Matching resolves 5,975 declarations into 5,138 distinct repository-server pairs. Provenance separates directory claims from live probing and records how declarations were matched. The public dataset enables ecosystem research and schema inspection, but its use of candidate projects and inferred links means the numbers are not a census of verified, active or safe MCP deployments.",
