Which MCP servers actually work?

We track 59133 servers from the official MCP Registry. 40018 are hosted (remote); we have health-checked 39686 so far. 343 use templated URLs that need user-specific values and can't be checked. Of those checked, 23737 passed a full MCP handshake, 11763 are up but need credentials, and 4186 failed or were unreachable (last check 2026-11-08T14:55:20.619Z UTC). How we check.
