MCP Performance Optimization

Optimize MCP performance with smaller schemas, cached resources, streaming, batching, and better observability.

Quick Answer / TL;DR

Optimize MCP by shrinking tool schemas, limiting output size, caching read-only resources, reusing connections, and tracing downstream API latency separately.

Key Takeaways

  • Keep payloads small.
  • Cache stable resources.
  • Trace every tool call.

Practical optimizations

Most slow MCP experiences are caused by oversized outputs, cold starts, or slow downstream systems rather than JSON-RPC overhead.
