Overview
MCP-MCP is a Meta-MCP Server that acts as a tool discovery and provisioning service for the Model Context Protocol (MCP). It maintains a comprehensive database of MCP servers drawn from multiple curated sources, including official MCP servers and community lists. When an AI assistant needs a capability not currently available, MCP-MCP can discover and suggest suitable MCP servers from this aggregated catalog. It functions as a 'phone book' for MCP servers, providing a single entry point to find tools. The database currently includes 1,998+ unique servers, automatically updated every 3 hours, with intelligent deduplication to avoid duplicates across sources. Features include semantic search with precomputed embeddings for sub-second responses, production-ready distribution via uvx/pipx, and security hardened with origin validation middleware. The project emphasizes developer-friendly workflows, complete documentation, and an automated release cycle, enabling easy deployment and experimentation for agents seeking MCP-based capabilities.
