The source of all 44,805 server listings in this snapshot. Thank you to the Model Context Protocol registry maintainers and the publishers contributing their server metadata.
Imported · Deduplicated by server nameNeither this directory nor the embedded MCP Connect interface queries PulseMCP. Its listings are not included in the count above. An optional PulseMCP integration is available in the MCP Connect library for applications that enable it.
Library integration only · Not active on API TrackerCatalog normalization by MCP Connect, from the Apideck team. Registry membership and publisher verification are separate. Explore the public catalog API →
We review publisher documentation and match it to the exact server repository or endpoint. Community means reviewed third-party maintenance. Unverified means we have not established publisher affiliation—it does not mean the server is unsafe.
Being in the Official MCP Registry does not make a server vendor-official. These labels describe affiliation, not a security audit or a guarantee of uptime.
