Module tool_discovery_cache 

Tool discovery caching system for MCP to avoid redundant tool searches

This module provides multi-level caching for MCP tool discovery with bloom filters for fast exact-name negative lookups and an LRU cache for positive results. The bloom filter only screens exact tool names; fuzzy discovery keywords are never screened against it because its definitive “no” does not extend to fuzzy matching.
