Which MCP servers actually work?

We track 46141 servers from the official MCP Registry. 29920 are hosted (remote); we have health-checked 29653 so far. 271 use templated URLs that need user-specific values and can't be checked. Of those checked, 16421 passed a full MCP handshake, 8068 are up but need credentials, and 5164 failed or were unreachable (last check 2026-10-18T22:30:54.707Z UTC). How we check.
