react-render-profile-mcp v0.3.1 - 4 new diagnostic tools for React Compiler, hydration, Zustand, and state cascades
Short summary
react-render-profile-mcp v0.3.1 adds four diagnostic tools targeting React Compiler ineffectiveness, hydration mismatches, external store loops, and state cascade propagation. Each provides root-cause classification and specific fixes instead of generic recommendations. Export a React DevTools profile and pass it to any tool via the MCP server.
- •Four new diagnostic tools: analyze_compiler_efficacy, diagnose_hydration_and_suspense, evaluate_external_store_performance, trace_state_cascade_footprint
- •Identifies specific failure modes (unstable refs, selector loops, sync bypasses) rather than just flagging problems
- •Actionable output with ROI-scored recommendations tailored to each root cause
Generated with AI, which can make mistakes.
