Add agent platform showcase and refactor project structure (#2884)
* feat: add agent platform showcase and blog post Add a complete platform example (Users, Posts, Comments, Mail) that mirrors micro/blog, demonstrating how existing microservices become AI-accessible through MCP with zero code changes. Includes blog post "Your Microservices Are Already an AI Platform" walking through real agent workflows: signup, content creation, commenting, tagging, and cross-service messaging. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * refactor: rename handler types to drop redundant Service suffix UserService → Users, PostService → Posts, CommentService → Comments, MailService → Mail. Matches micro/blog naming convention. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * refactor: consolidate top-level directories, reduce framework bloat Move internal/non-public packages behind internal/ or into their parent packages where they belong: - deploy/ → gateway/mcp/deploy/ (Helm charts belong with the gateway) - profile/ → service/profile/ (preset plugin profiles are a service concern) - scripts/ → internal/scripts/ (install script is not public API) - test/ → internal/test/ (test harness is not public API) - util/ → internal/util/ (internal helpers shouldn't be imported externally) Also fixes CLAUDE.md merge conflict markers and updates project structure documentation. All import paths updated. Build and tests pass. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * refactor: redesign model package to match framework conventions Rename model.Database interface to model.Model (consistent with client.Client, server.Server, store.Store). Remove generics in favor of interface{}-based API with reflection. Key changes: - model.Model interface: Register once, CRUD infers table from type - DefaultModel + NewModel() + package-level convenience functions - Schema registered via Register(&User{}), no per-call schema passing - Memory implementation as default (in model package, like store) - memory/sqlite/postgres backends updated for new interface - protoc-gen-micro generates RegisterXModel() instead of generic factory - All docs, blog, and README updated https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc --------- Co-authored-by: Claude <noreply@anthropic.com> |

Update documentation, add agent demo, and enhance service API (#2882)
* docs: update all four documentation guides and mark Q2 complete - ai-native-services: add WithMCP one-liner, standalone gateway, WebSocket client example, and OpenTelemetry observability section - mcp-security: add OTel distributed tracing, WebSocket authentication (connection-level and per-message), DeniedReason audit field - tool-descriptions: add manual overrides with WithEndpointDocs and export formats section - agent-patterns: add LangChain/LlamaIndex SDK pattern and standalone gateway production pattern with Docker example - Update roadmap: mark Q2 documentation as complete, Q2 at 100% - Update status: reflect all recent completions, shift priorities https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * feat: add agent demo example and blog post Add examples/agent-demo with a multi-service project management app (projects, tasks, team) that demonstrates AI agents interacting with Go Micro services through MCP. Includes seed data and example prompts. Add blog post 4 "Agents Meet Microservices: A Hands-On Demo" walking through the example code and showing cross-service agent workflows. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * feat: enable multiple services in a single binary Remove global state mutations from service and cmd option functions so that configuring one service no longer overwrites another's settings. Key changes: - service/options.go: remove all DefaultXxx global writes from option functions; newOptions() now creates fresh Server, Client, Store, and Cache per service while sharing Registry, Broker, and Transport - cmd/cmd.go: newCmd() uses local copies instead of pointers to package globals; Before() no longer mutates DefaultXxx vars - cmd/options.go: remove global mutations from all option functions - service/service.go: export ServiceImpl type for cross-package use - service/group.go: new Group type for multi-service lifecycle - micro.go: add Start/Stop to Service interface, expose Group and NewGroup convenience function - examples/multi-service: working example with two services https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * docs: highlight multi-service binary support Add multi-service section to README with code example, update features list, add to examples index, and note in status summary. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * feat: unify service API and clean up developer experience - Unified service creation: micro.New("name", opts...) as canonical API - Clean handler registration: service.Handle(handler, opts...) accepts server.HandlerOption args directly, no need to reach through Server() - Unexported serviceImpl: users interact through Service interface only - Service groups use Service interface (not concrete type) - Fixed Stop() to properly propagate BeforeStop/AfterStop errors - Fixed store init: error-level log instead of fatal on init failure - Updated all examples to use consistent patterns - Updated README, getting-started, MCP docs, and guides - Added blog post about the DX cleanup https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * fix: add blog post 5 to blog index Blog post 5 (Developer Experience Cleanup) existed as a file but was missing from the blog index page. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * feat: make micro new generate MCP-enabled services by default - main.go template includes mcp.WithMCP(":3001") by default - Handler template has agent-friendly doc comments with @example tags - Proto template has descriptive field comments - README includes MCP usage, Claude Code config, and tool description tips - Makefile adds mcp-tools, mcp-test, mcp-serve targets - go.mod updated to Go 1.22 - Added --no-mcp flag to opt out of MCP integration - Post-create output shows MCP endpoint URLs https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * docs: add MCP migration guide and troubleshooting guide - Migration guide: 3 approaches to add MCP to existing services (WithMCP one-liner, standalone gateway, CLI) - Troubleshooting guide: common issues with agents, WebSocket, Claude Code, auth, rate limiting, and performance https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * refactor: rename model/ package to ai/ for AI model providers The model/ package name conflicted with the conventional use of "model" for data models. Renamed to ai/ which better describes the package's purpose (AI provider abstraction for Anthropic, OpenAI, etc.) and frees up model/ for future data model layer use. - Rename model/ → ai/ with package name change - Update all Go imports from go-micro.dev/v5/model to go-micro.dev/v5/ai - Update cmd/micro/server/server.go references (model.X → ai.X) - Update all documentation and roadmap references - All tests pass, CLI builds successfully https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * feat: add model package for typed data access with CRUD and queries New model/ package provides a typed data model layer using Go generics. Supports structured CRUD operations, WHERE filters, ordering, pagination, and automatic schema creation from struct tags. Three backends: - memory: in-memory for development and testing - sqlite: embedded SQL for dev and single-node production - postgres: full PostgreSQL for production deployments Key features: - Generic Model[T] with Create/Read/Update/Delete/List/Count - Query builder: Where(), WhereOp(), OrderAsc/Desc(), Limit(), Offset() - Struct tags: model:"key" for primary key, model:"index" for indexes - Auto table creation from struct schema - 19 tests passing across memory and sqlite backends https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * feat: add model code generation to protoc-gen-micro Extend the micro plugin to generate model structs from proto messages annotated with // @model. Generated alongside client/server code in the same .pb.micro.go file. For a proto message like: // @model message User { string id = 1; string name = 2; } Generates: - UserModel struct with model:"key" and json tags - NewUserModel(db) factory returning *model.Model[UserModel] - UserModelFromProto(*User) *UserModel converter - (*UserModel).ToProto() *User converter Supports @model(table=custom_table, key=custom_field) options. Adds GetComments() to generator for plugin comment inspection. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * feat: add Model() to Service interface for Client/Server/Model trifecta Every service now exposes Client(), Server(), and Model() — call services, handle requests, and save/query data from the same interface. Includes README docs, blog post, and a full model guide on the docs site. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * feat: add Helm chart for MCP gateway Kubernetes deployment Adds official Helm chart at deploy/helm/mcp-gateway/ with: - Deployment, Service, ServiceAccount templates - HPA for auto-scaling based on CPU/memory - Ingress with TLS support - Configurable registry (consul, etcd, mdns), rate limiting, JWT auth, audit logging, and per-tool scopes - Security context (non-root, read-only rootfs, drop all caps) - NOTES.txt with post-install connection instructions Updates roadmap and status docs to reflect Helm Charts as delivered. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * docs: add Helm chart entry to changelog https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * feat: add per-tool circuit breakers to MCP gateway Protects downstream services from cascading failures. When a tool's RPC calls fail repeatedly, the circuit opens and rejects requests immediately until the service recovers (half-open probe pattern). - CircuitBreakerConfig with MaxFailures, Timeout, MaxHalfOpen - Per-tool breakers created during service discovery - Integrated into HTTP call path with 503 response when open - Records success/failure after each RPC call - --circuit-breaker and --circuit-breaker-timeout CLI flags - 8 unit tests covering all state transitions https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc --------- Co-authored-by: Claude <noreply@anthropic.com> |

feat: add WebSocket transport for MCP gateway (#2867)
Add bidirectional WebSocket transport at /mcp/ws using JSON-RPC 2.0 protocol (same as stdio). This enables persistent connections for real-time AI agents that need streaming tool interactions. New files: - gateway/mcp/websocket.go: WebSocketTransport with connection-level auth, per-message auth fallback, write serialization, OTel tracing - gateway/mcp/websocket_test.go: 14 tests covering initialize, tools/list, tool calls, auth (header + param), scopes, rate limiting, audit, concurrent requests, multiple connections, error handling, and connection persistence Changes: - gateway/mcp/mcp.go: Register /mcp/ws handler in serveHTTP - go.mod: Added github.com/gorilla/websocket v1.5.3 Auth supports two modes: - Connection-level: Bearer token in WebSocket upgrade request headers - Per-message: _token field in JSON-RPC params (same as stdio) https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc Co-authored-by: Claude <noreply@anthropic.com> |

Claude/update docs roadmap f zd2 j (#2866)
* Update docs and roadmap to March 2026 with focus priorities - ROADMAP.md: Updated from Nov 2025 to reflect Q1 completions and current state - ROADMAP_2026.md: Updated status to March 2026, added model package as delivered - CURRENT_STATUS_SUMMARY.md: Rewrote with March 2026 status and clear next priorities - PROJECT_STATUS_2026.md: Added model package section, updated recommendations - Website roadmap: Updated Q3 security status and timestamps Key focus areas identified: documentation guides, multi-protocol MCP, LlamaIndex SDK, and OpenTelemetry integration. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * Add CLAUDE.md and four documentation guides to fill doc gaps - CLAUDE.md: Project guide with structure, build commands, and priorities - ai-native-services.md: End-to-end tutorial building an MCP-enabled task service - mcp-security.md: Production security guide (auth, scopes, rate limiting, audit) - tool-descriptions.md: Best practices for writing Go comments that help agents - agent-patterns.md: Six integration patterns from single-agent to event-driven - Updated docs index with new "AI & Agents" section linking all four guides These were the highest priority gaps identified in the roadmap analysis: the framework has solid features that were under-documented. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc * feat: add OpenTelemetry tracing to MCP gateway Integrate OpenTelemetry spans into the MCP gateway for both HTTP and stdio transports. Each tool call now creates a server span with rich attributes (tool name, account ID, auth outcome, transport type). Trace context is propagated to downstream RPC calls via metadata, enabling end-to-end distributed tracing through Jaeger, Grafana, etc. New files: - gateway/mcp/otel.go: Span creation, attribute constants, metadata carrier - gateway/mcp/otel_test.go: 8 tests covering span creation, auth denied/allowed, rate limiting, trace propagation, noop provider, and missing token Changes: - Options.TraceProvider: Optional trace.TracerProvider field - handleCallTool (HTTP): Creates OTel spans with auth/rate-limit attributes - handleToolsCall (stdio): Same instrumentation for stdio transport - go.mod: Added go.opentelemetry.io/otel/sdk v1.35.0 (test dependency) The existing MCP trace ID (UUID) is preserved for backward compatibility and recorded as a span attribute alongside the W3C trace context. https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc --------- Co-authored-by: Claude <noreply@anthropic.com> |
