Vercel MCP deployment lookup returns 403 after reconnecting

Hi, I’m having trouble using the Vercel MCP connection in ChatGPT with a team project.

The connection can identify my account and list the team, but a project lookup returned 404 and listing deployments returned 403. I reconnected and approved access, but the 403 continued. Saved deployment lookup requests included the team slug.

What should I check to determine whether the OAuth grant or the request’s team scope is causing this? I can provide request details privately to Vercel staff if needed.

Thank you!
