The support here is really weird.

If I understand correctly, it requires your MCP server to have exactly two tools - search and fetch.

So this is not really support for MCP in general, as in all the available MCP servers. It’s support for their own custom higher-level protocol built on top of MCP.

For ChatGPT and DeepResearch yes, not when using the API. I guess you could just return empty results if you want to offer other tools as well (can't test it now, since custom connectors only supports Workspace or PRO accounts for this moment).

Quote we're talking about: > To work with ChatGPT Connectors or deep research (in ChatGPT or via API), your MCP server must implement two tools - search and fetch.

Reference links:

- Which account types can setup custom connectors in ChatGPT: https://help.openai.com/en/articles/11487775-connectors-in-c...

Yeah I hope they open up support to all MCP tools - this is lame as-is.

this guide is just for an example of how to build a single mcp (e.g. a vector store). chatgpt connectors implement mcps in general now

I don’t believe this is the case. Do you have a link for that?

Also, this page is actually the only docs site about MCP they have, and their help articles link to it too.
