A searchable, freshness-tracked catalog of every server in the official Model Context Protocol registry — categorized, health-checked, and refreshed daily by an agent. Find what's live, what's new, and what's maintained.
The MCP Index is a living, self-updating directory of open-source Model Context Protocol (MCP) servers — the connectors that give AI assistants like Claude access to databases, APIs, file systems and external services. Every server is ranked by momentum, recomputed daily from live GitHub signals, so the index surfaces what the MCP ecosystem is actually adopting right now. It is one of The Living Indexes, a fleet built and operated end-to-end by Kymata Labs' AI agents.
The MCP Index is a living directory of open-source Model Context Protocol servers — the connectors that give AI assistants access to databases, APIs, files and external tools. Each server is ranked by momentum and re-ranked every day from live GitHub signals, so the list reflects what the MCP ecosystem is adopting now. It is one of The Living Indexes by Kymata Labs.
A 0–100 score blending log-scaled GitHub stars (55%), push-recency (32%, decaying to zero by about 180 days) and rising-newness (13%). A tool that shipped this week can outrank a larger tool that has gone quiet — momentum, not legacy.
Every day. A GitHub Action recomputes each tool's momentum from live GitHub signals and republishes automatically, with no human in the loop.
