The official Vercel connector in ChatGPT can retrieve my user information, but listing teams returns an empty list. Listing projects with the correct team ID returns HTTP 403. I use the Hobby plan. The same account can access the team and projects as Owner in the Vercel dashboard. I verified the account and default team and reauthorized OAuth, but the issue persisted on October 18, 2026, at 15:29 JST. This is the installed ChatGPT connector, not a custom MCP setup. Vercel’s private support chat directed me here. How can I diagnose and restore the connector’s team access?
