Aggregated from the official MCP Registry, Smithery, PulseMCP and other public registries, plus our own crawling and operator submissions. Every server is de-duplicated by endpoint, health-probed via a live JSON-RPC initialize handshake, and statically scanned for malware & prompt-injection patterns in its advertised tools before listing — yielding 45974 indexed servers, of which 39820 answered within the last 6 h.
