Which MCP servers actually work?

We track 46253 servers from the official MCP Registry. 30004 are hosted (remote); we have health-checked 29735 so far. 273 use templated URLs that need user-specific values and can't be checked. Of those checked, 16445 passed a full MCP handshake, 8100 are up but need credentials, and 5190 failed or were unreachable (last check 2026-10-19T08:06:11.961Z UTC). How we check.
