What are you connecting to?
A server exposes MCP capabilities to a client. A framework or SDK helps you build one; a curated list helps you discover them. Some projects do both. Reviewed classifications link to their source. Other server labels reflect declared registry transports, not an independent audit.
Local means stdio is documented. Missing connection information stays unknown. The remote explorer is offered for public HTTPS endpoints with Streamable HTTP; authentication and browser access may still require publisher setup. We never generate install commands from names.
What does “official” mean?
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.
