MCP Server List
Every MCP server in the official registry that has something to show: 35 106 in total, of which 13 613 answered our last handshake and 8 180 are listed as active but do not respond. Sorted by uptime, real installs and the number of tools each one exposes — not by date added.
New to this? What an MCP server is, and what all 35 106 of them expose — written from our own handshakes, not from the specification.
