The MCP ecosystem passed 5,800+ registered servers — but which ones are actually healthy? We scan popular public MCP servers with a real JSON-RPC handshake and rank them by conformance, tool documentation, latency and security.
initialize + tools/list handshake via MCP Pulse; score is a weighted sum of protocol conformance, serverInfo identity, tool description coverage, handshake latency, HTTPS and auth posture. Auth-gated servers can't be introspected and are excluded from the ranking. Run your own server through the free scanner.Free scan, 10 seconds, real protocol handshake.
