Good to know

Custom MCP servers depend on your ChatGPT plan and, in a workspace, on what an admin allows. Some accounts show this under Settings, then Apps and Connectors, with Developer mode switched on in Advanced settings: create a connector there with the same address and no authentication.

No key and no sign-in are needed. Each session is paced like the API: 60 domains a minute and 2,000 a day. The MCP tools page lists what ChatGPT can do with it.
