2337 connectors in this directory are remote MCP servers, and Claude can add a remote MCP server as a custom connector. 2307 answered our last check. The server is the same whichever assistant calls it; what changes is how you add it.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it.
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Each connector page shows its link under "Also use it in Claude".
Mostly, yes. Both are remote MCP servers, the same open standard Anthropic published. The server does not know which assistant is calling it. The exceptions are connectors built into Muse by Meta, which have no public link, and companies that block one assistant but not another.
No. We send every server a real MCP request every 15 minutes and show the answer. We cannot see whether your Claude plan lets you add custom connectors.
Because the server is the same. Set it up once in each assistant you use and the same tools are in both. Builders list once and are found by everyone.
Built a connector? List it once and it shows up for Muse, ChatGPT and Claude users, with a live status badge.
