V3 MCP Optimization

Reduce MCP startup time by pre-warming the connection pool and pre-building the tool index before accepting requests. This approach targets under 400ms initialization, a 4.5x improvement over the ~1.8s cold start baseline.

Implement connection pooling by maintaining a map of reusable connections with idle timeouts, usage limits, and periodic health checks. Evict least-recently-used connections when the pool reaches capacity and pre-warm a minimum number of connections at startup.

The fastest tool lookup uses a hash-based Map index for O(1) exact matches, combined with an LRU cache for frequently used tools. Fuzzy matching handles typos and name variations, targeting under 5ms average lookup time.

Yes, the optimized transport batches non-urgent messages within a configurable timeout or batch size limit and applies gzip compression to payloads. Responses, errors, and high-priority messages bypass batching and send immediately.

Low pool hit rates occur when idle timeouts are too short, endpoints vary per request, or connections are retired too aggressively. Monitor the hit rate metric and tune idleTimeoutMs, maxUsageCount, and minConnections to keep it above 90%.

Monitor p95 response time, error rate, connection pool hit rate, tool lookup latency, and memory usage. Treat error rates above 10% or pool hit rates below 50% as critical, and alert when response time exceeds 200ms for five minutes.
