V3 MCP Optimization

The fragment presents a coherent MCP optimization architecture (connection pooling, index-based tool registry, load balancing, transport enhancements, and metrics collection) without evident malicious behavior or external data leakage within the shown scope. The design aligns with its optimization goals, though heavy reliance on external modules and disk caches introduces supply-chain and configuration risks. Validation should focus on the trustworthiness of dependencies, secure cache paths, and correctness of dynamic behavior (e.g., eviction, batching thresholds) in a deployed environment.
