MCP server tools now in ChatGPT -- developer mode

Great to see this support added!

It is failing 99% of the time though to call my MCP server. The list_resources call correctly finds the tools, but the response is almost always “The xyz tool isn’t available”, even though it absolutely does show in the list.

Very occasionally it works by being very explicit (call xyz tool on MyConnector) but mostly even that fails. It calls the tool but returns an error ResourceNotFound: not found: MyConnector/link_68c2f524b0088191beefa6b03ac93cf5/xyz

Is this just me or a common issue?
