+# 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

+# 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
+```
+
+## Project Structure

+
+## 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
+

 ## 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`

+
+```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.

+## 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` |

+| **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"),
+)
+```
+

+# 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 (

+    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),
+)
+
+// 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)
+
+## 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.

+
+## MCP & AI Agents
+
+This service is MCP-enabled by default. When running, AI agents can discover
+and call your service endpoints automatically.
+
+**MCP tools endpoint:** http://localhost:3001/mcp/tools
+
+### Test with curl
+
+` + "```bash" + `
+# List available tools
+curl http://localhost:3001/mcp/tools | jq
+
+# Call the service via MCP
+curl -X POST http://localhost:3001/mcp/call \
+  -H 'Content-Type: application/json' \
+  -d '{"tool": "{{lower .Alias}}.{{title .Alias}}.Call", "arguments": {"name": "Alice"}}'
+` + "```" + `
+
+### Use with Claude Code
+
+` + "```bash" + `
+# Start MCP server for Claude Code
+micro mcp serve
+` + "```" + `
+
+Or add to your Claude Code config:
+
+` + "```json" + `
+{
+  "mcpServers": {
+    "{{lower .Alias}}": {
+      "command": "micro",
+      "args": ["mcp", "serve"]
+    }
+  }
+}
+` + "```" + `
+
+### Writing Good Tool Descriptions
+
+AI agents work best when your handler methods have clear doc comments:
+
+` + "```go" + `
+// CreateUser registers a new user account with the given email and name.
+// Returns the created user with their assigned ID.
+//
+// @example {"email": "alice@example.com", "name": "Alice Smith"}
+func (s *Users) CreateUser(ctx context.Context, req *CreateRequest, rsp *CreateResponse) error {
+    // ...
+}

+
+## Prerequisites
+
+You need at least one microservice running with the go-micro framework. The service will automatically be discovered via the registry (mdns by default).
+
+Example service:
+```bash
+cd examples/mcp/hello
+go run main.go
+```
+
+## List Available Tools
+
+### Human-readable list
+```bash
+micro mcp list
+```
+
+Output:
+```
+Available MCP Tools:
+
+Service: greeter
+  • greeter.Greeter.SayHello
+
+Total: 1 tools
+```
+
+### JSON output
+```bash
+micro mcp list --json
+```
+
+Output:
+```json
+{
+  "count": 1,
+  "tools": [
+    {
+      "description": "Call SayHello on greeter service",
+      "endpoint": "Greeter.SayHello",
+      "name": "greeter.Greeter.SayHello",
+      "service": "greeter"
+    }
+  ]
+}
+```
+
+## Test a Tool
+
+### Basic test
+```bash
+micro mcp test greeter.Greeter.SayHello '{"name": "Alice"}'
+```
+
+Output:
+```
+Testing tool: greeter.Greeter.SayHello
+Service: greeter
+Endpoint: Greeter.SayHello
+Input: {"name": "Alice"}
+
+✅ Call successful!
+
+Response:
+{
+  "message": "Hello Alice!"
+}
+```
+
+### Test with default empty input
+```bash
+micro mcp test greeter.Greeter.SayHello
+```
+
+This will call the tool with an empty JSON object `{}`.
+
+## Generate Documentation
+
+### Markdown documentation (stdout)
+```bash
+micro mcp docs
+```
+
+Output:

+# agent.run('Your query here')
+```
+
+Save to file:
+```bash
+micro mcp export langchain --output langchain_tools.py
+```
+
+### Export to OpenAPI 3.0
+
+Generate an OpenAPI specification:
+
+```bash
+micro mcp export openapi
+```
+
+Output:
+```json
+{
+  "components": {
+    "securitySchemes": {

+  "servers": [
+    {
+      "description": "MCP Gateway",
+      "url": "http://localhost:3000"
+    }
+  ]
+}
+```
+
+Save to file:
+```bash
+micro mcp export openapi --output openapi.json
+```
+
+### Export to raw JSON
+
+Export raw tool definitions:
+
+```bash
+micro mcp export json
+```
+
+This is similar to `micro mcp docs --format json` but specifically for export purposes.
+
+Save to file:
+```bash
+micro mcp export json --output tools.json
+```
+
+## Using with Different Registries
+
+By default, the commands use mdns registry. You can specify a different registry:
+
+```bash
+# Using consul
+micro mcp list --registry consul --registry_address consul:8500
+
+# Using etcd
+micro mcp list --registry etcd --registry_address etcd:2379
+```
+
+## Integration Examples
+
+### Using LangChain Export with Claude
+
+1. Export your tools to LangChain format:
+```bash
+micro mcp export langchain --output my_tools.py
+```
+
+2. Use in your Python agent:
+```python
+from my_tools import tools
+from langchain.agents import initialize_agent, AgentType
+from langchain.chat_models import ChatAnthropic
+
+llm = ChatAnthropic(model="claude-3-sonnet-20240229")
+agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION)
+
+result = agent.run("Greet Alice")
+print(result)
+```
+
+### Using OpenAPI Export with GPT
+
+1. Export to OpenAPI:
+```bash
+micro mcp export openapi --output openapi.json
+```
+
+2. Upload to ChatGPT as a custom GPT action or use with OpenAI Assistants API.
+
+### Documentation for AI Agents
+
+Generate documentation that AI agents can read to understand your services:
+
+```bash
+micro mcp docs --format json --output service-catalog.json
+```
+
+This JSON file can be fed to AI agents for service discovery and understanding.
+
+## Advanced Usage
+
+### Piping and Processing
+
+You can pipe the output to other tools:
+
+```bash
+# Count tools per service
+micro mcp list --json | jq '.tools | group_by(.service) | map({service: .[0].service, count: length})'
+
+# Extract all tool names
+micro mcp list --json | jq -r '.tools[].name'
+
+# Filter tools by service
+micro mcp list --json | jq '.tools[] | select(.service == "greeter")'
+```
+
+### Monitoring and CI/CD
+
+Use these commands in your CI/CD pipeline:
+
+```bash
+# Validate all services are discoverable
+SERVICE_COUNT=$(micro mcp list --json | jq '.count')
+if [ "$SERVICE_COUNT" -lt 5 ]; then
+  echo "Error: Expected at least 5 services, found $SERVICE_COUNT"
+  exit 1
+fi
+
+# Generate documentation on each deployment
+micro mcp docs --output docs/mcp-services.md
+git add docs/mcp-services.md
+git commit -m "Update MCP service documentation"
+```
+
+### Testing in Development
+
+Create a script to test all your tools:
+
+```bash
+#!/bin/bash
+# test-all-tools.sh
+
+TOOLS=$(micro mcp list --json | jq -r '.tools[].name')
+
+for tool in $TOOLS; do
+  echo "Testing $tool..."
+  micro mcp test "$tool" "{}" || echo "Failed: $tool"
+done
+```
+
+## Troubleshooting
+
+### No tools found
+
+If `micro mcp list` shows 0 tools:
+
+1. Verify services are running:
+```bash
+ps aux | grep "your-service"
+```
+
+2. Check registry (mdns might need time to discover):
+```bash
+# Wait a few seconds and try again
+sleep 3
+micro mcp list
+```
+
+3. Use a different registry if mdns is unreliable:
+```bash
+# Start services with consul
+micro --registry consul server
+
+# List with consul
+micro mcp list --registry consul
+```
+
+### Service not responding in tests
+
+If `micro mcp test` fails:
+
+1. Verify the tool name is correct:
+```bash
+micro mcp list
+```
+
+2. Check the JSON input format:
+```bash
+# Invalid
+micro mcp test service.Handler.Method '{invalid}'
+
+# Valid
+micro mcp test service.Handler.Method '{"key": "value"}'
+```
+
+3. Check service logs for errors.

+# LlamaIndex Go Micro Integration
+
+[![PyPI version](https://badge.fury.io/py/go-micro-llamaindex.svg)](https://badge.fury.io/py/go-micro-llamaindex)
+[![License](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)
+
+Official LlamaIndex integration for Go Micro services. This package enables LlamaIndex agents to discover and call Go Micro microservices through the Model Context Protocol (MCP).
+
+## Features
+
+- **Automatic Service Discovery** - Discovers available services from MCP gateway
+- **Dynamic Tool Generation** - Converts service endpoints into LlamaIndex tools
+- **Rich Descriptions** - Uses service metadata for accurate tool descriptions
+- **Authentication Support** - Bearer token auth with scope-based permissions
+- **RAG Integration** - Combine service tools with LlamaIndex's RAG capabilities
+- **Type-Safe** - Fully typed with Python 3.8+ type hints
+
+## Installation
+
+```bash
+pip install go-micro-llamaindex
+```
+
+## Quick Start
+
+### 1. Start Your Go Micro Services
+
+```bash
+# Start MCP gateway
+micro mcp serve --address :3000
+```
+
+### 2. Create LlamaIndex Agent
+
+```python
+from go_micro_llamaindex import GoMicroToolkit
+from llama_index.core.agent import ReActAgent
+from llama_index.llms.openai import OpenAI
+
+# Initialize toolkit from MCP gateway
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Create agent
+llm = OpenAI(model="gpt-4")
+agent = ReActAgent.from_tools(toolkit.get_tools(), llm=llm, verbose=True)
+
+# Use the agent!
+response = agent.chat("Create a user named Alice with email alice@example.com")
+print(response)
+```
+
+## Usage Examples
+
+### Basic Tool Discovery
+
+```python
+from go_micro_llamaindex import GoMicroToolkit
+
+# Connect to MCP gateway
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# List available tools
+for tool in toolkit.get_tools():
+    print(f"Tool: {tool.metadata.name}")
+    print(f"Description: {tool.metadata.description}")
+    print()
+```
+
+### Authentication
+
+```python
+from go_micro_llamaindex import GoMicroToolkit
+
+# Create toolkit with authentication
+toolkit = GoMicroToolkit.from_gateway(
+    gateway_url="http://localhost:3000",
+    auth_token="your-bearer-token"
+)
+
+# Tools will automatically use the auth token
+tools = toolkit.get_tools()
+```
+
+### Filter Tools by Service
+
+```python
+from go_micro_llamaindex import GoMicroToolkit
+
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Get only user service tools
+user_tools = toolkit.get_tools(service_filter="users")
+
+# Get tools matching a pattern
+blog_tools = toolkit.get_tools(name_pattern="blog.*")
+```
+
+### Custom Tool Selection
+
+```python
+from go_micro_llamaindex import GoMicroToolkit
+
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Select specific tools
+selected_tools = toolkit.get_tools(
+    include=["users.Users.Get", "users.Users.Create"]
+)
+
+# Exclude certain tools
+filtered_tools = toolkit.get_tools(
+    exclude=["users.Users.Delete"]
+)
+```
+
+### RAG + Microservices
+
+```python
+from go_micro_llamaindex import GoMicroToolkit
+from llama_index.core import VectorStoreIndex, Document
+from llama_index.core.agent import ReActAgent
+from llama_index.core.tools import QueryEngineTool, ToolMetadata
+from llama_index.llms.openai import OpenAI
+
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Combine service tools with a RAG query engine
+index = VectorStoreIndex.from_documents([...])
+rag_tool = QueryEngineTool(
+    query_engine=index.as_query_engine(),
+    metadata=ToolMetadata(name="docs", description="Search documentation"),
+)
+
+all_tools = [rag_tool] + toolkit.get_tools()
+agent = ReActAgent.from_tools(all_tools, llm=OpenAI(model="gpt-4"))
+```
+
+### Multi-Agent Workflows
+
+```python
+from go_micro_llamaindex import GoMicroToolkit
+from llama_index.core.agent import ReActAgent
+from llama_index.llms.openai import OpenAI
+
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+llm = OpenAI(model="gpt-4")
+
+# Agent 1: User management
+user_agent = ReActAgent.from_tools(
+    toolkit.get_tools(service_filter="users"), llm=llm
+)
+
+# Agent 2: Blog management
+blog_agent = ReActAgent.from_tools(
+    toolkit.get_tools(service_filter="blog"), llm=llm
+)
+
+# Coordinate between agents
+user_result = user_agent.chat("Create user Alice")
+blog_result = blog_agent.chat(f"Create blog post for {user_result}")
+```
+
+### Error Handling
+
+```python
+from go_micro_llamaindex import GoMicroToolkit, GoMicroError
+
+try:
+    toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+    tools = toolkit.get_tools()
+except GoMicroError as e:
+    print(f"Error: {e}")
+```
+
+### Advanced Configuration
+
+```python
+from go_micro_llamaindex import GoMicroToolkit, GoMicroConfig
+
+config = GoMicroConfig(
+    gateway_url="http://localhost:3000",
+    auth_token="your-token",
+    timeout=30,
+    retry_count=3,
+    retry_delay=1.0,
+    verify_ssl=True,
+)
+
+toolkit = GoMicroToolkit(config)
+tools = toolkit.get_tools()
+```

+
+## Troubleshooting
+
+### Gateway Connection Issues
+
+If you can't connect to the MCP gateway:
+
+1. Verify the gateway is running:
+```bash
+curl http://localhost:3000/health
+```
+
+2. Check the gateway URL is correct
+3. Verify firewall settings
+
+### Authentication Errors
+
+If you get authentication errors:
+
+1. Verify your token is valid
+2. Check the token has required scopes
+3. Review gateway logs for details
+
+### Tool Discovery Issues
+
+If tools aren't being discovered:
+
+1. List services from gateway:
+```bash
+curl http://localhost:3000/mcp/tools
+```
+
+2. Verify services are registered
+3. Check service metadata is correct

+# LangChain Go Micro Integration
+
+[![PyPI version](https://badge.fury.io/py/langchain-go-micro.svg)](https://badge.fury.io/py/langchain-go-micro)
+[![License](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)
+
+Official LangChain integration for Go Micro services. This package enables LangChain agents to discover and call Go Micro microservices through the Model Context Protocol (MCP).
+
+## Features
+
+- 🔍 **Automatic Service Discovery** - Discovers available services from MCP gateway
+- 🛠️ **Dynamic Tool Generation** - Converts service endpoints into LangChain tools
+- 📝 **Rich Descriptions** - Uses service metadata for accurate tool descriptions
+- 🔐 **Authentication Support** - Bearer token auth with scope-based permissions
+- ⚡ **Type-Safe** - Fully typed with Python 3.8+ type hints
+- 🎯 **Easy Integration** - Works with any LangChain agent
+
+## Installation
+
+```bash
+pip install langchain-go-micro
+```
+
+## Quick Start
+
+### 1. Start Your Go Micro Services
+
+```bash
+# Start MCP gateway
+micro mcp serve --address :3000
+```
+
+### 2. Create LangChain Agent
+
+```python
+from langchain_go_micro import GoMicroToolkit
+from langchain.agents import initialize_agent, AgentType
+from langchain_openai import ChatOpenAI
+
+# Initialize toolkit from MCP gateway
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Create agent
+llm = ChatOpenAI(model="gpt-4")
+agent = initialize_agent(
+    toolkit.get_tools(),
+    llm,
+    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
+    verbose=True
+)
+
+# Use the agent!
+result = agent.run("Create a user named Alice with email alice@example.com")
+print(result)
+```
+
+## Usage Examples
+
+### Basic Tool Discovery
+
+```python
+from langchain_go_micro import GoMicroToolkit
+
+# Connect to MCP gateway
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# List available tools
+for tool in toolkit.get_tools():
+    print(f"Tool: {tool.name}")
+    print(f"Description: {tool.description}")
+    print()
+```
+
+### Authentication
+
+```python
+from langchain_go_micro import GoMicroToolkit
+
+# Create toolkit with authentication
+toolkit = GoMicroToolkit.from_gateway(
+    gateway_url="http://localhost:3000",
+    auth_token="your-bearer-token"
+)
+
+# Tools will automatically use the auth token
+tools = toolkit.get_tools()
+```
+
+### Filter Tools by Service
+
+```python
+from langchain_go_micro import GoMicroToolkit
+
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Get only user service tools
+user_tools = toolkit.get_tools(service_filter="users")
+
+# Get tools matching a pattern
+blog_tools = toolkit.get_tools(name_pattern="blog.*")
+```
+
+### Custom Tool Selection
+
+```python
+from langchain_go_micro import GoMicroToolkit
+
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Select specific tools
+selected_tools = toolkit.get_tools(
+    include=["users.Users.Get", "users.Users.Create"]
+)
+
+# Exclude certain tools
+filtered_tools = toolkit.get_tools(
+    exclude=["users.Users.Delete"]
+)
+```
+
+### Multi-Agent Workflows
+
+```python
+from langchain_go_micro import GoMicroToolkit
+from langchain.agents import initialize_agent, AgentType
+from langchain_openai import ChatOpenAI
+
+# Create specialized agents for different services
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Agent 1: User management
+user_agent = initialize_agent(
+    toolkit.get_tools(service_filter="users"),
+    ChatOpenAI(model="gpt-4"),
+    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION
+)
+
+# Agent 2: Order processing
+order_agent = initialize_agent(
+    toolkit.get_tools(service_filter="orders"),
+    ChatOpenAI(model="gpt-4"),
+    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION
+)
+
+# Coordinate between agents
+user = user_agent.run("Create user Alice")
+order = order_agent.run(f"Create order for user {user['id']}")
+```
+
+### Error Handling
+
+```python
+from langchain_go_micro import GoMicroToolkit, GoMicroError
+
+try:
+    toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+    tools = toolkit.get_tools()
+except GoMicroError as e:
+    print(f"Error: {e}")
+    # Handle error (gateway unreachable, auth failed, etc.)
+```
+
+### Advanced Configuration
+
+```python
+from langchain_go_micro import GoMicroToolkit, GoMicroConfig
+
+config = GoMicroConfig(
+    gateway_url="http://localhost:3000",
+    auth_token="your-token",
+    timeout=30,  # Request timeout in seconds
+    retry_count=3,  # Number of retries on failure
+    retry_delay=1.0,  # Delay between retries
+    verify_ssl=True,  # SSL certificate verification
+)
+
+toolkit = GoMicroToolkit(config)
+tools = toolkit.get_tools()
+```

+
+### With LangChain Agents
+
+```python
+from langchain_go_micro import GoMicroToolkit
+from langchain.agents import initialize_agent, AgentType
+from langchain_openai import ChatOpenAI
+
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+llm = ChatOpenAI(model="gpt-4")
+
+agent = initialize_agent(
+    toolkit.get_tools(),
+    llm,
+    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
+    verbose=True
+)
+```
+
+### With LangChain Memory
+
+```python
+from langchain_go_micro import GoMicroToolkit
+from langchain.agents import initialize_agent, AgentType

+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+memory = ConversationBufferMemory(memory_key="chat_history")
+
+agent = initialize_agent(
+    toolkit.get_tools(),
+    ChatOpenAI(model="gpt-4"),
+    agent=AgentType.CONVERSATIONAL_REACT_DESCRIPTION,
+    memory=memory,
+    verbose=True
+)
+```
+
+### With Custom LLMs
+
+```python
+from langchain_go_micro import GoMicroToolkit
+from langchain.agents import initialize_agent, AgentType
+from langchain_anthropic import ChatAnthropic
+
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Use Claude instead of GPT
+agent = initialize_agent(
+    toolkit.get_tools(),
+    ChatAnthropic(model="claude-3-sonnet-20240229"),
+    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
+    verbose=True
+)
+```

+
+## Troubleshooting
+
+### Gateway Connection Issues
+
+If you can't connect to the MCP gateway:
+
+1. Verify the gateway is running:
+```bash
+curl http://localhost:3000/health
+```
+
+2. Check the gateway URL is correct
+3. Verify firewall settings
+
+### Authentication Errors
+
+If you get authentication errors:
+
+1. Verify your token is valid
+2. Check the token has required scopes
+3. Review gateway logs for details
+
+### Tool Discovery Issues
+
+If tools aren't being discovered:
+
+1. List services from gateway:
+```bash
+curl http://localhost:3000/mcp/tools
+```
+
+2. Verify services are registered
+3. Check service metadata is correct

-## Coming Soon
+### [multi-service](./multi-service/)
+Multiple services in a single binary — the modular monolith pattern:
+- Isolated server, client, store, and cache per service
+- Shared registry and broker for inter-service communication
+- Coordinated lifecycle with `service.Group`
+- Start monolith, split later when you need to scale independently
 
-The following examples are planned:
+**Run it:**
+```bash
+cd multi-service
+go run .
+```
+
+### [deployment](./deployment/)
+Docker Compose deployment with MCP gateway, Consul registry, and Jaeger tracing:
+- Production-like architecture in one `docker-compose up`
+- Standalone MCP gateway connected to service registry
+- Distributed tracing with OpenTelemetry + Jaeger
+
+### MCP Examples
+
+See the [mcp/](./mcp/) directory for AI agent integration examples:
+- **[hello](./mcp/hello/)** - Minimal MCP service (start here)
+- **[crud](./mcp/crud/)** - CRUD contact book with full agent documentation
+- **[workflow](./mcp/workflow/)** - Cross-service orchestration via AI agents
+- **[documented](./mcp/documented/)** - All MCP features with auth scopes
+
+### [agent-demo](./agent-demo/)
+Multi-service project management app (Projects, Tasks, Team) with seed data and agent playground integration.
+
+## Coming Soon
 
 - **pubsub-events** - Event-driven architecture with NATS
 - **grpc-integration** - Using go-micro with gRPC
-- **production-ready** - Complete production-grade service with observability

+# Agent Demo
+
+A multi-service project management app that demonstrates AI agents interacting with Go Micro services through MCP.
+
+## What's Included
+
+Three services registered in a single process:
+
+| Service | Endpoints | Description |
+|---------|-----------|-------------|
+| **ProjectService** | Create, Get, List | Manage projects with status tracking |
+| **TaskService** | Create, List, Update | Tasks with assignees, priorities, and status |
+| **TeamService** | Add, List, Get | Team members with roles and skills |
+
+The demo starts with seed data: 2 projects, 7 tasks, and 4 team members.
+
+## Run
+
+```bash
+go run main.go
+```
+
+Endpoints:
+- **MCP Gateway:** http://localhost:3000
+- **MCP Tools:** http://localhost:3000/mcp/tools
+- **WebSocket:** ws://localhost:3000/mcp/ws
+
+## Use with Claude Code
+
+```json
+{
+  "mcpServers": {
+    "demo": {
+      "command": "go",
+      "args": ["run", "main.go"],
+      "cwd": "examples/agent-demo"
+    }
+  }
+}
+```
+
+## Example Prompts
+
+Try these with Claude Code or any MCP client:
+
+- "What projects do we have?"
+- "Show me all tasks assigned to alice"
+- "Create a high-priority task for bob to review the design mockups"
+- "Who on the team knows Go?"
+- "Give me a status update on the Website Redesign project"
+- "What tasks are still todo on the API v2 migration?"
+- "Assign the unassigned tasks to charlie"
+- "Mark task-1 as done"
+
+## What This Demonstrates
+
+1. **Zero-config MCP** — Services become AI tools automatically from doc comments
+2. **Cross-service orchestration** — An agent queries projects, tasks, and team in one conversation
+3. **Rich tool descriptions** — `description` struct tags and `@example` comments guide the agent
+4. **Auth scopes** — Read and write operations have separate scopes
+5. **`WithMCP` one-liner** — MCP gateway starts with a single option
+
+See the [blog post](/blog/4) for a detailed walkthrough.
