The ChatGPT Vercel MCP connection recognizes the correct account, but lists zero teams and returns HTTP 403 when reading the existing team's projects or deployments with an explicit team scope. The same account is the team owner, and existing CLI access to those projects succeeds.

The Vercel dashboard displays the ChatGPT connection with team/project/deployment permissions. Reconnecting once did not resolve the issue. The error reports no SAML or SSO enforcement. No roles, credentials, deployment protection or security settings have been changed.

What is the smallest supported repair for the existing connector's resource authorization? Please advise how to provide request IDs privately if needed. Success would mean the originating connected assistant can list its authorized team and read a project and its production deployment.
