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, 23739 passed a full MCP handshake, 11763 are up but need credentials, and 4184 failed or were unreachable (last check 2026-11-08T11:00:28.417Z UTC). How we check.
