+```
+
+### Testing
+
+- Write unit tests for all new code
+- Ensure existing tests pass
+- Add integration tests for plugin implementations
+- Test with multiple Go versions (1.20+)
+
+```bash
+# Run specific package tests
+go test ./registry/...
+
+# Run with verbose output
+go test -v ./...
+
+# Run specific test
+go test -run TestMyFunction ./pkg/...
+
+# Optional: Use richgo for colored output
+go install github.com/kyoh86/richgo@latest
+richgo test -v ./...
+```
+
+### Documentation
+
+- Update relevant markdown files in `internal/website/docs/`
+- Add examples to `internal/website/docs/examples/` for new features
+- Update README.md for major features

+# 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

+```
+
+### 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"),
+)
+```

 - **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.

+## 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
+# Agent Playground:  http://localhost:8080/agent
+# MCP Tools:         http://localhost:8080/api/mcp/tools
+```
+
+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
+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 `/api/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.

+# 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
+
+---
+

+
+**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

+
+---
+
+## 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:
+
+#### LangChain Integration
+- [ ] `go-micro-langchain` package
+- [ ] Auto-generate LangChain tools from registry
+- [ ] Example: Multi-agent workflow with go-micro services
+
+#### LlamaIndex Integration

+
+**Implemented:**
+```bash
+# Start MCP server
+micro mcp serve                    # Stdio (for Claude Code) ✅
+micro mcp serve --address :3000    # HTTP/SSE (for web agents) ✅
+
+# Development
+micro mcp list                     # List available tools ✅
+micro mcp list --json              # JSON output ✅
+```
+
+**Not Yet Implemented:**
+```bash
+micro mcp test users.Users.Get     # Test a tool (placeholder only)
+micro mcp docs                     # Generate MCP documentation
+micro mcp export langchain         # Export to LangChain format
+micro mcp export openapi           # Export as OpenAPI (for fallback)
+```
+
+#### Interactive Agent Playground
+- [ ] Web UI for testing services with AI
+- [ ] Built into `micro run` dashboard
+- [ ] Chat with your services
+- [ ] See agent tool calls in real-time
+- [ ] Share playground URLs for demos
+
+**Example:**

+http://localhost:8080/playground
+
+> You: "Show me user 123's last 5 orders"
+
+Agent: Let me check that...
+→ Calling users.Users.Get with {"id": "123"}
+→ Calling orders.Orders.List with {"user_id": "123", "limit": 5}
+
+Here are the 5 most recent orders for Alice Smith:
+1. Order #45678 - $125.00 - Shipped (Jan 15)
+2. Order #45123 - $89.99 - Delivered (Jan 10)

+
+## 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

+
+## 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
+
+---
+
+## Key Integrations Priority
+
+### Tier 1: Must-Have (Q2 2026)
+1. **Claude Desktop** (stdio MCP) - Anthropic's flagship IDE
+2. **ChatGPT Plugins** - Largest user base
+3. **Kubernetes** - Production deployment
+4. **OpenTelemetry** - Observability standard
+
+### Tier 2: Important (Q3 2026)
+5. **LangChain** - Popular agent framework
+6. **Google Gemini** - Major AI player
+7. **Consul/etcd** - Service discovery for enterprise
+8. **Vault** - Secrets management
+
+### Tier 3: Nice-to-Have (Q4 2026)
+9. **LlamaIndex** - RAG and data
+10. **AutoGPT** - Autonomous agents
+11. **Microsoft Copilot** - Enterprise AI
+12. **AWS Bedrock** - Multi-model platform
+
+---
+
+## Sustainability Principles
+
+### Open Source Sustainability
+1. **Core stays free** - Framework, basic MCP, CLI always open source
+2. **Community-first** - Features users want, not just what we want to build
+3. **Transparent roadmap** - This document is public
+4. **Contributor recognition** - Credit and compensation for contributions
+
+### Business Sustainability
+1. **Clear value ladder** - Free → SaaS → Enterprise (logical upgrade path)
+2. **High margins** - Software business scales without linear costs
+3. **Multiple revenue streams** - Don't depend on one customer segment
+4. **Profitable by default** - Revenue exceeds costs from Year 1
+
+### Technical Sustainability
+1. **Backward compatibility** - No breaking changes in v5.x
+2. **Stable interfaces** - MCP gateway API won't change unexpectedly
+3. **Performance first** - Fast by default, not through hacks
+4. **Documentation** - Every feature is documented

+
+## 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

+# 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.
+
+---
+
+## 🛠️ Implementation Status

+
+3. ✅ **Metadata Helpers** - `wrapper/auth/metadata.go`
+   - TokenFromMetadata - extract Bearer token
+   - TokenToMetadata - inject Bearer token
+   - AccountFromMetadata - extract and verify in one step
+
+### Phase 2: Important ✅ COMPLETE

+### Options
+
+```
+micro run                    # Gateway on :8080, hot reload enabled
+micro run --address :3000    # Gateway on custom port
+micro run --no-gateway       # Services only, no HTTP gateway
+micro run --no-watch         # Disable hot reload
+micro run --env production   # Use production environment
+micro run github.com/micro/blog  # Clone and run from GitHub
+```
+
+### Calling Services
+
+Via curl:
+```bash
+curl -X POST http://localhost:8080/api/helloworld/Helloworld.Call -d '{"name": "World"}'
+```
+
+Or browse to http://localhost:8080 and use the web interface.
+
+List services:
+```
+micro services
+```
+
+## Configuration (micro.mu)
+
+For multi-service projects, create a `micro.mu` file to define services, dependencies, and environments:
+
+```
+service users
+    path ./users
+    port 8081
+
+service posts
+    path ./posts
+    port 8082
+    depends users
+
+service web
+    path ./web
+    port 8089
+    depends users posts
+
+env development
+    STORE_ADDRESS file://./data
+    DEBUG true
+
+env production
+    STORE_ADDRESS postgres://localhost/db
+```
+
+### Configuration Options
+
+| Property | Description |
+|----------|-------------|
+| `path` | Directory containing the service (with main.go) |
+| `port` | Port the service listens on (for health checks) |
+| `depends` | Services that must start first (space-separated) |
+
+### Environment Management
+
+Environment variables are injected based on the `--env` flag:
+
+```
+micro run                    # Uses 'development' env (default)
+micro run --env production   # Uses 'production' env
+MICRO_ENV=staging micro run  # Uses 'staging' env
+```
+
+### JSON Alternative
+
+You can also use `micro.json` if you prefer:
+
+```json
+{
+  "services": {
+    "users": { "path": "./users", "port": 8081 },
+    "posts": { "path": "./posts", "port": 8082, "depends": ["users"] }
+  },
+  "env": {
+    "development": { "STORE_ADDRESS": "file://./data" }
+  }
+}
+```
+
+### Without Configuration
+
+If no `micro.mu` or `micro.json` exists, `micro run` discovers all `main.go` files and runs them (original behavior).
+
+## Describe the service

+}
+```
+
+## Building and Deployment
+
+### Build Binaries
+
+Build Go binaries for deployment:
+
+```bash
+micro build                     # Build for current OS
+micro build --os linux          # Cross-compile for Linux
+micro build --os linux --arch arm64  # For ARM64
+micro build --output ./dist     # Custom output directory
+```
+
+### Deploy to Server
+
+Deploy to any Linux server with systemd:
+
+```bash
+# First time: set up the server
+ssh user@server
+curl -fsSL https://go-micro.dev/install.sh | sh
+sudo micro init --server
+exit
+
+# Deploy from your laptop
+micro deploy user@server
+```
+
+The deploy command:
+1. Builds binaries for linux/amd64
+2. Copies via SSH to `/opt/micro/bin/`
+3. Sets up systemd services (`micro@<service>`)
+4. Restarts and verifies services are running
+
+### Named Deploy Targets
+
+Add deploy targets to `micro.mu`:
+
+```
+deploy prod
+    ssh deploy@prod.example.com
+
+deploy staging
+    ssh deploy@staging.example.com
+```
+
+Then:
+```bash
+micro deploy prod      # Deploy to production
+micro deploy staging   # Deploy to staging
+```
+
+### Managing Deployed Services
+
+```bash
+# Check status
+micro status --remote user@server
+
+# View logs
+micro logs --remote user@server
+micro logs myservice --remote user@server -f
+
+# Stop a service
+micro stop myservice --remote user@server
+```
+
+See [internal/website/docs/deployment.md](../../internal/website/docs/deployment.md) for the full deployment guide.
+
+## Protobuf 
+
+Use protobuf for code generation with [protoc-gen-micro](https://github.com/micro/go-micro/tree/master/cmd/protoc-gen-micro)
+
+## Server
+
+The micro server is a production web dashboard and authenticated API gateway for interacting with services that are already running (e.g., managed by systemd via `micro deploy`). It does **not** build, run, or watch services — for local development, use `micro run` instead.
+
+Run it like so
+
+```
+micro server
+```
+
+Then browse to [localhost:8080](http://localhost:8080) and log in with the default admin account (`admin`/`micro`).
+
+### API Endpoints 
+
+The API provides a fixed HTTP entrypoint for calling services
+
+```
+curl http://localhost:8080/api/helloworld/Helloworld/Call -d '{"name": "John"}'
+```
+See /api for more details and documentation for each service
+
+### Web Dashboard 
+
+The web dashboard provides a modern, secure UI for managing and exploring your Micro services. Major features include:
+
+- **Dynamic Service & Endpoint Forms**: Browse all registered services and endpoints. For each endpoint, a dynamic form is generated for easy testing and exploration.
+- **API Documentation**: The `/api` page lists all available services and endpoints, with request/response schemas and a sidebar for quick navigation. A documentation banner explains authentication requirements.
+- **JWT Authentication**: All login and token management uses a custom JWT utility. Passwords are securely stored with bcrypt. All `/api/x` endpoints and authenticated pages require an `Authorization: Bearer <token>` header (or `micro_token` cookie as fallback).
+- **Token Management**: The `/auth/tokens` page allows you to generate, view (obfuscated), and copy JWT tokens. Tokens are stored and can be revoked. When a user is deleted, all their tokens are revoked immediately.
+- **User Management**: The `/auth/users` page allows you to create, list, and delete users. Passwords are never shown or stored in plaintext.
+- **Token Revocation**: JWT tokens are stored and checked for revocation on every request. Revoked or deleted tokens are immediately invalidated.
+- **Security**: All protected endpoints use consistent authentication logic. Unauthorized or revoked tokens receive a 401 error. All sensitive actions require authentication.
+- **Logs & Status**: View service logs and status (PID, uptime, etc) directly from the dashboard.
+
+To get started, run:
+
+```
+micro server
+```
+
+Then browse to [localhost:8080](http://localhost:8080) and log in with the default admin account (`admin`/`micro`).
+
+> **Note:** See the `/api` page for details on API authentication and how to generate tokens for use with the HTTP API
+
+## Gateway Architecture
+
+The `micro run` and `micro server` commands both use a unified gateway implementation (`cmd/micro/server/gateway.go`), providing consistent HTTP-to-RPC translation, service discovery, and web UI capabilities.
+
+### Key Differences
+
+| Feature | `micro run` | `micro server` |
+|---------|-------------|----------------|
+| **Purpose** | Development | Production |
+| **Authentication** | Enabled (default `admin`/`micro`) | Enabled (default `admin`/`micro`) |
+| **Process Management** | Yes (builds/runs services) | No (assumes services running) |
+| **Hot Reload** | Yes (watches files) | No |
+| **Scopes** | Available (`/auth/scopes`) | Available (`/auth/scopes`) |
+| **Use Case** | Local development | Deployed API gateway |
+
+### Why Unified?
+
+Previously, each command had its own gateway implementation, leading to code duplication. The unified gateway means:
+
+- New features (like MCP integration) benefit both commands
+- Consistent behavior between development and production
+- Single codebase to test and maintain
+- Same HTTP API, web UI, and service discovery logic
+
+### Gateway Features
+
+Both commands provide:
+
+- **HTTP API**: `POST /api/{service}/{endpoint}` with JSON request/response
+- **Service Discovery**: Automatic detection via registry (mdns/consul/etcd)
+- **Health Checks**: `/health`, `/health/live`, `/health/ready` endpoints
+- **Web Dashboard**: Browse services, test endpoints, view documentation
+- **Hot Service Updates**: Gateway automatically picks up new service registrations
+- **JWT Authentication**: Tokens, user management, login at `/auth/login`, `/auth/tokens`, `/auth/users`
+- **Endpoint Scopes**: Restrict which tokens can call which endpoints via `/auth/scopes`
+- **MCP Integration**: AI tools at `/api/mcp/tools`, agent playground at `/agent`
+
+### Authentication & Scopes
+
+Both `micro run` and `micro server` use the same `auth.Account` type from the go-micro framework. The gateway stores accounts under `auth/<id>` in the default store and uses JWT tokens with RSA256 signing.
+
+**Scope enforcement** applies to all call paths:
+
+| Path | Description |
+|------|-------------|
+| `POST /api/{service}/{endpoint}` | HTTP API calls |
+| `POST /api/mcp/call` | MCP tool invocations |
+| Agent playground | Tool calls made by the AI agent |
+
+Scopes are configured via the web UI at `/auth/scopes`. Each endpoint can require one or more scopes. A token must carry at least one matching scope to call a protected endpoint. The `*` scope on a token bypasses all checks. Endpoints with no scopes set are open to any authenticated token.
+
+See the [Scopes](#scopes) section below for details.
+
+### Development Mode (`micro run`)
+
+```bash
+micro run  # Auth enabled, default admin/micro
+```
+
+- Authentication enabled with default credentials (`admin`/`micro`)
+- Web UI requires login
+- Scopes available for testing access control
+- Ideal for development with realistic auth behavior
+
+### Production Mode (`micro server`)
+
+```bash
+micro server  # Auth enabled, JWT tokens required
+```
+
+- JWT authentication on all API calls
+- User/token management via web UI
+- Secure by default
+- Login required: default credentials `admin/micro`
+
+### Programmatic Gateway Usage
+
+You can also start the gateway programmatically in your own Go code:
+
+```go
+import "go-micro.dev/v5/cmd/micro/server"
+
+// Start gateway with auth (recommended)
+gw, err := server.StartGateway(server.GatewayOptions{
+    Address:     ":8080",
+    AuthEnabled: true,
+})
+
+// Start gateway without auth (testing only)
+gw, err := server.StartGateway(server.GatewayOptions{
+    Address:     ":8080",
+    AuthEnabled: false,
+})
+```
+
+See [`internal/website/docs/architecture/adr-010-unified-gateway.md`](../../internal/website/docs/architecture/adr-010-unified-gateway.md) for architecture details.
+
+### Scopes
+
+Scopes provide fine-grained access control over which tokens can call which service endpoints. They are managed through the web UI at `/auth/scopes` and enforced on every call through the gateway.
+
+#### How It Works
+
+1. **Define scopes on endpoints** — Visit `/auth/scopes` and set required scopes for each service endpoint (e.g., set `billing` on `payments.Payments.Charge`)
+2. **Create tokens with scopes** — Visit `/auth/tokens` and create tokens with matching scopes (e.g., a token with `billing` scope)
+3. **Scopes are enforced** — When a token calls an endpoint, the gateway checks that the token has at least one scope matching the endpoint's required scopes
+
+#### Scope Matching Rules
+
+- Scopes are **exact string matches** — `billing` on a token matches `billing` on an endpoint
+- A token with `*` scope bypasses all scope checks (admin wildcard)
+- Endpoints with **no scopes set** are open to any valid token
+- An endpoint can require **multiple scopes** — the token needs to match just one
+- Scope names are free-form strings — use whatever convention fits your project
+
+#### Common Patterns
+
+| Pattern | Endpoint Scopes | Token Scopes | Result |
+|---------|----------------|--------------|--------|
+| Protect a service | Set `greeter` on all greeter endpoints (use Bulk Set with `greeter.*`) | Token with `greeter` | Token can call any greeter endpoint |
+| Restrict an endpoint | Set `billing` on `payments.Payments.Charge` | Token with `billing` | Only that endpoint is restricted |
+| Role-based | Set `admin` on sensitive endpoints | Admin token with `admin`, user token with `user` | Only admin tokens can call sensitive endpoints |
+| Full access | Any | Token with `*` | Bypasses all scope checks |
+
+#### Relationship to Framework Auth
+
+The gateway's scope system uses `auth.Account` from the go-micro framework. Scopes on accounts are the same `[]string` field used by the framework's `auth.Rules` and `wrapper/auth` package. The gateway stores scope requirements in the default store under `endpoint-scopes/<service>.<endpoint>` keys and checks them on every HTTP request.
+
+For service-level (RPC) auth within the go-micro mesh, use the `wrapper/auth` package which provides `auth.Rules` with priority-based access control. See the [auth wrapper documentation](../../wrapper/auth/README.md) for details.

+A Go microservices toolkit
+
+## Overview
+
+Micro is a toolkit for Go microservices development. It provides the foundation for building services in the cloud. 
+The core of Micro is the [Go Micro](https://github.com/micro/go-micro) framework, which developers import and use in their code to 
+write services. Surrounding this we introduce a number of tools to make it easy to serve and consume services. 
+
+## Install the CLI
+
+Install `micro` via `go install`
+
+```
+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.
+
+Or via install script
+
+```
+wget -q  https://raw.githubusercontent.com/micro/micro/master/scripts/install.sh -O - | /bin/bash
+```
+
+For releases see the [latest](https://go-micro.dev/releases/latest) tag
+
+## Create a service
+
+Create your service (all setup is now automatic!):
+
+```
+micro new helloworld
+```
+
+This will:
+- Create a new service in the `helloworld` directory
+- Automatically run `go mod tidy` and `make proto` for you
+- Show the updated project tree including generated files
+- Warn you if `protoc` is not installed, with install instructions
+
+## Run the service
+
+Run the service
+
+```
+micro run
+```
+
+List services to see it's running and registered itself
+
+```
+micro services
+```
+
+## Describe the service
+
+Describe the service to see available endpoints
+
+```
+micro describe helloworld

+
+Use protobuf for code generation with [protoc-gen-micro](https://go-micro.dev/tree/master/cmd/protoc-gen-micro)
+
+## Server
+
+The micro server is an api and web dashboard that provide a fixed entrypoint for seeing and querying services.
+
+Run it like so
+
+```
+micro server
+```
+
+Then browse to [localhost:8080](http://localhost:8080)
+
+### API Endpoints 
+
+The API provides a fixed HTTP entrypoint for calling services
+
+```
+curl http://localhost:8080/api/helloworld/Helloworld/Call -d '{"name": "John"}'
+```
+See /api for more details and documentation for each service
+
+### Web Dashboard 
+
+The web dashboard provides a modern, secure UI for managing and exploring your Micro services. Major features include:
+
+- **Dynamic Service & Endpoint Forms**: Browse all registered services and endpoints. For each endpoint, a dynamic form is generated for easy testing and exploration.
+- **API Documentation**: The `/api` page lists all available services and endpoints, with request/response schemas and a sidebar for quick navigation. A documentation banner explains authentication requirements.
+- **JWT Authentication**: All login and token management uses a custom JWT utility. Passwords are securely stored with bcrypt. All `/api/x` endpoints and authenticated pages require an `Authorization: Bearer <token>` header (or `micro_token` cookie as fallback).
+- **Token Management**: The `/auth/tokens` page allows you to generate, view (obfuscated), and copy JWT tokens. Tokens are stored and can be revoked. When a user is deleted, all their tokens are revoked immediately.
+- **User Management**: The `/auth/users` page allows you to create, list, and delete users. Passwords are never shown or stored in plaintext.
+- **Token Revocation**: JWT tokens are stored and checked for revocation on every request. Revoked or deleted tokens are immediately invalidated.
+- **Security**: All protected endpoints use consistent authentication logic. Unauthorized or revoked tokens receive a 401 error. All sensitive actions require authentication.
+- **Logs & Status**: View service logs and status (PID, uptime, etc) directly from the dashboard.
+
+To get started, run:
+
+```
+micro server
+```
+
+Then browse to [localhost:8080](http://localhost:8080) and log in with the default admin account (`admin`/`micro`).
+
+> **Note:** See the `/api` page for details on API authentication and how to generate tokens for use with the HTTP API
