Public MCP registry listing

passive · Category Protocols · Weight 10 · Key protocols.mcp_registry_presence

Searches the public MCP registries (the official registry.modelcontextprotocol.io and Glama) for the target. A hit requires a verifiable tie — a registry entry URL on the target host, or a server name under the target's reverse-DNS namespace (which the official registry verifies via DNS / GitHub). A listing in any registry earns full credit. Registry timeouts / blocks are a skip (not a fail) because they are our fetch problem, not the target's.
