Implement Q2 2026 roadmap items for AI-native microservices:
MCP stdio transport:
- JSON-RPC 2.0 over stdio for Claude Code integration
- Methods: initialize, tools/list, tools/call
- Auto-detection: stdio (no address) vs HTTP/SSE (with address)
micro mcp command:
- 'micro mcp serve' - start MCP server (stdio or HTTP)
- 'micro mcp list' - list available tools
- 'micro mcp test' - test a tool (placeholder)
- Enables Claude Code users to add microservices as tools
Gateway refactor:
- Created gateway/api package (reusable, 150 lines)
- Moved gateway logic from cmd/micro/server/gateway.go
- HandlerRegistrar pattern for flexibility
- cmd/micro/server/gateway.go now compatibility wrapper (72 lines)
- 50% code reduction, better separation of concerns
- Library users can now use gateway in custom apps

Major Features:
- Unified gateway architecture (micro run + micro server use same code)
- MCP (Model Context Protocol) integration as library package
- AI-accessible microservices with 3 lines of code
Gateway Unification:
- Created reusable gateway module (cmd/micro/server/gateway.go)
- Updated micro run to use unified gateway (removed duplicate code)
- Conditional authentication (disabled in dev, required in prod)
- Reduced code duplication, simplified maintenance
MCP Integration:
- New library package: gateway/mcp
- Automatic service discovery → MCP tools
- HTTP/SSE transport support (stdio coming soon)
- Works for both library users and CLI users
- CLI flags: --mcp-address for micro run and micro server
Documentation:
- ADR-010: Unified Gateway Architecture
- CLI & Gateway Guide for users
- MCP Gateway README and examples
- Blog post: Making Your Microservices AI-Native with MCP
Breaking Changes: None (fully backward compatible)
