- Swap the mark3labs MCP dependency for modelcontextprotocol/go-sdk v1.7.0 - Add a declarative tool definition and JSON Schema builder to the tool package - Adapt registered tools to the official low-level handler, recovering panics and mapping failures to JSON-RPC errors - Narrow tool handlers to take a plain argument map instead of an SDK request type - Rewire stdio and HTTP transports onto the official server, moving Authorization parsing into receiving middleware - Add a golden contract test that locks the exposed tool schemas, plus SDK integration and helper tests - Add a test target and run it in the pull request workflow BREAKING CHANGE: The exported helpers change signature. Tool.RegisterRead and Tool.RegisterWrite now take tool.ServerTool instead of server.ServerTool, and the annotation constructors return *mcp.ToolAnnotations from the official SDK. Callers must build tool definitions with tool.NewDefinition and handlers with the func(context.Context, map[string]any) signature. The 30-second SSE heartbeat is removed because the official SDK has no equivalent. ServerOptions.KeepAlive is deliberately not used as a substitute, since it sends MCP ping requests and ping is removed in protocol 2026. HTTP stays stateless=false, so new clients negotiate at most 2025-11-25. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
