Notable MCP servers

8,684 servers tracked

Servers listed in the official MCP registry or in two or more of the sources we track, for which we also hold our own evidence: documented tools, an applicable advisory, or a review prompt from reading the source. It is a selection rule, not a recommendation — a server appears here because there is something to read about it, not because it is safe.
