PulseMCP is a discovery and listing layer over the MCP ecosystem rather than an MCP server or API itself. Search, retrieve, and index compose well with other Leyline components; ingest is operationally gated and notify is a newsletter side-channel, so it is a useful catalog but not a runtime building block.
