer store failure is a narrower timing-sensitive suffix-expiry assertion under `-race -cover`. Keep it adjacent to #3751 but separate because it may need a focused TTL/assertion fix even if directory isolation improves the broader file-store tests.
-4. **Propagate agent run cancellation and deadlines through model and tool calls** ([#3544](https://github.com/micro/go-micro/issues/3544)) — once the live harness and red CI blockers are cleared, the highest-value remaining resilience gap is predictable failure semantics across agent runs, model calls, tool calls, plan/delegate, and flow handoffs. Tool retries, live-provider deadline tuning, delegated-plan completion, and side-effect enforcement are in place; the lifecycle still needs cancellation/deadline propagation so work fails safely instead of becoming opaque loops.
-5. **Emit OpenTelemetry spans for agent run timelines** ([#3525](https://github.com/micro/go-micro/issues/3525)) — recent work made runs inspectable, correlated trace metadata through scheduled dispatch, verified restart resume, added opt-in tool retries, hardened provider conformance, and fixed provider-emitted text tool calls. The next Next-phase step is to turn that RunInfo foundation into standard OTel spans for agent runs, model calls, tool calls, checkpoint/resume, cancellation/deadlines, and failures.
-6. **Add an AP2 mandate layer over A2A and x402** ([#3552](https://github.com/micro/go-micro/issues/3552)) — this is a forward interop investment, not a Now-phase blocker: Go Micro already has A2A agents and x402 paid tools, so a small signed-mandate foundation can keep agent payments aligned with the open-protocol story without pulling the queue away from adoption, resilience, or observability. Keep it additive and opt-in while the AP2/FIDO work settles.

-Run one continuous-improvement increment per `internal/docs/CONTINUOUS_IMPROVEMENT.md`, aligned to the North Star in `.github/loop/NORTH_STAR.md` (the services → agents → workflows lifecycle, with developer adoption as the current goal).
-
-PICK THE WORK FROM THE QUEUE: read `.github/loop/PRIORITIES.md` and take the highest-ranked item whose linked issue is still OPEN — that is your task, and its issue number is the one you close. If `PRIORITIES.md` is missing or every listed item's issue is already closed, fall back to the single highest-value roadmap / open-issue / improvement-radar item yourself.
-
-Implement it, and VERIFY `go build ./...`, `go test ./...`, and `golangci-lint run ./...`.
-
-Open the PR YOURSELF from the shell — do NOT use the make_pr tool (in this environment it only records metadata and never creates a PR). Create a uniquely-named branch under the `codex/` prefix: `git switch -c codex/increment-__ISSUE__`, then `git push -u origin codex/increment-__ISSUE__`, then `gh pr create --base master --label codex --title "<title>" --body "<body; include 'Closes #<the priority issue you built>' so it leaves the queue, and 'Closes #__ISSUE__' for this run's tracker>"`. Finally enable auto-merge so GitHub merges it once CI is green: `gh pr merge --squash --auto --delete-branch`.

-Act as DevRel for go-micro. Do these, in order.
-
-COHERENCE AUDIT. Audit the public surface — `README.md`, `internal/website/` (landing `index.html` + `docs/`), and the blog under `internal/website/blog/` — for coherence with the North Star in `.github/loop/NORTH_STAR.md` (an agent harness and service framework; the services → agents → workflows lifecycle). Look for: places where README / website / docs contradict each other, are stale, or describe behavior that has since changed (cross-check against the code and recently merged PRs); whether the README is crisp and leads with the harness positioning; and one to three genuinely blog-worthy items from recently shipped work.
-
-CHANGELOG UPKEEP (safe factual task — goes in the auto-merged PR). Keep `CHANGELOG.md` living, in Keep-a-Changelog format with newest content at the top under `## [Unreleased]`. Enumerate PRs merged to master since the last update (`gh pr list --state merged --base master --limit 60 --json number,title,mergedAt,labels`) and add a concise, user-facing entry for each genuine change not yet recorded under the right `### Added` / `### Changed` / `### Fixed` / `### Documentation` subheading — SKIP internal loop/CI/priorities-refresh churn. If a new `vX.Y.Z` tag was cut since the last run (`git fetch --tags --force`), rename `## [Unreleased]` to `## [X.Y.Z] - <Month YYYY>` and open a fresh empty `## [Unreleased]` above it. Do not invent entries.
-
-CHANGELOG BLOG POST (blog voice — do NOT auto-merge). If, and only if, enough user-facing work has accumulated since the last changelog post to be worth reading (roughly a week's worth; not a near-empty post every day), draft a short "What's new in Go Micro" post as the next-numbered file in `internal/website/blog/`, mirroring the latest post's frontmatter and prev-nav, and add an entry at the top of `internal/website/blog/index.html`. Base it strictly on the CHANGELOG.
-
-THEN: (A) post a findings report as a comment on this issue (#__ISSUE__) — what's aligned, what drifted, what you fixed, the CHANGELOG entries added, and whether you drafted a blog post (and why/why not). (B) Open ONE auto-merging PR for the SAFE factual work only — coherence/crispness fixes AND the CHANGELOG update (NOT brand/positioning rewrites, NOT the blog post): `git switch -c codex/coherence-__ISSUE__`, `git push -u origin codex/coherence-__ISSUE__`, `gh pr create --base master --label codex --title "<title>" --body "<summary, Closes #__ISSUE__>"`, then `gh pr merge --squash --auto --delete-branch`. (C) If you drafted a changelog blog post, open it as a SEPARATE PR (`codex/coherence-blog-__ISSUE__`, title prefixed `blog:`) and do NOT enable auto-merge — leave it for the human. Same for any brand/positioning copy. Do not use the make_pr tool.

-Act as the architect — the founder lens — for go-micro, running continuously alongside the builders. Hold the whole picture: how the harness, the framework, and the developer UX fit together, what is in flight and what just merged, what to prioritize next, and what is missing or has drifted.
-
-(1) TRACK STATE — scan recently merged PRs and open `codex` PRs/issues to see what shipped and what is being built right now, so the queue reflects reality (drop done items, don't re-queue in-flight work).
-
-(2) ASSESS against the North Star in `.github/loop/NORTH_STAR.md` — lead with its Mission (*make building an agent as easy as building a service, on one runtime*) and re-derive alignment from the CANON: the blog under `internal/website/blog`, the `README`, and the website (read these, don't rely on the North Star alone), then `ROADMAP.md` (Now → Next → Later). Judge every priority against the mission: does it make the services → agents → workflows lifecycle simpler, more cohesive, and more operable? CURRENT GOAL — developer adoption: weight the on-ramp (walkable first-agent tutorial, discoverable examples, docs wayfinding, install friction, debugging, 0→1 and 0→hero) at least as highly as internal hardening; do not let the queue fill entirely with internal depth work. Look at coherence and seams across the core packages (agent, ai, flow, gateway/mcp, gateway/a2a, model, server, store, registry) and the dev inner loop (scaffold → run → chat → inspect → deploy). Flag drift in either direction: work drifting from the mission, or the North Star/website drifting from the lived story in the blog.
-
-(3) MAINTAIN THE QUEUE in `.github/loop/PRIORITIES.md` — a SINGLE ordered list, highest-value first, each item linking a scoped, CI-verifiable issue (#N); roadmap phase is the primary ordering, internal findings (cohesion gaps, DX friction, missing pieces) interleaved by value. For any prioritized gap with no issue, file one: `gh issue create --label codex --label enhancement --title "<scoped task>" --body "<goal, scope, acceptance criteria>"`.
-
-OUTPUT: post a concise assessment as a comment on this issue (#__ISSUE__) — what shipped, what's in flight, the top risks/gaps, and the reasoning behind the ranking. If the ranking actually changed, open ONE PR for `.github/loop/PRIORITIES.md`: `git switch -c codex/planner-__ISSUE__`, `git push -u origin codex/planner-__ISSUE__`, `gh pr create --base master --label codex --title "<title>" --body "<summary, Closes #__ISSUE__>"`, then `gh pr merge --squash --auto --delete-branch`. If the queue is already accurate, just close this issue (`gh issue close __ISSUE__`).
-
-Do NOT make breaking public-API or architectural changes yourself — surface those in the assessment as notes for the human, never as auto-merged changes. Open the PR yourself from the shell with `gh`; do not use the make_pr tool (it is a no-op stub).

-# Repository agent instructions
-
-These instructions apply to the entire repository.
-
-## Pull requests from Codex tasks
-
-When a Codex task makes repository changes and the requested outcome is a PR:
-
-1. Keep the change focused on the assigned issue or prompt.
-2. Run the relevant verification commands and capture their results
-   (`go build ./...`, `go test ./...`, `golangci-lint run ./...`).
-3. Check `git status --short` and review the diff before finishing.
-4. Create a uniquely-named branch under the `codex/` prefix (do not work on
-   `master`, and do not use a generic name like `work`):
-
-   ```sh
-   git switch -c codex/<issue-number>-<short-slug>
-   ```
-5. Stage the intended files and commit on that branch.
-6. Open the pull request yourself with the GitHub CLI, which is installed in the
-   environment and whose `origin` points at this repository, then enable
-   auto-merge so GitHub merges it once the required CI checks pass:
-
-   ```sh
-   git push -u origin HEAD
-   gh pr create --base master --label codex \
-     --title "<concise title>" \
-     --body "<summary of the change and testing, including 'Closes #<issue>'>"
-   gh pr merge --squash --auto --delete-branch
-   ```
-
-The branch should start with `codex/` and the PR should carry the `codex`
-label. Auto-merge waits for the required status checks (build, tests,
-golangci-lint) — never merge a PR manually before CI is green.
-
-Do not just say that a PR was opened, and do **not** rely on the `make_pr` tool:
-in this environment `make_pr` only records the title/body and never pushes a
-branch or creates a PR. The task is not complete until `gh pr create` has opened
-a real pull request and printed its URL.

-follow [Semantic Versioning](https://semver.org/), matching the git tags and
-[GitHub releases](https://github.com/micro/go-micro/releases) (`v6.MINOR.PATCH`).
-Patch releases are cut automatically as the loop merges improvements; the
-`[Unreleased]` section below is kept current between tags and rolled into the

----
-
-## [Unreleased]
-
-### Added
-- **MiniMax provider** — run agents against MiniMax's `MiniMax-M3` model via its OpenAI-compatible endpoint, with tool calling and streaming; auto-detected from the base URL. (`ai/minimax/`)
-
-### Fixed
-- **Plan/delegate completion** — agents now continue unfinished plan steps more reliably, fail checkpointed runs that leave delegated plans unfinished, recover from unknown plan-delegate tool calls, avoid duplicate side effects, and complete timeout paths deterministically. (`agent/`)
-- **AtlasCloud tool calls** — streaming and request fallback handling now recovers tool-call results from provider responses that omit the expected structured fields. (`ai/atlascloud/`)
-
----
-
-## [6.3.13] - July 2026
-
-### Added
-- **`micro loop`** — scaffold an autonomous improvement loop into any repository: GitHub Actions workflows dispatched to an @mention-driven coding agent, across up to five roles — `planner` (ranked queue), `builder` (top item as a single-concern PR, auto-merged on green CI), `triage` (CI failures → fix issues), and opt-in `coherence` (docs/CHANGELOG alignment) and `release` (daily patch tag). Each dispatch role's instruction lives in an editable `.github/loop/prompts/<role>.md` file — the workflow is the mechanism, the prompt is the policy — so a repo customizes behavior without forking the CLI. `micro loop init --roles …` writes it all; `micro loop verify` checks the wiring. This is the loop that maintains go-micro itself, generalized. (`cmd/micro/loop/`)
-
-### Changed
-- **x402 payments** — settlement now covers CDP facilitator authentication and conformance edge cases. (`wrapper/x402/`)
-
-### Fixed
-- **Plan/delegate harnessing** — side effects and notifications are now idempotent and deterministic across duplicate, alias, order-scoped, and reachability scenarios. (`agent/`, `internal/harness/`)
-
-### Documentation
-- **First-agent on-ramp** — quickstart docs now connect the no-secret first-agent transcript, example map, and 0→hero path. (`README.md`, `internal/website/docs/`)
-- **Ollama provider docs** — the provider surface, capability matrix, and examples now document local and cloud behavior. (`internal/website/docs/`, `examples/agent-ollama/`)
-
----
-
-## [6.3.12] - July 2026
-
-### Added
-- **Ollama provider** — run agents against open-weight models locally (`/api/chat`, NDJSON streaming) or via Ollama Cloud (OpenAI-compatible `/v1/chat/completions`, SSE), auto-detected from the base URL, with tool calling in both modes. Point any agent at a non-default endpoint with the new `agent.BaseURL` / `micro.AgentBaseURL` option. (`ai/ollama/`, `examples/agent-ollama/`)
-- **Retrieval-backed agent memory** — agents can recall relevant prior turns by similarity, not just the recent window, with a summarizer hook that compacts older history so long conversations stay in budget. (`agent/`)
-- **Scheduled flows** — a flow can run an agent (or any step) on a cron-style schedule, with the dispatch traced end to end. (`flow/`)
-- **Flow verification/grader loop** — a workflow can grade its own step output against a rubric and retry until it passes, plus run-trace analysis to surface where a flow spends its time. (`flow/`)
-- **A2A streaming & continuity** — outbound agent streaming flows through the A2A binding (`message/stream`), with `tasks/resubscribe` and `input-required` handoffs for multi-turn interop. (`gateway/a2a/`)
-
-### Changed
-- **Agent tool-call resilience** — opt-in retries around agent tool calls, and a fallback that executes tool calls emitted as text by weaker models so they still make progress. (`agent/`)
-- **Hardened agent durability** — terminal failure statuses are classified and surfaced, and durable resume-after-restart is covered by tests. (`agent/`)
-
-### Documentation
-- **"Your first agent" walkthrough** and a canonical 0-to-hero reference path, lowering the on-ramp from install to a running agent. (`internal/website/docs/`)
-- **Discord** linked prominently across the README, website nav/footer, and docs. (`https://discord.gg/G8Gk5j3uXr`)

-## [6.0.0] - June 2026
-
-The AI-native major release. Breaking changes are listed first; everything
-else is additive. See the [v5 → v6 migration guide](internal/website/docs/guides/migration/v5-to-v6.md) — it's a small upgrade.
-
-### Changed (breaking)
-- **Module path is now `go-micro.dev/v6`.** Update imports (`go-micro.dev/v5/...` → `go-micro.dev/v6/...`) and `go install go-micro.dev/v6/cmd/micro@v6`.
-- **TLS verification is on by default.** v5 skipped verification unless `MICRO_TLS_SECURE=true`; v6 verifies by default. `MICRO_TLS_SECURE` is removed — set `MICRO_TLS_INSECURE=true` (or call `tls.InsecureConfig()`) for self-signed/dev certs.
-- **`micro.NewService(name, opts...)` is the service constructor**, symmetric with `NewAgent`/`NewFlow`. `micro.New(name, opts...)` remains as a deprecated alias; the old name-less `micro.NewService(opts...)` form is removed (pass the name positionally). Generators emit the new form.
-- **JWT auth ported in-module.** The external `github.com/micro/plugins/v5/auth/jwt` (pinned to v5) is replaced by `go-micro.dev/v6/auth/jwt/token`, now on the maintained `golang-jwt/jwt/v5`; the deprecated `dgrijalva/jwt-go` dependency is dropped.
-
-### Added
-- **A2A protocol — both directions** — `gateway/a2a` exposes registered agents over the open Agent2Agent (A2A) protocol so agents on other frameworks can discover and call them: Agent Cards are generated from registry metadata (the same way the MCP gateway derives tools), and incoming tasks are translated to the agent's existing `Agent.Chat` RPC, with no per-agent code (`micro a2a serve`). The outbound `a2a.Client` calls external A2A agents by URL, wired into `flow.A2A(url)` (a workflow step) and `delegate` to an `http(s)` URL (from inside an agent). An agent can also serve A2A **directly** without a gateway via `AgentA2A(addr)` (`a2a.NewAgentHandler`), handling tasks in-process. The JSON-RPC binding includes `message/send`, `message/stream` (SSE), `tasks/get`, multi-turn continuation by `taskId`/`contextId`, best-effort push notification callbacks, `tasks/resubscribe`, `input-required` handoffs, and card discovery. (`gateway/a2a/`, `cmd/micro/a2a/`)
-- **Agents (`micro.NewAgent`)** — an agent is a service with an LLM inside: it discovers its assigned services as tools, runs the model's tool loop, registers a `Chat` RPC endpoint, and is reachable like any service. `Ask` for programmatic use; `micro chat` discovers and routes to agents; `micro agent list`/`describe`. (`agent/`)
-- **Plan & delegate** — two built-in agent tools added to every agent: `plan` (an ordered, store-persisted plan surfaced back in the prompt) and `delegate` (hand a self-contained subtask to a registered agent over RPC, otherwise to an ephemeral sub-agent). No harness or graph — they're plain tools. (`agent/builtin.go`, `examples/agent-plan-delegate/`)
-- **Agent guardrails** — `MaxSteps` (stop on count), `LoopLimit` (stop repeated no-progress calls; on by default), and `ApproveTool` (human-in-the-loop / policy gate before each action), enforced at the one point every tool call passes through. (`agent/`, guide + blog)
-- **Pluggable agent memory & custom tools** — durable store-backed conversation memory by default, swappable via `AgentMemory`; register any function as a tool with `AgentTool`.
-- **Workflows (`micro.NewFlow`)** — event-driven orchestration that maps to Anthropic's workflow/agent split: an event triggers a deterministic step (or ordered durable steps), or dispatches to an agent with `FlowAgent`. (`flow/`)
-- **Flow loops (`FlowLoop`)** — a flow step that runs a body step repeatedly, carrying state across passes, until a stop condition is met or a hard iteration cap is hit. Stop on a code-defined predicate (`FlowUntil`) or let the model judge it done (`FlowUntilLLM` — the supervised "Ralph" loop); `FlowLoopMax` is the guardrail that guarantees termination, and `FlowOnIteration` reports progress. (`flow/loop.go`, `examples/flow-loop/`, guide)
-- **x402 payments** — opt-in per-call payments for tools via the x402 standard, with a pluggable facilitator and a consumer-side client + budget; the MCP gateway can advertise and require payment per tool. (`wrapper/x402/`, guide + blog)
-- **Scoped store state** — `store.Scope(s, database, table)` returns a store handle that confines every operation to a database/table without mutating the shared store (unlike `Init(Table(...))`, which is process-global and races between co-located components). Services, agents, and flows now each keep their state in their own table (`service/{name}`, `agent/{name}`, `flow/{name}`); the service path replaces the old `Init(store.Table(name))` global mutation with a scoped handle.
-- **Flow discovery & history CLI** — running flows now register in the registry as `type=flow` (and deregister on `Stop`), so they're discoverable like agents: `micro flow list` shows running flows, `micro flow runs <name>` shows a flow's durable run history from the store, and `micro agent history <name>` shows an agent's stored conversation. Live state comes from the registry; durable history from the scoped store.
-- **Durable workflows** — a flow can now be an ordered list of steps (a task with stages) that is checkpointed before and after each step, so a run survives a crash and resumes where it stopped without re-running completed steps. State carries a typed payload plus a `Stage` marker; flow-level `Retry` with a per-step override; runs retained for audit unless `DeleteOnSuccess`. Step actions: `Call` (RPC), `LLM` (model turn), `Dispatch` (to an agent), or any `StepFunc`. Durability is a pluggable `Checkpoint` (store-backed by default; implement the interface for Temporal/Restate). Runnable example: `examples/flow-durable/`. Blog: "Durable Workflows" (`internal/website/blog/24.md`).
-- **Agent tool-execution wrappers** — `AgentWrapTool` registers middleware around an agent's tool calls, the tool-side analogue of `client.CallWrapper`/`server.HandlerWrapper`. Use it for logging, metrics, retries, or policy; wrappers compose outermost-first and run outside the built-in guardrails. Includes a runnable example with observe + retry wrappers (`examples/agent-wrap-tool/`).
-- **Agent platform showcase** — full platform example (Users, Posts, Comments, Mail) mirroring [micro/blog](https://github.com/micro/blog), demonstrating how existing microservices become agent-accessible with zero code changes (`examples/mcp/platform/`).
-- **Blog post: "Your Microservices Are Already an AI Platform"** — walkthrough of agent-service interaction patterns using real-world services (`internal/website/blog/7.md`).
-- **Circuit breakers for MCP gateway** — per-tool circuit breakers protect downstream services from cascading failures. Configurable max failures, open-state timeout, and half-open probing. Available via `Options.CircuitBreaker` and `--circuit-breaker` CLI flag (`gateway/mcp/circuitbreaker.go`).
-- **Helm chart for MCP gateway** — official Helm chart at `deploy/helm/mcp-gateway/` with Deployment, Service, ServiceAccount, HPA, and Ingress templates. Supports Consul/etcd/mDNS registries, JWT auth, rate limiting, audit logging, per-tool scopes, TLS ingress, and auto-scaling.
-- **MCP gateway benchmarks** — comprehensive benchmark suite for tool listing, lookup, auth, rate limiting, and JSON serialization (`gateway/mcp/benchmark_test.go`)
-- **Workflow example** — cross-service orchestration demo with Inventory, Orders, and Notifications services showing agents chaining multi-step workflows from natural language (`examples/mcp/workflow/`)
-- **Docker Compose deployment** — production-like setup with Consul registry, standalone MCP gateway, and Jaeger tracing in one `docker-compose up` (`examples/deployment/`)

-## [2026.03] - March 2026
-
-### Added
-
-#### Developer Experience
-- **`micro new` MCP templates** — `micro new myservice` generates MCP-enabled services with doc comments, `@example` tags, and `WithMCP()` wired in. Use `--no-mcp` to opt out.
-- **`micro.NewService("name")` unified API** — single way to create services: `micro.NewService("greeter")` or `micro.NewService("greeter", micro.Address(":8080"))`. Replaces `micro.NewService()` + `service.New()` dual API.
-- **`service.Handle()` simplified registration** — register handlers with `service.Handle(new(Greeter))` instead of manual `server.NewHandler` + `server.Handle`.
-- **`micro.NewGroup()` modular monoliths** — run multiple services in one binary with shared lifecycle: `micro.NewGroup(users, orders).Run()`.
-- **`mcp.WithMCP()` one-liner** — add MCP to any service with a single option: `micro.NewService("name", mcp.WithMCP(":3001"))`.
-- **CRUD example** — contact book service with 6 operations, rich agent docs, and validation patterns (`examples/mcp/crud/`).
-
-#### MCP Gateway
-- **WebSocket transport** — bidirectional JSON-RPC 2.0 streaming over WebSocket for real-time agent communication (`gateway/mcp/websocket.go`).
-- **OpenTelemetry integration** — full span instrumentation across HTTP, stdio, and WebSocket transports with W3C trace context propagation (`gateway/mcp/otel.go`).
-- **Standalone gateway binary** — `micro-mcp-gateway` with Docker support for running the MCP gateway independently of services.
-- **Per-tool auth scopes** — service-level (`server.WithEndpointScopes()`) and gateway-level (`Options.Scopes`) scope enforcement with bearer token auth.
-- **Rate limiting** — per-tool token bucket rate limiting (`Options.RateLimit`).
-- **Audit logging** — immutable audit records per tool call with trace ID, account, scopes, duration, and errors (`Options.AuditFunc`).

-# CLAUDE.md - Go Micro Project Guide
-
-## Project Overview
-
-Go Micro is a framework for distributed systems development in Go. It provides pluggable abstractions for service discovery, RPC, pub/sub, config, auth, storage, and more.
-
-The framework is evolving into an **AI-native platform** where every microservice is automatically accessible to AI agents via the Model Context Protocol (MCP).
-
-## Build & Test
-
-```bash
-# Run all tests
-make test
-
-# Run tests for a specific package
-go test ./gateway/mcp/...
-go test ./ai/...
-go test ./model/...

-# Lint
-make lint
-
-# Format
-make fmt
-
-# Build CLI
-go build -o micro ./cmd/micro

-## Key Architectural Decisions
-
-- **Plugin architecture**: All abstractions use Go interfaces. Defaults work out of the box, everything is swappable.
-- **Progressive complexity**: Zero-config for development, full control for production.
-- **AI-native by default**: Every service is automatically an MCP tool. No extra code needed.
-- **In-repo plugins**: Plugins live in the main repo to avoid version compatibility issues.
-- **Reflection-based registration**: Handlers are registered via reflection for minimal boilerplate.
-
-## Code Conventions
-
-- Standard Go conventions (gofmt, golint)
-- Functional options pattern for configuration (`WithX()` functions)
-- Interface-first design: define the interface, then implement
-- Tests alongside code (not in separate test directories)
-- Commit messages: imperative mood, concise summary line
-
-## Current Focus & Priorities (March 2026)
-
-### Status
-- **Q1 2026 (MCP Foundation):** COMPLETE
-- **Q2 2026 (Agent DX):** COMPLETE (100%)
-- **Q3 2026 (Production):** 50% complete (ahead of schedule)
-
-### Priority 1: Agent Showcase & Examples
-Build compelling demos showing agents interacting with go-micro services in realistic scenarios.
-
-### Priority 2: Additional Protocol Support
-- gRPC reflection-based MCP
-- HTTP/3 support
-
-### Priority 3: Kubernetes & Deployment
-- Helm Charts for MCP gateway
-- Kubernetes Operator with CRDs
-
-### Recently Completed
-- **Agent Plan & Delegate** - Two built-in agent tools: `plan` (ordered plan persisted to store-backed memory, surfaced in the prompt) and `delegate` (hand a subtask to another agent — RPC to a registered agent, else an ephemeral sub-agent with isolated context). Added automatically to every agent; no harness or graph. (`agent/builtin.go`, `examples/agent-plan-delegate/`)
-- **`micro new` MCP Templates** - Scaffolds MCP-enabled services with doc comments, `@example` tags, `WithMCP()`. `--no-mcp` to opt out.
-- **CRUD Example** - Contact book service with 6 operations, rich agent docs (`examples/mcp/crud/`)
-- **Migration Guide** - "Add MCP to Existing Services" guide with 3 approaches
-- **Troubleshooting Guide** - Common MCP issues and solutions
-- **Error Handling Guide** - Patterns for agent-friendly error responses
-- **Documentation Guides** - Six guides: AI-native services, MCP security, tool descriptions, agent patterns, error handling, troubleshooting
-- **WithMCP Option** - One-line MCP setup (`gateway/mcp/option.go`)
-- **Agent Playground Redesign** - Chat-focused UI with collapsible tool calls
-- **Standalone Gateway Binary** - `micro-mcp-gateway` with Docker support
-- **WebSocket Transport** - Bidirectional JSON-RPC 2.0 streaming (`gateway/mcp/websocket.go`)
-- **OpenTelemetry Integration** - Full span instrumentation with W3C trace context (`gateway/mcp/otel.go`)
-- **LlamaIndex SDK** - Python package with RAG examples (`contrib/go-micro-llamaindex/`)

-## Coordination with Codex
-
-Go Micro is maintained by two AI tools — **Claude Code** (you) and **Codex** (its playbook is [CODEX.md](CODEX.md)) — plus the human maintainer, who routes work and owns every merge. To work side by side without collisions:
-
-- **Lanes / branches.** You work on `claude/*` branches; Codex on `codex/*`. Never push to Codex's branch, and never have both agents committing the same branch at once.
-- **Base PRs on `master`; don't stack on Codex's in-flight branch.** If that base squash-merges, your commit gets orphaned (this happened — the #3007 fixes had to be re-landed). If the code you need isn't merged yet, wait for it, then branch off `master`. To improve an *open* Codex PR, fix it in place (once Codex is done with the branch, or via an `@codex` comment on the PR) rather than a separate stacked PR.
-- **One concern per PR.** Single-purpose PRs; don't bundle (e.g.) a feature with a docs change.
-- **Cross-review.** Review Codex's PRs before merge — mechanical fixes you can land yourself (based on `master`), but design/scope/positioning calls go to the human; don't silently rewrite Codex's intent. Codex reviews yours via `@codex review`.
-- **Dispatching Codex.** Start a task by commenting `@codex <instruction>` on an issue/PR (that issue/PR is its context). `@codex review` is reserved for review; any other instruction starts a *task*. It's consequential (spends a Codex task slot, pushes commits) and **serial** (one task at a time) — so dispatch one task at a time, only on the human's go-ahead, and never write a literal `@codex` in a comment unless you intend to trigger it (write "Codex" in prose otherwise).
-- **CI is the gate.** `go build`, `go test`, `golangci-lint` (blocking), and `make harness` must pass before merge. `internal/harness/` and `examples/` are excluded from errcheck; everything else gets the full set.
-- **Backlog = GitHub issues**, each a scoped, self-contained brief with acceptance criteria.

-## Contributing
-
-See [CONTRIBUTING.md](CONTRIBUTING.md) for full guidelines. Key points:
-- Open an issue before large changes
-- Include tests for new features
-- Run `make test` and `make lint` before submitting
-- Follow commit message format: `type: description` (e.g., `feat: add WebSocket transport`)

-# Codex Maintainer Playbook
-
-Go Micro has six months of Codex access through OpenAI's Codex for Open Source
-program. Use it to increase maintainer throughput without changing the project's
-bar for review, tests, or design taste.
-
-## Operating principles
-
-1. **Humans set direction; Codex accelerates execution.** Maintainers choose the
-   issue, constraints, and acceptance criteria. Codex drafts, investigates, and
-   verifies.
-2. **Small, reviewable changes win.** Prefer focused PRs that can be understood
-   in one sitting over large speculative rewrites.
-3. **Keep the contract green.** Every Codex-assisted change should preserve the
-   CLI-first getting-started flow, the harnesses, `make test`, and `make lint`.
-4. **Document while coding.** If behavior changes, ask Codex to update examples,
-   guides, and release notes in the same branch.
-5. **No blind merges.** Codex output is treated like any contributor output:
-   reviewed by a maintainer, backed by tests, and checked for public API impact.
-
-## Coordination with Claude Code
-
-Go Micro is maintained by two AI tools — **Codex** (you) and **Claude Code** (its guide is [CLAUDE.md](CLAUDE.md)) — plus the human maintainer, who routes work and owns every merge.
-
-- **Lanes / branches.** You work on `codex/*` branches; Claude Code on `claude/*`. Never push to a branch the other owns, and never have both agents on one branch at once.
-- **Base PRs on `master`.** Don't stack a PR on another agent's in-flight branch — if that base squash-merges, your changes can be orphaned. If the code you need isn't merged yet, wait, then branch off `master`. To improve a PR that hasn't merged, push to that PR's branch rather than opening a separate stacked PR — keep the change one mergeable unit.
-- **One concern per PR.** Keep each PR single-purpose so a reviewer can read it in one sitting; don't bundle unrelated changes (e.g. a feature plus a docs rebrand).
-- **Cross-review before merge.** Claude Code reviews your PRs; you review its with `@codex review`. A fresh pass from the other model catches what the author misses.
-- **Dispatch.** Maintainers (or Claude Code) start your tasks with `@codex <instruction>` on the relevant issue/PR — that's your context. `@codex review` is review; any other instruction is a *task*. You run one task at a time: take the current one to a clean, green PR before the next is dispatched.
-- **CI is the gate.** `go build`, `go test`, `golangci-lint` (blocking), and `make harness` must pass; never merge red. `internal/harness/` and `examples/` are excluded from errcheck; everything else gets the full set.
-- **Backlog = GitHub issues**, each a scoped brief with acceptance criteria.
-
-## Best uses
-
-### 1. PR review and triage
-
-- Summarize a PR: changed surface area, public API impact, tests added or missing.
-- Ask for targeted review passes: concurrency, cancellation, security, backwards
-  compatibility, docs drift, and examples.
-- Convert review findings into small patch suggestions or issue comments.
-
-### 2. Issue reproduction
-
-- Turn bug reports into failing tests or runnable reproduction scripts.
-- Minimize flakes by isolating registry, broker, store, transport, and AI-provider
-  dependencies behind deterministic fakes where possible.
-- Attach the exact command that reproduces the failure to the issue.
-
-### 3. Release support
-
-- Draft changelog entries from merged commits, grouped by feature, fix, docs, and
-  compatibility notes.
-- Check that `README.md`, `ROADMAP.md`, website docs, examples, and `CHANGELOG.md`
-  agree before tagging.
-- Run dry-run release commands and summarize blockers.
-
-### 4. Docs and examples
-
-- Keep the 0→1 path current: scaffold, run, call, chat, inspect.
-- Keep the 0→hero example current: a realistic multi-agent system that exercises
-  agents, services, flows, MCP, A2A, and observability.
-- Add runnable examples for new primitives before adding broad prose.
-
-### 5. Hardening backlog
-
-Use Codex to break roadmap items into small PRs, especially:
-
-- cross-provider conformance scenarios for all supported AI providers;
-- timeout, cancellation, retry, and rate-limit behavior;
-- durable agent loops on top of the existing checkpoint model;
-- streaming across `ai.Stream` and A2A;
-- agent run metadata mapped to OpenTelemetry spans.
-
-## Suggested weekly loop
-
-1. Pick one maintenance lane: reviews, bugs, release prep, docs, or hardening.
-2. Ask Codex for a branch-sized plan with acceptance criteria and test commands.
-3. Have Codex implement the smallest valuable slice.
-4. Run the relevant checks locally and in CI.
-5. Review the diff as maintainer-owned code, then merge or send it back.
-6. Record any recurring prompt, check, or failure mode in this playbook.
-
-
-## First two weeks
-
-Do not start with a giant feature. Start by making Codex pay rent on maintenance
-work that is already on the roadmap and easy to review.
-
-### Day 1: set up the review loop
-
-1. Pick three recent PRs or commits: one feature, one bug fix, and one docs-only
-   change.
-2. Ask Codex to review each using the PR review template below.
-3. Compare Codex findings with maintainer judgment. Keep the checks that found
-   real issues; delete the noisy ones.
-4. Turn the final review prompt into a saved project note or issue comment
-   template.
-
-Success means Codex can produce a useful first-pass review in under ten minutes
-without blocking a maintainer on false positives.
-
-### Days 2-3: make bugs reproducible
-
-1. Pick one open bug or flaky area.
-2. Ask Codex for a failing test only. Do not allow a fix in the first pass.
-3. Review the test for whether it captures the real contract.
-4. In a second branch, ask Codex to fix the failure with the smallest patch.
-
-Success means every accepted bug fix starts with a regression test or deterministic
-harness case.
-
-### Days 4-5: audit the getting-started contract
-
-Run through the 0→1 path from a clean checkout and ask Codex to patch only the
-first broken or confusing step. The target is not new prose; it is a runnable
-path that works exactly as documented.
-
-Candidate checks:
-
-```sh
-make test
-make harness
-make lint
-go run ./examples/hello-world
-go run ./internal/harness/universe
-```
-
-### Week 2: choose one roadmap slice
-
-Pick one hardening item and break it into PRs that each land independently. The
-best first slice is usually test infrastructure, not product code.
-
-Recommended order:
-
-1. **Provider conformance skeleton**: define one deterministic agent scenario and
-   gate real-provider runs on credentials.
-2. **Cancellation audit**: trace `context.Context` propagation through one package
-   at a time.
-3. **Docs drift audit**: compare `README.md`, `ROADMAP.md`, website docs, and
-   examples for one shipped feature.
-4. **Release checklist dry run**: have Codex build a release-blocker list from the
-   diff since the previous tag.
-
-## Standing task queue
-
-Keep Codex busy on tasks with clear acceptance criteria:
-
-| Priority | Task | Acceptance criteria |
-| --- | --- | --- |
-| P0 | PR first-pass review | Summary, risks, required changes, and exact verification commands. |
-| P0 | Bug reproduction | A failing test or harness case committed before the fix. |
-| P0 | 0→1 docs check | Fresh-checkout commands work as written or a patch fixes the first break. |
-| P1 | Cross-provider conformance | One scenario runs against fakes by default and real providers when keys exist. |
-| P1 | Cancellation hardening | Tests prove timeout/cancel behavior for the touched package. |
-| P1 | Release audit | Changelog, docs, examples, and migration notes agree before tagging. |
-| P2 | Example polish | Example is runnable, linked from docs, and covered by a lightweight check. |
-
-## What not to use Codex for yet
-
-- Broad rewrites without a failing test, benchmark, or public design note.
-- Public API changes before a maintainer writes the compatibility story.
-- Large generated docs that nobody has run.
-- Provider-specific behavior that is not checked against the shared `ai.Model`
-  contract.

-## How Go Micro is built
-
-Go Micro is developed by an **autonomous improvement loop** — a planner, a
-generator, and a separate evaluator, running as scheduled GitHub Actions with a
-human setting direction. It's the framework's own thesis (an agent operating a
-system) pointed at itself: an agent harness, built by agents. The full process —

-Go Micro is an **agent harness** and service framework for Go.
+Go Micro is a framework for distributed systems development.
 
-**Community:** questions, ideas, or just want to build alongside us? [Join the Discord](https://discord.gg/G8Gk5j3uXr).
+**[📖 Documentation](https://go-micro.dev/docs/)** | [Sponsor the project](https://github.com/sponsors/micro) | [Discord](https://discord.gg/jwTYuUVAGh)
 
-A harness is the runtime around an agent: the tools it can call, the memory it keeps, the guardrails that bound it, the workflows that trigger it, the services it depends on, and the protocols other agents use to reach it. 
+## Overview
 
-Go Micro gives you the harness as Go code. Build an agent and it gets a model, memory, tools, planning, delegation, guardrails, and service discovery; it is reachable over [MCP](https://modelcontextprotocol.io/) and [A2A](https://a2a-protocol.org). Write services and every endpoint becomes an AI-callable tool. Orchestrate the deterministic parts with durable flows. Agents, services, and flows share one runtime because an agent is a distributed system, and building one is building a service.
+Go Micro provides the core requirements for distributed systems development including RPC and Event driven communication.
+The Go Micro philosophy is sane defaults with a pluggable architecture. We provide defaults to get you started quickly
+but everything can be easily swapped out.

+Go Micro abstracts away the details of distributed systems. Here are the main features.
 
-**Want to support Go Micro and see your logo here?** [Become a sponsor](https://discord.gg/G8Gk5j3uXr) — reach out on Discord.
+- **Authentication** - Auth is built in as a first class citizen. Authentication and authorization enable secure
+  zero trust networking by providing every service an identity and certificates. This additionally includes rule
+  based access control.
 
-## Commercial Support
+- **Dynamic Config** - Load and hot reload dynamic config from anywhere. The config interface provides a way to load application
+  level config from any source such as env vars, file, etcd. You can merge the sources and even define fallbacks.
 
-Running Go Micro in production, or building on it and want help? Paid **support, consulting, training, and retainers** are available directly from the maintainer — and they're what keep the project maintained. See [**Support**](SUPPORT.md) for the tiers, or [open a request](https://github.com/micro/go-micro/issues/new?template=commercial_support.md).
+- **Data Storage** - A simple data store interface to read, write and delete records. It includes support for many storage backends
+in the plugins repo. State and persistence becomes a core requirement beyond prototyping and Micro looks to build that into the framework.
 
-## Contents
+- **Service Discovery** - Automatic service registration and name resolution. Service discovery is at the core of micro service
+  development. When service A needs to speak to service B it needs the location of that service. The default discovery mechanism is
+  multicast DNS (mdns), a zeroconf system.

-- [Docs](#docs)
+- **Load Balancing** - Client side load balancing built on service discovery. Once we have the addresses of any number of instances
+  of a service we now need a way to decide which node to route to. We use random hashed load balancing to provide even distribution
+  across the services and retry a different node if there's a problem.
 
-## Quick Start
+- **Message Encoding** - Dynamic message encoding based on content-type. The client and server will use codecs along with content-type
+  to seamlessly encode and decode Go types for you. Any variety of messages could be encoded and sent from different clients. The client
+  and server handle this by default. This includes protobuf and json by default.
 
-Install the CLI:
+- **RPC Client/Server** - RPC based request/response with support for bidirectional streaming. We provide an abstraction for synchronous
+  communication. A request made to a service will be automatically resolved, load balanced, dialled and streamed.
+
+- **Async Messaging** - PubSub is built in as a first class citizen for asynchronous communication and event driven architectures.
+  Event notifications are a core pattern in micro service development. The default messaging system is a HTTP event message broker.
+
+- **MCP Integration** - An MCP gateway you can integrate as a library, server or CLI command which automatically exposes services
+  as tools for agents or other AI applications. Every service/endpoint get's converted into a callable tool.
+
+- **Pluggable Interfaces** - Go Micro makes use of Go interfaces for each distributed system abstraction. Because of this these interfaces
+  are pluggable and allows Go Micro to be runtime agnostic. You can plugin any underlying technology.
+
+## Getting Started
+
+To make use of Go Micro 
 
 ```bash
-# Binary (no Go required)
-curl -fsSL https://go-micro.dev/install.sh | sh
-
-# Or with Go
-go install go-micro.dev/v6/cmd/micro@latest
+go get go-micro.dev/v5@latest
 ```
 
-### Fastest start — no API key
-
-Scaffold a service, run it, call it:
-
-```bash
-micro new helloworld
-cd helloworld
-micro run
-```
-
-Then in another terminal:
-
-```bash
-curl -X POST http://localhost:8080/api/helloworld/Helloworld.Call \
-  -H 'Content-Type: application/json' -d '{"name":"World"}'
-```
-
-This install → scaffold → run → call path is covered by no-secret CI harnesses. To
-verify just the local installer and first-run CLI boundaries without network
-access or provider keys, use:
-
-```bash
-make install-smoke
-```
-
-To run the broader local contract (including the [0→hero services → agents → workflows path](internal/website/docs/guides/zero-to-hero.md),
-chat/inspect CLI boundaries, and deploy dry-run), use:
-
-```bash
-make harness
-```
-
-### First agent on-ramp
-
-After install and the first `micro new`/`micro run` smoke check, take the
-walkable agent path in this order:
-
-1. [No-secret first-agent transcript](internal/website/docs/guides/no-secret-first-agent.md) — run the
-   maintained support agent with a mock model and see services → agents → workflows succeed without a key.
-2. [Your First Agent](internal/website/docs/guides/your-first-agent.md) — build a
-   service-backed agent and talk to it with `micro chat`.
-3. [Debugging your agent](internal/website/docs/guides/debugging-agents.md) — use
-   `micro agent inspect`, run history, memory, and provider checks when the first
-   conversation does something unexpected.
-4. [0→hero Reference](internal/website/docs/guides/zero-to-hero.md) — complete the
-   services → agents → workflows loop with scaffold, run, chat, inspect, flow
-   history, and deploy dry-run commands that match the maintained harness.
-
-### Generate from a prompt — with an LLM key
-
-Set a provider key, describe what you want, and the AI designs services, writes handlers, compiles, and starts them:
-
-```bash
-export ANTHROPIC_API_KEY=sk-ant-...   # or OPENAI_API_KEY, GEMINI_API_KEY, ...
-micro run --prompt "a task management system with categories" --provider anthropic
-```
-
-The AI designs the architecture, you review it, then it generates handlers with real business logic, compiles them, and starts them:
-
-```
-Services:
-  ● task — Task management with status tracking
-  ● project — Project organization
-
-Generate? [Y/n]
-
-Micro
-  Services:
-    ● task
-    ● project
-  Agents:
-    ◆ agent
-```
-
-Then talk to your services from the console:
-
-```
-> Create a project called Launch, then add three tasks to it
-
-→ project_Project_Create({"name":"Launch"})
-← {"record":{"id":"p1..."},"success":true}
-→ task_Task_Create({"title":"Design specs","project_id":"p1..."})
-→ task_Task_Create({"title":"Write code","project_id":"p1..."})
-→ task_Task_Create({"title":"Ship it","project_id":"p1..."})
-
-Created project Launch and added three tasks to it.
-```
-
-When you need a capability that doesn't exist, the agent generates a new service mid-conversation:
-
-```
-> I need to track shipping. Create a shipment for order 123 to London.
-
-  ⚡ generating shipping service...
-  ✓ shipping
-  → shipping_Shipping_Create({"order_id":"123","destination":"London"})
-  ← {"record":{"id":"xyz...","status":"pending"}}
-
-  Created shipment for order 123 going to London.
-```
-
-Edit the generated code by hand at any time — re-running preserves your changes. [Read more](https://go-micro.dev/blog/13).
-
-## Why an Agent Harness
-
-The first wave of agent frameworks helped developers put a model in a loop. The next problem is operating that loop: connecting it to real tools, scoping what it can touch, preserving state, routing work to specialists, recovering from failures, observing what happened, and letting other agents call it. That is harness work.
-
-Go Micro's answer is to make the harness the same thing you already deploy:
-
-- **Tools are services** — endpoint metadata becomes tool schema; RPC executes the call.
-- **Agents are services** — they register, discover, load-balance, and expose `Agent.Chat`.
-- **Workflows are durable code paths** — use flows when the path is known; dispatch to agents when it is not.
-- **Safety lives at execution** — `MaxSteps`, `LoopLimit`, `ApproveTool`, and tool wrappers run where actions happen.
-- **Interop is built in** — MCP for tools, A2A for agents, x402 for paid tools.
-
-Use Go Micro when the agent has to operate a system, not just answer a prompt.
-
-## Writing Services
-
-Under the hood, a service is a struct with methods. Doc comments and `@example` tags become tool descriptions for AI agents automatically.
+Create a service and register a handler
 
 ```go
 package main
 
 import (
-    "context"
-
-    "go-micro.dev/v6"
+        "go-micro.dev/v5"
 )
 
 type Request struct {
-    Name string `json:"name"`
+        Name string `json:"name"`
 }
 
 type Response struct {
-    Message string `json:"message"`
+        Message string `json:"message"`
 }
 
 type Say struct{}
 
-// Hello greets a person by name.
-// @example {"name": "Alice"}
 func (h *Say) Hello(ctx context.Context, req *Request, rsp *Response) error {
-    rsp.Message = "Hello " + req.Name
-    return nil
+        rsp.Message = "Hello " + req.Name
+        return nil
 }
 
 func main() {
-    service := micro.NewService("greeter")
-    service.Handle(new(Say))
-    service.Run()
+        // create the service
+        service := micro.New("helloworld")
+
+        // register handler
+        service.Handle(new(Say))
+
+        // run the service
+        service.Run()
 }
 ```
 
-Run it and everything is accessible — REST, gRPC, MCP, agent playground:
+Set a fixed address
+
+```go
+service := micro.NewService(
+    micro.Name("helloworld"),
+    micro.Address(":8080"),
+)
+```
+
+Call it via curl
+
+```bash
+curl -XPOST \
+     -H 'Content-Type: application/json' \
+     -H 'Micro-Endpoint: Say.Hello' \
+     -d '{"name": "alice"}' \
+      http://localhost:8080
+```
+
+## MCP & AI Agents
+
+Go Micro is designed for an **agent-first** workflow. Every service you build automatically becomes a tool that AI agents can discover and use via the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/).
+
+- **[🤖 Agent Playground](https://go-micro.dev/docs/mcp.html)** — Chat with your services through an interactive AI agent at `/agent`
+- **[🔧 MCP Tools Registry](https://go-micro.dev/docs/mcp.html)** — Browse all services exposed as AI-callable tools at `/api/mcp/tools`
+- **[📖 MCP Documentation](https://go-micro.dev/docs/mcp.html)** — Full guide to MCP integration, auth, and scopes
+
+### Services as Tools
+
+Write a normal Go Micro service and it's instantly available as an MCP tool:
+
+```go
+// SayHello greets a person by name.
+// @example {"name": "Alice"}
+func (g *GreeterService) SayHello(ctx context.Context, req *HelloRequest, rsp *HelloResponse) error {
+    rsp.Message = "Hello " + req.Name
+    return nil
+}
+```
+
+Run with `micro run` and the agent playground and MCP tools registry are ready:
 
 ```bash
 micro run
-# Dashboard:   http://localhost:8080
-# API:         http://localhost:8080/api/{service}/{method}
-# Agent:       http://localhost:8080/agent
-# MCP Tools:   http://localhost:8080/mcp/tools
+# Agent Playground:  http://localhost:8080/agent
+# MCP Tools:         http://localhost:8080/api/mcp/tools
 ```
 
-You can also scaffold a service from a template:
+Use `micro mcp serve` for local AI tools like Claude Code, or connect any MCP-compatible agent to the HTTP endpoint.
+
+See the [MCP guide](https://go-micro.dev/docs/mcp.html) for authentication, scopes, and advanced usage.
+
+## Examples
+
+Check out [/examples](examples/) for runnable code:
+- [hello-world](examples/hello-world/) - Basic RPC service
+- [web-service](examples/web-service/) - HTTP REST API
+- [mcp](examples/mcp/) - MCP integration with AI agents
+
+See [all examples](examples/README.md) for more.
+
+## Protobuf
+
+Install the code generator and see usage in the docs:
 
 ```bash
-micro new helloworld
-micro new contacts --template crud
+go install go-micro.dev/v5/cmd/protoc-gen-micro@v5.16.0
 ```
 
-## Building Agents
+> **Note:** Use a specific version instead of `@latest` to avoid module path conflicts. See [releases](https://github.com/micro/go-micro/releases) for the latest version.
 
-An Agent is a service with an LLM inside it. It has a proto-defined `Agent.Chat` RPC endpoint, registers in the registry, and is callable like any service:
+Docs: [`internal/website/docs/getting-started.md`](internal/website/docs/getting-started.md)
 
-```go
-agent := micro.NewAgent("task-mgr",
-    micro.AgentServices("task", "project"),
-    micro.AgentPrompt("You manage tasks and projects. You understand deadlines and priorities."),
-    micro.AgentProvider("anthropic"),
-)
-agent.Run()
+## Command Line
+
+Install the CLI:
+
+```
+go install go-micro.dev/v5/cmd/micro@v5.16.0
 ```
 
-The agent discovers its services from the registry, scopes its tools to their endpoints, and maintains conversation memory in the store. It registers itself so `micro chat` and other agents can find it.
+> **Note:** Use a specific version instead of `@latest` to avoid module path conflicts. See [releases](https://github.com/micro/go-micro/releases) for the latest version.
 
-```go
-// Programmatic interaction
-resp, _ := agent.Ask(ctx, "What tasks are overdue?")
-fmt.Println(resp.Reply)
-```
-
-Multiple agents coordinate via RPC — each is a service with an `Agent.Chat` endpoint. `micro chat` routes to the right one.
+### Quick Start
 
 ```bash
-micro agent list                    # list registered agents
-micro call task-mgr Agent.Chat '{"message": "What tasks are overdue?"}'
+micro new helloworld   # Create a new service
+cd helloworld
+micro run              # Run with API gateway and hot reload
 ```
 
-### Plan & Delegate
+Then open http://localhost:8080 to see your service and call it from the browser.
 
-Every agent gets two built-in harness capabilities, exposed as tools — no extra setup or separate graph runtime:
+### Development Workflow
 
-- **`plan`** — for multi-step work, the agent records an ordered plan in its store-backed memory and stays oriented across turns.
-- **`delegate`** — the agent hands a self-contained subtask to another agent. If a registered agent already owns the relevant services, the hand-off goes over RPC to that agent; otherwise a focused, short-lived sub-agent is created for the subtask with its own isolated context.
+| Stage | Command | Purpose |
+|-------|---------|---------|
+| **Develop** | `micro run` | Local dev with hot reload and API gateway |
+| **Build** | `micro build` | Compile production binaries |
+| **Deploy** | `micro deploy` | Push to a remote Linux server via SSH + systemd |
+| **Dashboard** | `micro server` | Optional production web UI with JWT auth |
 
-This keeps intelligence distributed: an agent doesn't need to know *how* to do everything, only *who* does. See [examples/agent-plan-delegate](examples/agent-plan-delegate/).
+### micro run
 
-```go
-// A sub-agent is just an agent — created with New, talked to with Ask.
-// delegate-first: reuse a registered agent, or spin up a focused one.
-resp, _ := agent.Ask(ctx, "Plan the launch, create the tasks, and have comms notify the owner.")
-```
+`micro run` starts your services with:
+- **Web Dashboard** - Browse and call services at `/`
+- **Agent Playground** - AI chat with MCP tools at `/agent`
+- **API Explorer** - Browse endpoints and schemas at `/api`
+- **API Gateway** - HTTP to RPC proxy at `/api/{service}/{method}` (no auth in dev mode)
+- **MCP Tools** - Services as AI tools at `/api/mcp/tools`
+- **Health Checks** - Aggregated health at `/health`
+- **Hot Reload** - Auto-rebuild on file changes
 
-### Batteries included, pluggable
-
-Just as a service composes pluggable abstractions (registry, broker, store), an agent composes a **model**, **memory**, and **tools** — sane defaults out of the box, each swappable.
-
-```go
-agent := micro.NewAgent("assistant",
-    micro.AgentProvider("anthropic"),                 // model — swap the provider
-    micro.AgentCompactMemory(40, 12),                 // memory — durable, summarized, recallable
-    micro.AgentTool("weather", "Get the weather for a city",
-        map[string]any{"city": map[string]any{"type": "string"}},
-        func(ctx context.Context, in map[string]any) (string, error) {
-            return getWeather(in["city"].(string))    // tools beyond your services — any function
-        }),
-    micro.AgentMaxSteps(8),                            // guardrails
-)
-```
-
-**Memory** is durable and store-backed by default (Postgres, NATS KV, or file), so an agent picks up where it left off after a restart — or supply your own with `AgentMemory`. Long-running agents can opt into `AgentCompactMemory(maxMessages, keepRecent)`: older turns are collapsed into a deterministic summary, recent turns stay verbatim, and relevant archived turns are recalled on future asks without replaying the whole conversation. **Tools** are your services automatically, plus any function you register with `AgentTool`.
-
-### Paid tools (x402)
-
-Every endpoint is an AI-callable tool — and it can be a *paid* tool. Go Micro supports [x402](https://x402.org), the HTTP 402 payment standard for agents, so a tool can require a stablecoin payment and an agent can settle it autonomously. It's opt-in and carries no crypto in the framework: verification is delegated to a pluggable facilitator (Coinbase, Alchemy, self-hosted), so Base and Solana are just different facilitators.
+> **Note:** `micro run` and `micro server` use a unified gateway architecture. See [Gateway Architecture](cmd/micro/README.md#gateway-architecture) for details.
 
 ```bash
-# Charge for tool calls at the MCP gateway (off unless you set a pay-to address)
-micro mcp serve --x402_pay_to 0xYourAddress --x402_network solana --x402_amount 10000
-# Per-tool amounts via a config file
-micro mcp serve --x402_config x402.json
+micro run                    # Gateway on :8080
+micro run --address :3000    # Custom gateway port
+micro run --no-gateway       # Services only
+micro run --env production   # Use production environment
 ```
 
-See the [Payments (x402) guide](internal/website/docs/guides/x402-payments.md).
+### Configuration
 
-### Reachable by other agents (A2A)
-
-Within a Go Micro system, agents reach each other over RPC. To make them reachable by agents on *other* frameworks, Go Micro speaks the [Agent2Agent (A2A) protocol](https://a2a-protocol.org). The A2A gateway discovers your agents from the registry, generates an Agent Card for each from its metadata — the same way the MCP gateway derives tools from service endpoints — and translates incoming A2A tasks to the agent's `Agent.Chat` RPC. No per-agent code: register an agent and it's reachable over A2A.
-
-```bash
-micro a2a serve --address :4000    # gateway: expose every registered agent over A2A
-micro a2a list                     # agents and their Agent Card URLs
-```
-
-Or skip the gateway entirely — an agent can serve its own A2A endpoint directly, handling tasks in-process:
-
-```go
-micro.NewAgent("task-mgr", micro.AgentServices("task"), micro.AgentA2A(":4000"))
-```
-
-It works both ways. To call an agent on another framework, an `a2a.Client` is wired into the two places that hand off work: `flow.A2A(url)` as a workflow step (the cross-framework `Dispatch`), and `delegate` to an `http(s)` URL from inside an agent.
-
-MCP exposes your services as tools; A2A exposes your agents as agents. See the [A2A guide](internal/website/docs/guides/a2a-protocol.md).

-## Features
-
-### AI
-
-| Feature | Details |
-|---------|---------|
-| Agents | `micro.NewAgent()` — intelligent layer that manages services |
-| Plan & delegate | Built-in agent tools — plan multi-step work, delegate subtasks to other agents |
-| Pluggable memory | Durable store-backed conversation memory by default; swap with `AgentMemory` |
-| Custom tools | `AgentTool` — give an agent any function as a tool, beyond its services |
-| Guardrails | `MaxSteps` (stop on count), `LoopLimit` (stop repeated no-progress calls), `ApproveTool` (human-in-the-loop) |
-| Tool middleware | `AgentWrapTool` — wrap tool execution for logging, metrics, or retries (like client/server wrappers) |
-| Workflows | `micro.NewFlow()` — event-driven; one step, ordered durable steps, or triggers an agent |
-| Durable execution | Checkpointed flow steps survive a crash and resume where they stopped; store-backed by default, pluggable backend |
-| MCP gateway | Every endpoint is an AI tool automatically |
-| A2A gateway | Every agent is reachable over the Agent2Agent protocol; cards generated from the registry (`micro a2a`) |
-| Payments (x402) | Opt-in per-call payments for tools via the x402 standard; pluggable facilitator (Base, Solana, …) |
-| 9 LLM providers | Anthropic, OpenAI, Gemini, Groq, Mistral, Together, Atlas Cloud, MiniMax, Ollama (local + cloud) |
-| Interactive console | `micro run` includes a chat console for talking to services |
-| Service generation | `micro run --prompt` — describe a system, get running services |
-
-### Framework
-
-| Feature | Details |
-|---------|---------|
-| Service registry | mDNS (default), Consul, etcd |
-| RPC client/server | gRPC transport, load balancing, streaming |
-| Pub/sub events | NATS, RabbitMQ, HTTP broker |
-| Key-value store | File (bbolt), Postgres, NATS KV |
-| Typed model layer | CRUD + queries, SQLite/Postgres backends |
-| Everything swappable | All abstractions are Go interfaces |
-
-### Developer experience & deployment
-
-| Feature | Details |
-|---------|---------|
-| Hot reload | `micro run` watches files, rebuilds on change |
-| Templates | `micro new --template crud/pubsub/api` |
-| One-command deploy | `micro deploy user@server` — SSH + systemd, no Docker |
-
-## CLI
-
-| Command | Purpose |
-|---------|---------|
-| `micro run --prompt "..."` | Generate services + agent, start with interactive console |
-| `micro run` | Dev mode: hot reload, gateway, interactive console |
-| `micro run -d` | Detached mode (no console) |
-| `micro chat` | Standalone chat (when not using micro run) |
-| `micro agent list` | List registered agents |
-| `micro new myservice` | Scaffold a service |
-| `micro call service endpoint '{}'` | Call a service or agent from the CLI |
-| `micro build` | Compile production binaries |
-| `micro deploy user@server` | Deploy via SSH + systemd |
-
-## Multi-Service Projects
-
-Run multiple services together:
-
-```go
-users := micro.NewService("users", micro.Address(":9001"))
-orders := micro.NewService("orders", micro.Address(":9002"))
-
-users.Handle(new(Users))
-orders.Handle(new(Orders))
-
-g := micro.NewGroup(users, orders)
-g.Run()
-```
-
-Or use a `micro.mu` config file:
+For multi-service projects, create a `micro.mu` file:
 
 ```
 service users
     path ./users
+    port 8081
 
-service orders
-    path ./orders
+service posts
+    path ./posts
+    port 8082
     depends users
+
+env development
+    DATABASE_URL sqlite://./dev.db
 ```
 
-## Data Model
+The gateway runs on :8080 by default, so services should use other ports.
 
-Typed persistence with CRUD and queries:
+### Deployment
 
-```go
-type User struct {
-    ID    string `json:"id" model:"key"`
-    Name  string `json:"name"`
-    Email string `json:"email" model:"index"`
-}
+Deploy to any Linux server with systemd:
 
-db := service.Model()
-db.Register(&User{})
-db.Create(ctx, &User{ID: "1", Name: "Alice", Email: "alice@example.com"})
+```bash
+# On your server (one-time setup)
+curl -fsSL https://go-micro.dev/install.sh | sh
+sudo micro init --server
 
-var results []*User
-db.List(ctx, &results, model.Where("email", "alice@example.com"))
+# From your laptop
+micro deploy user@your-server
 ```
 
-Backends: memory (default), SQLite, Postgres.
+The deploy command:
+1. Builds binaries for Linux
+2. Copies via SSH to the server
+3. Sets up systemd services
+4. Verifies services are healthy
 
-## AI Providers
+Optionally run `micro server` on the deployed machine for a production web dashboard with JWT auth, user management, and API explorer.
 
-Swap providers with a single import — same interface everywhere:
-
-| Provider | Default Model |
-|----------|---------------|
-| Anthropic | `claude-sonnet-4-20250514` |
-| OpenAI | `gpt-4o` |
-| Google Gemini | `gemini-2.5-flash` |
-| Groq | `llama-3.3-70b-versatile` |
-| Mistral | `mistral-large-latest` |
-| Together AI | `meta-llama/Llama-3.3-70B-Instruct-Turbo` |
-| Atlas Cloud | `deepseek-ai/DeepSeek-V3-0324` |
-| MiniMax | `MiniMax-M3` |
-| Ollama | `llama3.2` (local) |
-
-```go
-m := ai.New("anthropic", ai.WithAPIKey(key))
-resp, _ := m.Generate(ctx, &ai.Request{Prompt: "hello"})
+Manage deployed services:
+```bash
+micro status --remote user@server    # Check status
+micro logs --remote user@server      # View logs
+micro logs myservice --remote user@server -f  # Follow specific service
 ```

 # Go Micro Roadmap
 
-Go Micro is an **agent harness** and service framework for Go. A harness is the
-runtime around an agent — the tools, memory, guardrails, workflows, state,
-discovery, and protocols it needs to operate a system rather than just answer a
-prompt. An agent is a distributed system — it discovers services, calls them,
-holds state, and recovers from failure — so the harness is the runtime services
-already have, and building an agent is building a service. The roadmap has two
-jobs: make **agentic development** excellent, and make the **developer experience**
-around it excellent.
+This roadmap outlines the planned features and improvements for Go Micro. Community feedback and contributions are welcome!
 
-The full, current roadmap lives at **[go-micro.dev/docs/roadmap](https://go-micro.dev/docs/roadmap)**
-([source](internal/website/docs/roadmap.md)). The highlights:
+> **🚀 NEW:** See [ROADMAP_2026.md](ROADMAP_2026.md) for the **AI-Native Era roadmap** focused on MCP integration, agent-first development, and business sustainability. This document covers general framework improvements.
 
-## Where we are (v6)
+## Current Focus (Q1 2026)
 
-Services, agents (`plan`/`delegate`, guardrails, memory, tool middleware), durable
-flows, the MCP and A2A gateways (both directions, including A2A streaming,
-push notifications, and multi-turn continuation), x402 paid tools, secure by
-default.
+### Documentation & Developer Experience
+- [x] Modernize documentation structure
+- [x] Add learn-by-example guides
+- [x] Update issue templates
+- [ ] Create video tutorials
+- [ ] Interactive documentation site
+- [ ] Plugin discovery dashboard
 
-## Principles
+### Observability
+- [ ] OpenTelemetry native support
+- [ ] Auto-instrumentation for handlers
+- [ ] Metrics export standardization
+- [ ] Distributed tracing examples
+- [ ] Integration with popular observability platforms
 
-1. Build into what people run, never a separate product (no hosted platform, no
-   enterprise edition, no VC).
-2. CLI-first — the CLI is the experience; UI must earn its place, never bloat.
-3. The getting-started flow is a contract: *0→1* (scaffold → run → call) and
-   *0→hero* (a working multi-agent system) must always work and are verified on
-   every change.
-4. Interaction matters as much as running — chatting with agents, inspecting runs
-   and history, end to end.
-5. Battle-tested: works across every provider, fails safely, observable.
+### Developer Tools
+- [ ] `micro dev` with hot reload
+- [ ] Service templates (`micro new --template`)
+- [ ] Better error messages with suggestions
+- [ ] Debug tooling improvements
+- [ ] VS Code extension for Go Micro
 
-## Now — hardening
+## Q2 2026
 
-- **Cross-provider conformance** — the same agent scenario across all seven
-  providers, gated on keys, on a schedule.
-- **Failure & resilience** — timeouts, rate limits, cancellation, deadline/context
-  propagation, retry/backoff.
-- **Getting-started contract** — define and CI-verify the 0→1 and 0→hero flows.
+### Production Readiness
+- [ ] Health check standardization
+- [ ] Graceful shutdown improvements
+- [ ] Resource cleanup best practices
+- [ ] Load testing framework integration
+- [ ] Performance benchmarking suite
 
-## Next — agentic depth
+### Cloud Native
+- [ ] Kubernetes operator
+- [ ] Helm charts for common setups
+- [ ] Service mesh integration guides (Istio, Linkerd)
+- [ ] Cloud provider quickstarts (AWS, GCP, Azure)
+- [ ] Multi-cluster patterns
 
-- **Durable agent loop** — resume a long run via `Checkpoint` (flows already do).
-- **Streaming** — broaden provider-backed `ai.Stream` coverage and keep chat/A2A streaming end to end.
-- **Agent observability** — `RunInfo` → OpenTelemetry spans.
+### Security
+- [ ] mTLS by default option
+- [ ] Secret management integration (Vault, AWS Secrets Manager)
+- [ ] RBAC improvements
+- [ ] Security audit and hardening
+- [ ] CVE scanning and response process
 
-## Later
+## Q3 2026
 
-- Memory management (summarization, retrieval/RAG); human-in-the-loop pause/resume;
-  richer A2A live-stream reconnection (`tasks/resubscribe`) and `input-required`
-  handoffs.
+### Plugin Ecosystem
+- [ ] Plugin marketplace/registry
+- [ ] Plugin quality standards
+- [ ] Community plugin contributions
+- [ ] Plugin compatibility matrix
+- [ ] Auto-discovery of available plugins
 
-## Developer experience (ongoing)
+### Streaming & Async
+- [ ] Improved streaming support
+- [ ] Server-sent events (SSE) support
+- [ ] WebSocket plugin
+- [ ] Event sourcing patterns
+- [ ] CQRS examples
 
-- A seamless CLI inner loop (scaffold → run → chat → inspect → deploy); UI
-  discipline (trim what isn't great); a maintained real-world example that doubles
-  as the 0→hero reference; docs kept in lockstep with the code.
+### Testing
+- [ ] Mock generation tooling
+- [ ] Integration test helpers
+- [ ] Contract testing support
+- [ ] Chaos engineering examples
+- [ ] E2E testing framework
 
-## How it's sustained
+## Q4 2026
 
-The framework is the product, funded by sponsorship from those who run it — not a
-hosted service, enterprise tier, or venture funding. See
-[the v6 story](https://go-micro.dev/blog/27).
+### Performance
+- [ ] Connection pooling optimizations
+- [ ] Zero-allocation paths
+- [ ] gRPC performance improvements
+- [ ] Caching strategies guide

+# Go Micro Roadmap 2026: The AI-Native Era
+
+**Last Updated:** February 2026
+
+## Executive Summary
+
+The emergence of AI agents represents a **paradigm shift** in how services are consumed. Where APIs served apps, **MCP serves agents**. Go Micro is uniquely positioned to become the **standard microservices framework for the agent era**.
+
+This roadmap outlines Go Micro's evolution from an API-first framework to an **AI-native platform** while maintaining backward compatibility and ensuring long-term sustainability.
+
+---
+
+## The Paradigm Shift
+
+### Before: Apps → API Gateway → Services
+```
+┌──────────┐     HTTP/REST      ┌─────────────┐     RPC      ┌──────────┐
+│  Mobile  │ ───────────────→   │   Gateway   │ ─────────→   │ Services │
+│   App    │                    │  (Express)  │              │          │
+└──────────┘                    └─────────────┘              └──────────┘
+```
+
+Characteristics:
+- Apps need HTTP/REST/GraphQL
+- Manual API design (OpenAPI specs)
+- Developers write integration code
+- Static endpoint documentation
+
+### Now: Agents → MCP → Services
+```
+┌──────────┐      MCP/SSE       ┌─────────────┐     RPC      ┌──────────┐
+│  Claude  │ ───────────────→   │     MCP     │ ─────────→   │ Services │
+│   GPT    │                    │   Gateway   │              │          │
+└──────────┘                    └─────────────┘              └──────────┘
+```
+
+Characteristics:
+- Agents discover tools automatically
+- No manual API design needed
+- Agents write their own integration code
+- Dynamic tool discovery
+
+### Why This Matters
+
+**API Gateways solve integration for developers.**
+**MCP solves integration for AI.**
+
+Go Micro's MCP integration means:
+1. **Zero integration work** - Services become AI-accessible instantly
+2. **No API wrappers** - Agents call services directly
+3. **Dynamic discovery** - New services = new tools automatically
+4. **Natural language interface** - No documentation needed
+
+---
+
+## Strategic Vision
+
+### Mission Statement
+
+> **Make every microservice AI-native by default.**
+
+### 2026-2027 Goals
+
+1. **MCP becomes the default** - `micro run` enables MCP automatically
+2. **Best-in-class agent integration** - The easiest way to expose services to AI
+3. **Sustainable business model** - Open core with premium offerings
+4. **Production deployment at scale** - 1000+ services running MCP gateways
+5. **Ecosystem leadership** - The go-to framework when AI needs microservices
+
+---
+
+## Roadmap
+
+## Q1 2026: MCP Foundation ✅ COMPLETE
+
+**Status:** COMPLETE as of February 2026
+
+### Delivered
+- [x] MCP library (`gateway/mcp`)
+- [x] CLI integration (`micro run --mcp-address`)
+- [x] Service discovery and tool generation
+- [x] HTTP/SSE transport
+- [x] Documentation and examples
+- [x] Blog post and launch
+
+### Impact
+- Services are now AI-accessible with 3 lines of code
+- Both library and CLI users can use MCP
+- Foundation for agent-first development
+
+---
+
+## Q2 2026: Agent Developer Experience
+
+**Status:** IN PROGRESS - Several features delivered early (Feb 2026)
+
+**Theme:** Make it trivial for any AI to call your services
+
+### MCP Enhancements
+
+#### Stdio Transport for Claude Code ✅ COMPLETE (delivered early)
+- [x] Implement stdio JSON-RPC protocol
+- [x] Auto-detection: stdio vs HTTP based on environment
+- [x] `micro mcp` command for Claude Code integration
+- [x] Example: Add go-micro services to Claude Code
+
+**Why:** Claude Code and other local AI tools use stdio MCP servers. This enables:
+```bash
+# In Claude Code config
+{
+  "mcpServers": {
+    "my-services": {
+      "command": "micro",
+      "args": ["mcp"]
+    }
+  }
+}
+```
+
+**Business value:** Direct integration with Anthropic's flagship developer tool.
+
+#### Tool Descriptions from Comments ✅ COMPLETE (delivered early)
+- [x] Parse Go comments to generate tool descriptions
+- [x] Support JSDoc-style tags: `@param`, `@return`, `@example`
+- [x] Schema generation from struct tags
+- [ ] Auto-generate examples from test cases
+
+**Before:**
+```
+Tools:
+- users.Users.Get - Call Get on users service
+```
+
+**After:**
+```
+Tools:
+- users.Users.Get
+  Description: Retrieve user profile by ID. Returns full profile including email,
+               name, created date, and preferences.
+  Parameters:
+    - id (string, required): User ID in UUID format
+  Returns: User object with profile fields
+  Example: {"id": "123e4567-e89b-12d3-a456-426614174000"}
+```
+
+**Why:** Better descriptions = better agent performance. Agents need context to call services correctly.
+
+#### Multi-Protocol Support
+- [ ] WebSocket transport for streaming
+- [ ] gRPC reflection for MCP (bidirectional streaming)
+- [x] Server-Sent Events with auth (HTTP/SSE implemented)
+- [ ] HTTP/3 support
+
+**Why:** Different agents prefer different protocols. Support them all.
+
+### Agent SDKs
+
+Create official SDKs for popular agent frameworks:

+## Q3 2026: Production & Scale
+
+**Status:** IN PROGRESS - Core security features delivered early (Feb 2026)
+
+**Theme:** Run MCP gateways in production at scale
+
+### Enterprise MCP Gateway
+
+Create a production-grade standalone MCP gateway:
+
+#### Gateway Features
+- [ ] Standalone binary: `micro-mcp-gateway`
+- [ ] Horizontal scaling (stateless design)
+- [x] Rate limiting per agent/token ✅ (delivered early)
+- [ ] Usage tracking and analytics
+- [x] Cost attribution (track which agent called what) ✅ (audit logging)
+- [ ] Circuit breakers for service protection
+- [ ] Request/response caching
+- [ ] Multi-tenant support (isolate services by namespace)
+
+**Deployment:**
+```bash
+# Standalone gateway
+micro-mcp-gateway \
+  --registry consul:8500 \
+  --address :3000 \
+  --auth jwt \
+  --rate-limit 1000/hour \
+  --cache redis:6379
+```
+
+**Business value:** Enterprise customers need production-grade MCP gateways. This is a **paid offering**.
+
+#### Observability
+- [ ] OpenTelemetry integration
+- [x] Agent call tracing (which agent called what) ✅ (trace IDs implemented)
+- [ ] Tool usage metrics (which tools are popular)
+- [ ] Performance dashboards
+- [ ] Anomaly detection (unusual agent behavior)
+- [ ] Cost analysis (cloud spend per agent)
+
+**Dashboard Example:**
+```
+Agent Activity - Last 7 Days
+─────────────────────────────
+Claude Desktop    1,234 calls   $12.34 compute cost
+ChatGPT Plugin    567 calls     $5.67 compute cost
+Custom Agent      234 calls     $2.34 compute cost
+
+Top Services
+────────────
+users    45%
+orders   30%
+payments 15%
+
+Slowest Tools
+─────────────
+analytics.Reports.Generate   2.3s avg
+payments.Payments.Process    890ms avg
+```
+
+**Business value:** Enterprises need observability. This justifies MCP Gateway pricing.
+
+### Security ✅ CORE FEATURES COMPLETE (delivered early)
+
+#### Agent Authentication ✅ COMPLETE
+- [x] Auth provider integration (auth.Auth)
+- [x] Bearer token authentication
+- [x] Scope-based permissions (agent can only call certain services)
+- [x] Audit logging (full trail of what agents accessed)
+- [ ] OAuth2 for agent authorization (basic auth implemented)
+- [ ] API keys per agent (bearer tokens supported)
+
+**Implemented Example:**
+```go
+mcp.Serve(mcp.Options{
+    Registry: registry,
+    Auth:     authProvider,  // ✅ Implemented
+    Scopes: map[string][]string{  // ✅ Implemented
+        "blog.Blog.Create": {"blog:write"},
+        "blog.Blog.Delete": {"blog:admin"},
+    },
+    AuditFunc: func(r mcp.AuditRecord) {  // ✅ Implemented
+        log.Printf("[audit] %+v", r)
+    },
+})
+```
+
+#### Service-Side Authorization ✅ COMPLETE
+- [x] Services can validate which agent is calling
+- [x] Agent identity in context (via metadata)
+- [x] Fine-grained permissions (Agent X can read but not write)
+- [x] Trace ID propagation for debugging
+
+**Implemented - Metadata in Context:**
+```go
+// Trace ID, Tool Name, and Account ID are automatically
+// propagated to services via context metadata:
+// - Mcp-Trace-Id
+// - Mcp-Tool-Name  
+// - Mcp-Account-Id
+```
+
+**Future Enhancement - Service-Side Example:**
+```go
+// Future: Direct access to agent info from context
+func (s *Users) Delete(ctx context.Context, req *Request, rsp *Response) error {
+    // For now, services can read metadata keys:
+    // Mcp-Account-Id, Mcp-Trace-Id, Mcp-Tool-Name
+    md, _ := metadata.FromContext(ctx)
+    accountID := md["Mcp-Account-Id"]
+    
+    if accountID != "admin-account" {
+        return errors.Forbidden("users", "admin only")
+    }
+    // ...
+}
+```
+
+**Business value:** Security is a hard requirement for enterprise adoption.
+
+### Deployment Patterns
+
+#### Kubernetes Operator
+- [ ] `micro-operator` for Kubernetes

+## Risk Mitigation
+
+### Technical Risks
+
+**Risk:** MCP protocol changes (Anthropic controls spec)
+- **Mitigation:** Stay involved in MCP working group, implement protocol versions
+
+**Risk:** Performance issues at scale
+- **Mitigation:** Benchmark early, optimize hot paths, use caching aggressively
+
+**Risk:** Security vulnerabilities in MCP gateway
+- **Mitigation:** Security audits, bug bounty program, responsible disclosure
+
+### Business Risks
+
+**Risk:** AI hype dies down
+- **Mitigation:** Go Micro still works as regular microservices framework. MCP is additive, not core.
+
+**Risk:** Competitors build MCP support
+- **Mitigation:** First-mover advantage, best integration, agent marketplace moat
+
+**Risk:** Cloud providers offer competing solutions
+- **Mitigation:** Open source = no vendor lock-in. We're the community choice.
+
+### Market Risks
+
+**Risk:** Enterprises slow to adopt agents
+- **Mitigation:** Focus on startups first (faster adoption), build proof points
+
+**Risk:** Different MCP implementations fragment market
+- **Mitigation:** Support multiple protocols, be the most compatible
+
+---
+
+## Competitive Landscape
+
+### Direct Competitors
+- **Spring Boot** - Java, no MCP support (yet)
+- **Express.js** - JavaScript, minimal microservices support
+- **gRPC-based frameworks** - No MCP support
+
+**Our advantage:** First-mover in MCP + microservices space.
+
+### Indirect Competitors
+- **API Gateway vendors** (Kong, Tyk) - Could add MCP support
+- **Service meshes** (Istio, Linkerd) - Focus on ops, not AI
+
+**Our advantage:** Purpose-built for agent integration, not retrofitted.
+
+### Potential Threats
+- **AWS/GCP/Azure** building managed MCP gateways
+- **Anthropic** launching their own microservices framework
+
+**Defense:**
+- Open source = community ownership
+- Best DX (developer experience)
+- Agent marketplace = network effects

-# AI Package
-
-The `ai` package provides simple, high-level interfaces for AI model providers. It supports text generation (`Model`), image generation (`ImageModel`), and video generation (`VideoModel`).
-
-## Interfaces
-
-### Text Generation (Model)
-
-The Model interface follows the same patterns as other go-micro packages (Registry, Client, Broker):
-
-```go
-type Model interface {
-    Init(...Option) error
-    Options() Options
-    Generate(ctx context.Context, req *Request, opts ...GenerateOption) (*Response, error)
-    Stream(ctx context.Context, req *Request, opts ...GenerateOption) (Stream, error)
-    String() string
-}
-```
-
-## Quick Start
-
-```go
-import (
-    "context"
-    "go-micro.dev/v5/ai"
-    _ "go-micro.dev/v5/ai/anthropic"
-    _ "go-micro.dev/v5/ai/openai"
-)
-
-// Create a model
-m := ai.New("openai",
-    ai.WithAPIKey("your-api-key"),
-    ai.WithModel("gpt-4o"),
-)
-
-// Generate a response
-req := &ai.Request{
-    Prompt:       "What is Go?",
-    SystemPrompt: "You are a helpful programming assistant",
-}
-
-resp, err := m.Generate(context.Background(), req)
-if err != nil {
-    log.Fatal(err)
-}
-
-fmt.Println(resp.Reply)
-```
-
-### Image Generation (ImageModel)
-
-```go
-type ImageModel interface {
-    GenerateImage(ctx context.Context, req *ImageRequest, opts ...GenerateOption) (*ImageResponse, error)
-    String() string
-}
-```
-
-```go
-import (
-    "go-micro.dev/v5/ai"
-    _ "go-micro.dev/v5/ai/atlascloud"
-)
-
-ig := ai.NewImage("atlascloud",
-    ai.WithAPIKey("your-api-key"),
-)
-
-resp, err := ig.GenerateImage(context.Background(), &ai.ImageRequest{
-    Prompt: "A Go gopher in space",
-    Size:   "1024x1024",
-})
-
-fmt.Println(resp.Images[0].URL)
-```
-
-Providers that support image generation: **Atlas Cloud**, **OpenAI**.
-
-### Video Generation (VideoModel)
-
-```go
-type VideoModel interface {
-    GenerateVideo(ctx context.Context, req *VideoRequest, opts ...GenerateOption) (*VideoResponse, error)
-    String() string
-}
-```
-
-```go
-import (
-    "go-micro.dev/v5/ai"
-    _ "go-micro.dev/v5/ai/atlascloud"
-)
-
-vg := ai.NewVideo("atlascloud",
-    ai.WithAPIKey("your-api-key"),
-)
-
-resp, err := vg.GenerateVideo(context.Background(), &ai.VideoRequest{
-    Prompt:   "Microservices nodes animating with data flowing between them",
-    Images:   []string{"https://example.com/diagram.png"}, // optional: image-to-video
-    Duration: 6,
-})
-
-fmt.Println(resp.URL)
-```
-
-Providers that support video generation: **Atlas Cloud**.
-
-## Options
-
-Configure the model using functional options:
-
-```go
-m := ai.New("anthropic",
-    ai.WithAPIKey("your-key"),              // Required
-    ai.WithModel("claude-sonnet-4-20250514"), // Optional, uses provider default
-    ai.WithBaseURL("https://api.anthropic.com"), // Optional, uses provider default
-)
-```
-
-You can also update options after creation:
-
-```go
-m.Init(
-    ai.WithModel("gpt-4o-mini"),
-    ai.WithAPIKey("new-key"),
-)
-```
-
-## Using Tools
-
-The model can automatically execute tool calls when provided with a tool handler:
-
-```go
-// Define a tool handler. It mirrors a go-micro RPC handler: context
-// first, the call in, a result out.
-toolHandler := func(ctx context.Context, call ai.ToolCall) ai.ToolResult {
-    // Execute the tool and return results
-    switch call.Name {
-    case "get_weather":
-        return ai.ToolResult{ID: call.ID, Value: map[string]string{"temp": "72F"}, Content: `{"temp": "72F"}`}
-    default:
-        return ai.ToolResult{ID: call.ID, Content: `{"error": "unknown tool"}`}
-    }
-}
-
-// Create model with tool handler
-m := ai.New("openai",
-    ai.WithAPIKey("your-key"),
-    ai.WithToolHandler(toolHandler),
-)
-
-// Provide tools in the request
-req := &ai.Request{
-    Prompt: "What's the weather?",
-    SystemPrompt: "You are a helpful assistant",
-    Tools: []ai.Tool{
-        {
-            Name:        "get_weather",
-            Description: "Get current weather",
-            Properties: map[string]any{
-                "location": map[string]any{
-                    "type": "string",
-                    "description": "City name",
-                },
-            },
-        },
-    },
-}
-
-// Generate will automatically call tools and return final answer
-resp, err := m.Generate(context.Background(), req)
-fmt.Println(resp.Answer) // Final answer after tool execution
-```
-
-## Response Structure
-
-```go
-type Response struct {
-    Reply     string      // Initial reply from model
-    ToolCalls []ToolCall  // Tools the model wants to call
-    Answer    string      // Final answer (after tool execution if handler provided)
-}
-```
-
-- `Reply`: The model's first response
-- `ToolCalls`: List of tools the model requested (if any)
-- `Answer`: The final answer after tools are executed (only set if ToolHandler is provided)
-
-## Provider capability matrix
-
-The CLI can print the provider capabilities registered in the current build:
-
-```bash
-micro ai providers
-```
-
-For automation and docs generation, emit the same matrix as stable JSON:
-
-```bash
-micro ai providers --json
-```
-
-It reports support from Go Micro's provider registry, so the matrix reflects the model, image, and video interfaces available to this binary rather than external provider marketing claims.
-

-
-## Auto-Detection
-
-Use `AutoDetectProvider()` to detect the provider from a base URL:
-
-```go
-provider := ai.AutoDetectProvider("https://api.anthropic.com")
-// Returns "anthropic"
-
-m := ai.New(provider, ai.WithAPIKey("..."))
-```
-
-## Adding a New Provider
-
-See the full **[AI Provider Integration Guide](../internal/website/docs/guides/ai-provider-guide.md)** for a step-by-step walkthrough, checklist, and design notes.
-
-Quick summary:
-
-1. Create `ai/yourprovider/yourprovider.go` implementing `ai.Model`.
-2. Call `ai.Register("yourprovider", ...)` in `init()`.
-3. Add tests in `ai/yourprovider/yourprovider_test.go`.
-4. Users enable the provider with a blank import:
-
-```go
-import _ "go-micro.dev/v5/ai/yourprovider"
-```
-
-We welcome contributions and sponsorships from AI infrastructure companies — see the guide for details.
-
-## Comparison with Other Packages
-
-The ai package follows the same patterns as other go-micro packages:
-
-**Registry:**
-```go
-r := registry.NewRegistry(registry.Addrs("..."))
-r.Register(service)
-```
-
-**Client:**
-```go
-c := client.NewClient(client.Retries(3))
-c.Call(ctx, req, rsp)
-```
-
-**AI:**
-```go
-m := ai.New("openai", ai.WithAPIKey("..."))
-m.Generate(ctx, req)
-```
-
-All use:
-- `Init()` to update options
-- `Options()` to get current options
-- `String()` to get the implementation name
-- Functional options pattern
-
-## Testing
-
-```bash
-go test ./ai/...
-```
-
-## Examples
-
-See the [server implementation](../cmd/micro/server/server.go) for a complete example of using the ai package with tool execution.
