Setup and observed behavior: * Existing Vercel Pro team: etome24 * Two existing Vercel OAuth connections in ChatGPT * Both connections authenticate, but list_teams returns an empty list (teams: []). * Requests to the team scope return 403 Forbidden. * The error says the requested scope is not authorized and requires re-authentication or a token with access to that scope. * Reconnecting has not resolved the issue. The team ID reported during a failed request is team_LkWPae5gyZxkBWLILdl79Cn. Could you please help determine why the OAuth grant does not include the existing team scope and how to authorize the correct team? We do not want to create a new project or account to work around this issue. Production safeguards: Our production website, DNS, CARNET configuration, and GitHub main branch must remain untouched. We are only requesting help with MCP team authorization. Thank you.
