We track 45543 servers from the official MCP Registry. 29420 are hosted (remote); we have health-checked 29165 so far. 259 use templated URLs that need user-specific values and can't be checked. Of those checked, 16218 passed a full MCP handshake, 7845 are up but need credentials, and 5102 failed or were unreachable (last check 2026-10-18T00:25:42.256Z UTC). How we check.
