docs: rewrite Anthropic blog post with updated content and new header image (#2910)

Rewrite blog/3 to reflect current state of the project:
- Update numbers (7 providers, image/video support, micro chat)
- Add "What Came After" section covering everything shipped since
- Tighten prose, remove stale roadmap percentages
- Replace generic MCP image with Claude-themed header generated
  via Atlas Cloud (orange AI orb connecting to service nodes)
- Streamline code examples
- Update star count and Try It section

+# Changelog
+
+All notable changes to Go Micro are documented here.
+
+Format follows [Keep a Changelog](https://keepachangelog.com/). Go Micro uses
+calendar-based versions (YYYY.MM) for the AI-native era.
+
+---
+
+## [Unreleased]
+
+### Added
+- **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.New("name")` unified API** — single way to create services: `micro.New("greeter")` or `micro.New("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.New("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`).
+
+#### AI Model Package
+- **`model.Model` interface** — unified AI provider abstraction with `Generate()` and `Stream()` methods.
+- **Anthropic Claude provider** — `model/anthropic` with tool execution and auto-calling.
+- **OpenAI GPT provider** — `model/openai` with provider auto-detection from base URL.
+
+#### Agent SDKs
+- **LangChain SDK** — `contrib/langchain-go-micro/` Python package with auto-discovery, tool generation, and multi-agent workflow examples.
+- **LlamaIndex SDK** — `contrib/go-micro-llamaindex/` Python package with RAG integration examples.
+
+#### Documentation
+- **AI-native services guide** — building services for AI agents from scratch
+- **MCP security guide** — auth, scopes, and audit logging
+- **Tool descriptions guide** — writing doc comments that improve agent performance
+- **Agent patterns guide** — architecture patterns for agent integration
+- **Error handling guide** — writing agent-friendly error responses with typed errors
+- **Troubleshooting guide** — common MCP issues and solutions
+- **Migration guide** — add MCP to existing services in 5 minutes
+
+#### CLI
+- **`micro mcp serve`** — start MCP server (stdio for Claude Code, HTTP for web agents)
+- **`micro mcp list`** — list available tools (human-readable or JSON)
+- **`micro mcp test`** — test tools with JSON input
+- **`micro mcp docs`** — generate tool documentation
+- **`micro mcp export`** — export to LangChain, OpenAPI, or JSON formats
+
+#### Agent Playground
+- **Chat-focused UI** — redesigned playground with collapsible tool calls, real-time status, and thinking indicators
+- **Provider settings** — configurable OpenAI/Anthropic provider, model, and API key
+
+### Changed
+- Service interface moved to `service.Service` with `micro.Service` as a type alias for backward compatibility.
+- `service.New()` returns `service.Service` interface (was `*ServiceImpl`).
+- `service.NewGroup()` accepts `service.Service` interface (was `*ServiceImpl`).
+- `go.mod` template in `micro new` updated to Go 1.22.
+
+### Fixed
+- Handler `Handle()` method accepts variadic `server.HandlerOption` for scopes and metadata.
+- Store initialization uses service name as table automatically.
+- Service `Stop()` properly aggregates errors from lifecycle hooks.
+
+---
+
+## [2026.02] - February 2026
+
+### Added
+- **MCP gateway library** — `gateway/mcp/` with HTTP/SSE and stdio transports, service discovery, tool generation, and JSON schema generation from Go types (2,500+ lines).
+- **CLI integration** — `micro run --mcp-address` flag to start MCP alongside services.
+- **Documentation extraction** — auto-extract tool descriptions from Go doc comments with `@example` tag and struct tag parsing.
+- **Blog post** — "Making Microservices AI-Native with MCP"
+- **MCP examples** — `examples/mcp/hello/` and `examples/mcp/documented/`
+
+---
+
+## [2026.01] - January 2026
+
+### Added
+- **`micro deploy`** — deploy services to any Linux server via SSH + systemd with `micro deploy user@server`.
+- **`micro build`** — build Go binaries and Docker images with `micro build --docker`.
+- **Blog post** — "Introducing micro deploy"

+# 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
+
+# Run locally with hot reload
+micro run
+```
+

+
+## 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

 ## Features
 
 Go Micro abstracts away the details of distributed systems. Here are the main features.
 
-- **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.

-- **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.

+  level config from any source such as env vars, file, etcd. You can merge the sources and even define fallbacks.
 
-- **Data Storage** - A simple data store interface to read, write and delete records. It includes support for memory, file and 
-CockroachDB by default. State and persistence becomes a core requirement beyond prototyping and Micro looks to build that into the framework.

+in the plugins repo. State and persistence becomes a core requirement beyond prototyping and Micro looks to build that into the framework.
 
-- **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.
+- **Data Model** - A typed data model layer with CRUD operations, queries, and multiple backends (memory, SQLite, Postgres). Define Go
+  structs with tags and get type-safe Create/Read/Update/Delete/List/Count operations. Accessible via `service.Model()` alongside
+  `service.Client()` and `service.Server()` for a complete service experience: call services, handle requests, save and query data.
 
-- **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.

+  development. When service A needs to speak to service B it needs the location of that service. The default discovery mechanism is

-- **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.

-- **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.

-- **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.
+- **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.
+
+- **Multi-Service Binaries** - Run multiple services in a single process with isolated state per service. Start as a modular monolith,
+  split into separate deployments when you need independent scaling. Each service gets its own server, client, and store while sharing
+  the registry and broker for inter-service communication.

+
+## MCP & AI Agents
+
+<img src="internal/website/images/generated/mcp-agent.png" alt="AI agent calling microservices via MCP" width="100%" />
+
+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 `/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
+# Agent Playground:  http://localhost:8080/agent
+# MCP Tools:         http://localhost:8080/mcp/tools
+```
+
+Use `micro mcp serve` for local AI tools like Claude Code, or connect any MCP-compatible agent to the HTTP endpoint.
+
+### micro chat
+
+For an interactive terminal session that lets you talk to your services through an LLM:
+
+```bash
+ANTHROPIC_API_KEY=sk-ant-... micro chat --provider anthropic
+> list all users
+> create an order for product 42
+```
+
+`micro chat` discovers every service in the registry, exposes each endpoint as a tool, and lets the model orchestrate calls. The same building blocks (`ai/tools`) work from your own services:
+
+```go
+import "go-micro.dev/v5/ai/tools"
+
+set := tools.New(service.Registry())
+discovered, _ := set.Discover()
+
+m := ai.New("anthropic",
+    ai.WithAPIKey(key),
+    ai.WithToolHandler(set.Handler(service.Client())),
+)
+resp, _ := m.Generate(ctx, &ai.Request{
+    Prompt: userInput,
+    Tools:  discovered,
+})
+```
+
+See the [MCP guide](https://go-micro.dev/docs/mcp.html) for authentication, scopes, and advanced usage.
+
+## Multi-Service Binaries
+
+Run multiple services in a single binary — start as a modular monolith, split into separate deployments later when you actually need to.
+
+```go
+users := micro.New("users", micro.Address(":9001"))
+orders := micro.New("orders", micro.Address(":9002"))
+
+users.Handle(new(Users))
+orders.Handle(new(Orders))
+
+// Run all services together with shared lifecycle
+g := micro.NewGroup(users, orders)
+g.Run()
+```
+
+Each service gets its own server, client, store, and cache while sharing the registry, broker, and transport — so they can discover and call each other within the same process.
+
+See the [multi-service example](examples/multi-service/) for a working demo.
+
+## Data Model
+
+Go Micro includes a typed data model layer for persistence. Define a struct, tag a key field, and get type-safe CRUD and query operations backed by memory, SQLite, or Postgres.
+
+```go
+import (
+        "go-micro.dev/v5/model"
+        "go-micro.dev/v5/model/sqlite"
+)
+
+// Define your data type
+type User struct {
+        ID    string `json:"id" model:"key"`
+        Name  string `json:"name"`
+        Email string `json:"email" model:"index"`
+        Age   int    `json:"age"`
+}
+```
+
+Register your types and use the model:
+
+```go
+service := micro.New("users")
+
+// Register and use the service's model backend
+db := service.Model()
+db.Register(&User{})
+
+// CRUD operations
+db.Create(ctx, &User{ID: "1", Name: "Alice", Email: "alice@example.com", Age: 30})
+
+user := &User{}
+db.Read(ctx, "1", user)
+
+user.Name = "Alice Smith"
+db.Update(ctx, user)
+
+db.Delete(ctx, "1", &User{})
+```
+
+Query with filters, ordering, and pagination:
+
+```go
+var results []*User
+
+// Find users by field
+db.List(ctx, &results, model.Where("email", "alice@example.com"))
+
+// Complex queries
+db.List(ctx, &results,
+        model.WhereOp("age", ">=", 18),
+        model.OrderDesc("name"),
+        model.Limit(10),
+        model.Offset(20),
+)
+
+count, _ := users.Count(ctx, model.Where("age", 30))
+```
+
+Swap backends with an option:
+
+```go
+// Development: in-memory (default)
+service := micro.New("users")
+
+// Production: SQLite or Postgres
+db, _ := sqlite.New(model.WithDSN("file:app.db"))
+service := micro.New("users", micro.Model(db))
+```
+
+Every service gets `Client()`, `Server()`, and `Model()` — call services, handle requests, and save data all from the same interface.

+
+## Protobuf
+
+Install the code generator and see usage in the docs:
+
+```bash
+go install go-micro.dev/v5/cmd/protoc-gen-micro@v5.16.0
+```
+
+> **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.
+
+Docs: [`internal/website/docs/getting-started.md`](internal/website/docs/getting-started.md)
+
+## Command Line
+
+Install the CLI:
+
+```
+go install go-micro.dev/v5/cmd/micro@v5.16.0
+```
+
+> **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.
+
+### Quick Start
+
+```bash
+micro new helloworld   # Create a new service
+cd helloworld
+micro run              # Run with API gateway and hot reload
+```
+
+Then open http://localhost:8080 to see your service and call it from the browser.
+
+### Development Workflow
+
+| 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 |
+
+### micro run
+
+`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 `/mcp/tools`
+- **Health Checks** - Aggregated health at `/health`
+- **Hot Reload** - Auto-rebuild on file changes
+
+> **Note:** `micro run` and `micro server` use a unified gateway architecture. See [Gateway Architecture](cmd/micro/README.md#gateway-architecture) for details.
+
+```bash
+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
+```
+
+### Configuration
+
+For multi-service projects, create a `micro.mu` file:
+
+```
+service users
+    path ./users
+    port 8081
+
+service posts
+    path ./posts
+    port 8082
+    depends users
+
+env development
+    DATABASE_URL sqlite://./dev.db
+```
+
+The gateway runs on :8080 by default, so services should use other ports.
+
+### Deployment
+
+Deploy to any Linux server with systemd:
+
+```bash
+# On your server (one-time setup)
+curl -fsSL https://go-micro.dev/install.sh | sh
+sudo micro init --server
+
+# From your laptop
+micro deploy user@your-server
+```
+
+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
+
+Optionally run `micro server` on the deployed machine for a production web dashboard with JWT auth, user management, and API explorer.
+
+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
+```
+
+No Docker required. No Kubernetes. Just systemd.

+## Supported AI Providers
+
+Go Micro’s `ai` package gives every provider the same interface: `Init`, `Generate`, `Stream`, and functional options. Swap providers with a single import.
+
+| Provider | Import | Default Model |
+|----------|--------|---------------|
+| **Anthropic** | `go-micro.dev/v5/ai/anthropic` | `claude-sonnet-4-20250514` |
+| **Google Gemini** | `go-micro.dev/v5/ai/gemini` | `gemini-2.5-flash` |
+| **Groq** | `go-micro.dev/v5/ai/groq` | `llama-3.3-70b-versatile` |
+| **Mistral** | `go-micro.dev/v5/ai/mistral` | `mistral-large-latest` |
+| **OpenAI** | `go-micro.dev/v5/ai/openai` | `gpt-4o` |
+| **Together AI** | `go-micro.dev/v5/ai/together` | `Llama-3.3-70B-Instruct-Turbo` |
+| **Atlas Cloud** | `go-micro.dev/v5/ai/atlascloud` | `llama-3.3-70b` |
+
+Any provider that exposes an OpenAI-compatible API can also be used directly:
+
+```go
+m := ai.New("openai",
+    ai.WithAPIKey("your-key"),
+    ai.WithBaseURL("https://api.yourprovider.com"),
+)
+```
+
+**Want to add your platform?** See the [AI Provider Integration Guide](internal/website/docs/guides/ai-provider-guide.md) for how to implement `ai.Model` and submit a PR.

+
+## Security Best Practices
+
+When using go-micro in production:
+
+### TLS/Transport Security
+
+```go
+import "go-micro.dev/v5/transport"
+
+// Enable TLS verification (recommended)
+os.Setenv("MICRO_TLS_SECURE", "true")
+
+// Or use SecureConfig explicitly
+tlsConfig := transport.SecureConfig()
+```
+
+See [TLS Security Update](internal/website/docs/TLS_SECURITY_UPDATE.md) for details.
+
+### Authentication
+
+```go
+import "go-micro.dev/v5/auth"
+
+// Use JWT authentication
+service := micro.NewService(
+    micro.Auth(auth.NewAuth()),
+)
+```
+
+### Input Validation
+
+Always validate and sanitize inputs in your handlers:
+
+```go
+func (h *Handler) Create(ctx context.Context, req *Request, rsp *Response) error {
+    // Validate input
+    if req.Name == "" {
+        return errors.BadRequest("handler.create", "name is required")
+    }
+    
+    // Sanitize and process
+    // ...
+}
+```
+
+### Rate Limiting
+
+Implement rate limiting for public-facing services:
+
+```go
+import "go-micro.dev/v5/client"
+
+// Client-side rate limiting
+client.NewClient(
+    client.RequestTimeout(time.Second * 5),
+    client.Retries(3),
+)
+```
+
+### Secrets Management
+
+Never commit secrets to version control:
+
+```go
+// Good: Use environment variables
+apiKey := os.Getenv("API_KEY")
+
+// Better: Use a secrets manager
+import "github.com/hashicorp/vault/api"
+```
+
+### Dependency Security
+
+Regularly update dependencies:
+
+```bash
+# Check for vulnerabilities
+go list -json -m all | nancy sleuth
+
+# Update dependencies
+go get -u ./...
+go mod tidy
+```
+
+## Known Security Considerations
+
+### Reflection Usage
+
+go-micro uses reflection for automatic handler registration. While this is a deliberate design choice for developer productivity, be aware:
+
+- Type safety is enforced at runtime, not compile time
+- Malformed requests won't crash services (errors are returned)
+- See [Performance Considerations](internal/website/docs/performance.md)
+
+### TLS Certificate Verification
+
+**Default behavior in v5**: TLS certificate verification is **disabled** for backward compatibility.
+
+**Production recommendation**: Enable secure mode:
+
+```bash
+export MICRO_TLS_SECURE=true
+```
+
+This will be the default in v6.
+
+## Security Updates
+
+Security updates are published as:
+- GitHub Security Advisories
+- Release notes with `[SECURITY]` prefix
+- CVE entries for critical issues
+
+Subscribe to releases: https://github.com/micro/go-micro/releases
+
+## Bug Bounty
+
+We currently do not offer a bug bounty program, but we greatly appreciate responsible disclosure and will publicly credit researchers who report valid security issues.
+
+## Questions?

+For security questions that are not vulnerabilities, please:
+- Open a discussion: https://github.com/micro/go-micro/discussions
+- Join Discord: https://discord.gg/jwTYuUVAGh

+# 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
+toolHandler := func(name string, input map[string]any) (result any, content string) {
+    // Execute the tool and return results
+    switch name {
+    case "get_weather":
+        return map[string]string{"temp": "72F"}, `{"temp": "72F"}`
+    default:
+        return nil, `{"error": "unknown tool"}`
+    }
+}
+
+// Create model with tool handler
+m := ai.New("openai",
+    ai.WithAPIKey("your-key"),
+    ai.WithToolHandler(toolHandler),
+)
+

+- `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)
+
+## Supported Providers
+
+### Anthropic Claude
+
+```go
+m := ai.New("anthropic",
+    ai.WithAPIKey("sk-ant-..."),
+    ai.WithModel("claude-sonnet-4-20250514"), // default
+)
+```
+
+Default model: `claude-sonnet-4-20250514`
+Default base URL: `https://api.anthropic.com`
+
+### OpenAI GPT
+
+```go
+m := ai.New("openai",
+    ai.WithAPIKey("sk-..."),
+    ai.WithModel("gpt-4o"), // default
+)
+```
+
+Default model: `gpt-4o`
+Default base URL: `https://api.openai.com`

+### Google Gemini
+
+```go
+m := ai.New("gemini",
+    ai.WithAPIKey("your-key"),
+    ai.WithModel("gemini-2.5-flash"), // default
+)
+```
+
+Default model: `gemini-2.5-flash`
+Default base URL: `https://generativelanguage.googleapis.com`
+
+Google Gemini uses its own API format with `system_instruction`, `contents` (not `messages`), and `functionDeclarations` for tool calling. The provider handles the translation automatically.
+
+### Groq
+
+```go
+m := ai.New("groq",
+    ai.WithAPIKey("your-key"),
+    ai.WithModel("llama-3.3-70b-versatile"), // default
+)
+```
+
+Default model: `llama-3.3-70b-versatile`
+Default base URL: `https://api.groq.com/openai`
+
+Groq provides ultra-fast inference for open-weight models via an OpenAI-compatible endpoint.
+
+### Mistral
+
+```go
+m := ai.New("mistral",
+    ai.WithAPIKey("your-key"),
+    ai.WithModel("mistral-large-latest"), // default
+)
+```
+
+Default model: `mistral-large-latest`
+Default base URL: `https://api.mistral.ai`
+
+Mistral AI is a European AI company offering high-performance models via an OpenAI-compatible endpoint.
+
+### Together AI
+
+```go
+m := ai.New("together",
+    ai.WithAPIKey("your-key"),
+    ai.WithModel("meta-llama/Llama-3.3-70B-Instruct-Turbo"), // default
+)
+```
+
+Default model: `meta-llama/Llama-3.3-70B-Instruct-Turbo`
+Default base URL: `https://api.together.xyz`
+
+Together AI provides fast inference for open-weight models via an OpenAI-compatible endpoint.
+
+### Atlas Cloud
+
+```go
+m := ai.New("atlascloud",
+    ai.WithAPIKey("your-key"),
+    ai.WithModel("llama-3.3-70b"), // default
+)
+```
+
+Default model: `llama-3.3-70b`
+Default base URL: `https://api.atlascloud.ai`
+
+Atlas Cloud is an enterprise AI infrastructure platform offering high-performance LLM APIs. It exposes an OpenAI-compatible chat completions endpoint with tool calling support.
+
+## 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.

+# Auth Package Analysis
+
+## Current Status: ✅ Fully Functional
+
+The auth package is now **production-ready** with complete server/client wrappers and integration examples.
+
+---
+
+## ✅ What Exists
+
+### 1. Core Interfaces (`auth.go`)
+
+```go
+type Auth interface {
+    Generate(id string, opts ...GenerateOption) (*Account, error)
+    Inspect(token string) (*Account, error)
+    Token(opts ...TokenOption) (*Token, error)
+}
+
+type Rules interface {
+    Verify(acc *Account, res *Resource, opts ...VerifyOption) error
+    Grant(rule *Rule) error
+    Revoke(rule *Rule) error
+    List(...ListOption) ([]*Rule, error)
+}
+```
+
+**Status:** ✅ Well-designed, complete
+
+### 2. Data Types
+
+- `Account` - represents authenticated user/service
+- `Token` - access/refresh token pair
+- `Resource` - service endpoint to protect
+- `Rule` - access control rule
+- `Access` - grant/deny enum
+
+**Status:** ✅ Complete
+
+### 3. Implementations
+
+**Noop Auth** (`noop.go`):
+- For development/testing
+- Always grants access
+- No actual authentication
+
+**Status:** ✅ Works for dev
+
+**JWT Auth** (`jwt/jwt.go`):
+- Uses RSA keys for signing
+- Generates and verifies JWT tokens
+- **⚠️ Problem:** Depends on external plugin `github.com/micro/plugins/v5/auth/jwt/token`
+
+**Status:** ⚠️ External dependency
+
+### 4. Authorization Logic (`rules.go`)
+
+- Rule-based access control (RBAC)
+- Supports wildcards (`*`)
+- Priority-based rule evaluation
+- Scope-based permissions
+
+**Status:** ✅ Complete and tested
+
+---
+
+## ✅ Recently Completed
+
+### 1. **Service Integration Wrapper** ✅
+
+**Status:** IMPLEMENTED in `wrapper/auth/server.go`
+
+```go
+// AuthHandler wraps a service to enforce authentication
+func AuthHandler(opts HandlerOptions) server.HandlerWrapper
+func PublicEndpoints(...) HandlerOptions
+func AuthRequired(...) HandlerOptions
+func AuthOptional(authProvider auth.Auth) server.HandlerWrapper
+```
+
+Features:
+- Token extraction from metadata
+- Token verification with auth.Inspect()
+- Authorization checks with rules.Verify()
+- Account injection into context
+- Skip endpoints support
+- Comprehensive error handling (401/403)
+
+### 2. **Client Wrapper** ✅
+
+**Status:** IMPLEMENTED in `wrapper/auth/client.go`
+
+```go
+// AuthClient adds authentication tokens to client requests
+func AuthClient(opts ClientOptions) client.Wrapper
+func FromToken(token string) client.Wrapper
+func FromContext(authProvider auth.Auth) client.Wrapper
+```
+
+Features:
+- Automatic token injection
+- Static token support
+- Dynamic token generation from context
+- Works with Call, Stream, and Publish
+
+### 3. **Metadata Helpers** ✅
+
+**Status:** IMPLEMENTED in `wrapper/auth/metadata.go`
+
+```go
+// Standard token extraction and injection
+func TokenFromMetadata(md metadata.Metadata) (string, error)
+func TokenToMetadata(md metadata.Metadata, token string) metadata.Metadata
+func AccountFromMetadata(md metadata.Metadata, a auth.Auth) (*auth.Account, error)
+```
+
+Features:
+- Bearer token extraction
+- Case-insensitive header lookup
+- Token format validation
+- Direct account extraction
+
+### 6. **Standalone JWT Implementation** ⚠️
+
+**Status:** Partially complete (low priority)
+
+Current JWT auth in `auth/jwt/jwt.go` depends on external plugin:
+```go
+jwtToken "github.com/micro/plugins/v5/auth/jwt/token"
+```
+
+**Note:** This is NOT a blocker. The wrappers work with any auth.Auth implementation including:
+- JWT auth (with plugin dependency)
+- Noop auth (for development)
+- Custom auth implementations
+
+**Future improvement:** Create self-contained JWT implementation to remove plugin dependency.
+
+### 4. **Examples** ✅
+
+**Status:** IMPLEMENTED in `examples/auth/`
+
+Complete working example with:
+- Protected Greeter service (server/)
+- Client with authentication (client/)
+- Proto definitions (proto/)
+- Comprehensive README with:
+  - Architecture diagrams
+  - Code walkthrough
+  - Auth strategies
+  - Authorization rules
+  - Testing guide
+  - Production considerations
+  - Troubleshooting guide
+
+### 5. **Documentation** ✅
+
+**Status:** IMPLEMENTED
+
+Complete documentation:
+- `wrapper/auth/README.md` - Full API reference (200+ lines)
+- `examples/auth/README.md` - Integration tutorial (400+ lines)
+- Server wrapper documentation with examples
+- Client wrapper documentation with examples
+- Metadata helpers API reference
+- Best practices guide
+- Troubleshooting guide
+- Production considerations
+
+---
+
+## 🔍 Detailed Analysis
+
+### JWT Implementation Dependency Issue
+
+File: `auth/jwt/jwt.go:7`
+```go
+jwtToken "github.com/micro/plugins/v5/auth/jwt/token"
+```
+
+This depends on:
+- `github.com/micro/plugins` repository
+- Must be separately installed
+- May not be maintained
+- Breaks self-contained promise
+
+**Recommendation:** Create standalone JWT implementation in `auth/jwt/token/`
+
+### Rules Verification Works Well
+
+The `Verify()` function in `rules.go` is well-implemented:
+- ✅ Handles wildcards correctly
+- ✅ Priority-based evaluation
+- ✅ Supports resource hierarchies (e.g., `/foo/*` matches `/foo/bar`)
+- ✅ Public vs authenticated vs scoped access
+- ✅ Tested (see `rules_test.go`)
+
+### Context Integration Exists
+
+```go
+// From auth.go
+func AccountFromContext(ctx context.Context) (*Account, bool)
+func ContextWithAccount(ctx context.Context, account *Account) context.Context
+```
+
+This is ready to use once wrappers are implemented.
+
+---
