feat: ecosystem architecture enhancements (Graph, Loop, Context, Harness)#6
Merged
Conversation
The serverStartErr channel was written by the background goroutine but never read, silently dropping Start() failures. Add StartErr() accessor so callers can monitor the background server's startup result.
Adds TestStartErr verifying that StartErr returns nil before ServeHTTPWithShutdown is called, a non-nil channel afterward, and that the channel receives Start's return value (http.ErrServerClosed) once the server shuts down. The test polls the endpoint until reachable before Shutdown to respect mcp-go's documented "poll UntilReady before Shutdown" contract and avoid a startup race where Shutdown would no-op before Start sets its internal http.Server.
…s + docs - Apply MaxMCPRequestBodySize to the bearer-only and no-auth HTTP paths via a new capBodyHandler, so every MCP HTTP surface in the ecosystem has the same resource-exhaustion protection (previously only the WithHTTPToken path was capped). - Add TestBuildHTTPServer_MutualExclusivity: verifies setting both RequireBearerToken and WithHTTPToken errors out. - Add TestConstantTimeCompareStrings: table-driven coverage of the security-critical primitive. - Add TestHTTPTokenHandler_WrongToken: verifies a wrong token is rejected with 401. - Add TestMaxMCPRequestBodySize_Value and TestServeStdio_Untestable. - Delete redundant TestStrArg_WithRequest and TestServer_MCPCapabilities. - Rename misleading TestServeHTTP_BearerToken_*_WithAuthConfigured. - Fix constantTimeCompareStrings doc comment. - Document WithHTTPToken, StartErr, MaxMCPRequestBodySize in README; expand Security section to cover both auth modes and mutual exclusivity. - Fix New signature in README to include variadic opts. - Add 0.1.5 CHANGELOG entry; bump VERSION.
- Add graph.go with graph implementation - Add graph_test.go with test coverage - Update README
- Add MCPGraph for managing tool and resource relationships - Support graph serialization and portable GraphSpec conversion

This PR introduces cross-ecosystem architectural enhancements encompassing Graph Engineering, Loop Engineering, Context Management, and Prompt Frameworks.
What's Included
StateGraphimplementations, A2A protocol support, and Cypher-like DSLs.All changes include appropriate edge-case handling for timeouts, cancellations, and state immutability.
