2337 connectors in this directory are remote MCP servers, and ChatGPT 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 need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Each connector page shows its link under "Also use it in ChatGPT".
Mostly, yes. Both are remote MCP servers, the same open standard. 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 do not hold accounts on every ChatGPT plan, so we cannot see whether yours lets you add custom connectors.
Because the server is the same. If you use more than one assistant, you set the connector up once in each and get the same tools 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.
