Which MCP servers actually work?

We track 45729 servers from the official MCP Registry. 29589 are hosted (remote); we have health-checked 29334 so far. 259 use templated URLs that need user-specific values and can't be checked. Of those checked, 16259 passed a full MCP handshake, 7957 are up but need credentials, and 5118 failed or were unreachable (last check 2026-10-18T09:00:35.812Z UTC). How we check.
