Which MCP servers actually work?

We track 50499 servers from the official MCP Registry. 33342 are hosted (remote); we have health-checked 33057 so far. 294 use templated URLs that need user-specific values and can't be checked. Of those checked, 20015 passed a full MCP handshake, 9309 are up but need credentials, and 3733 failed or were unreachable (last check 2026-10-26T08:35:13.178Z UTC). How we check.
