Which MCP servers actually work?

We track 47728 servers from the official MCP Registry. 31155 are hosted (remote); we have health-checked 30887 so far. 275 use templated URLs that need user-specific values and can't be checked. Of those checked, 16948 passed a full MCP handshake, 8557 are up but need credentials, and 5382 failed or were unreachable (last check 2026-10-21T14:46:13.150Z UTC). How we check.
