How are the scopes that the ChatGPT Connector requests when authorizing the MCP server determined?

I’m trying to connect to our MCP server using the Developer Mode of the ChatGPT Connector.

The MCP server is protected by OAuth 2 authorization. ChatGPT enters the authorization flow via DCR but doesn’t request any scopes. The required scopes are listed in scopes_supported at /.well-known/oauth-protected-resource.

How can I make the ChatGPT Connector request the required scopes?
