## 📊 What's Been Built

### ✅ Core MCP Integration (Q1 - COMPLETE)
- **MCP Gateway Library** (`gateway/mcp/`) - 2,083 lines
  - HTTP/SSE transport
  - Stdio JSON-RPC 2.0 transport
  - Service discovery & tool generation
  - Schema generation from Go types
  
- **CLI Commands** (`micro mcp`)
  - `micro mcp serve` - Start MCP server (stdio or HTTP)
  - `micro mcp list` - List available tools
  - `micro mcp test` - Test tools with JSON input
  - `micro mcp docs` - Generate documentation
  - `micro mcp export` - Export to various formats (langchain, openapi, json)

- **Documentation**
  - Complete API documentation
  - 2 working examples (hello, documented)
  - Blog post: "Making Microservices AI-Native with MCP"

### ✅ Advanced Features (Q2/Q3 - DELIVERED EARLY)

#### 🔒 Security & Auth
- **Per-Tool Scopes**
  - Service-level: `server.WithEndpointScopes("Blog.Create", "blog:write")`
  - Gateway-level: `Options.Scopes` map for overrides
  - Bearer token authentication
  - Scope enforcement before RPC execution

#### 📊 Observability
- **Tracing**
  - UUID trace IDs per tool call
  - Metadata propagation (`Mcp-Trace-Id`, `Mcp-Tool-Name`, `Mcp-Account-Id`)
  - Full call chain tracking

- **Audit Logging**
  - Immutable audit records per tool call
  - Captures: tool, account, scopes, allowed/denied, duration, errors
  - Callback function: `Options.AuditFunc`

#### 🚦 Rate Limiting
- Per-tool rate limiters
- Configurable requests/second and burst
- Token bucket algorithm

#### 📝 Documentation Extraction
- Auto-extract from Go doc comments
- `@example` tag support for JSON examples
- Struct tag parsing for parameter descriptions
- Manual override via `WithEndpointDocs()`

## 🚀 What Works Today

### For Claude Code Users
```bash
# Start MCP server for Claude Code
micro mcp serve

# Add to ~/.claude/claude_desktop_config.json:
{
  "mcpServers": {
    "my-services": {
      "command": "micro",
      "args": ["mcp", "serve"]
    }
  }
}
```

### For Library Users
```go
package main

import (
    "go-micro.dev/v5"
    "go-micro.dev/v5/gateway/mcp"
)

func main() {
    service := micro.NewService(micro.Name("myservice"))
    service.Init()

    // Add MCP gateway (3 lines!)
    go mcp.ListenAndServe(":3000", mcp.Options{
        Registry: service.Options().Registry,
        Auth:     authProvider,  // Optional: auth.Auth
        Scopes: map[string][]string{  // Optional: per-tool scopes
            "myservice.Handler.Create": {"write"},
        },
        RateLimit: &mcp.RateLimitConfig{  // Optional
            RequestsPerSecond: 10,
            Burst:             20,
        },
        AuditFunc: func(r mcp.AuditRecord) {  // Optional
            log.Printf("[audit] %+v", r)
        },
    })

    service.Run()
}
```

### For Service Developers
```go
// Just add Go comments - docs extracted automatically!

// GetUser retrieves a user by ID. Returns full profile with email and preferences.
//
// @example {"id": "user-123"}
func (s *UserService) GetUser(ctx context.Context, req *GetUserRequest, rsp *GetUserResponse) error {
    // implementation
}

// Register with scopes
handler := service.Server().NewHandler(
    new(UserService),
    server.WithEndpointScopes("UserService.Delete", "users:admin"),
)
```
