V3 MCP Optimization

If you're running claude-flow v3 with hundreds of MCP tools and seeing 1.8 second cold starts, this skill walks through a complete optimization pass. It implements connection pooling to reuse MCP connections instead of spinning up new ones every request, replaces linear tool lookups with hash table indexing, and adds load balancing across tool calls. The target is sub-100ms p95 response times and 90%+ pool hit rates. The implementation is thorough, covering everything from pre-warming pools on startup to health checking idle connections. This is infrastructure work, so expect to spend time profiling before and after to validate the wins.

MCP Performance Architecture

Current State Analysis

Current MCP Issues:
├── Cold Start Latency: ~1.8s MCP server init
├── Connection Overhead: New connection per request
├── Tool Registry: Linear search O(n) for 213+ tools
├── Transport Layer: No connection reuse
└── Memory Usage: No cleanup of idle connections
