MCP servers

An MCP server is something you connect an agent to. The registry will tell you a server's name, its version and how to reach it — but not what it can do, which is the only thing you actually want to know. We read that off the repository.

31,279 servers, 76,670 tool names across 6,537 of them, last read 11 September 2026.

A server's tools are not in the registry. We read them from the repository README, which means a list here is what the README documented and an absence is usually silence rather than a server with nothing to offer: 20.9% of servers have a list, and filtering on tools narrows to those. Where a list exists, the page for the server says which part of the README it came from.

Live servers only. The whole corpus is one call away through the search API — including tools=, which is how you ask for a server by what it does rather than by what it is called.
