ChatGPT Vercel MCP returns 404 for existing project after reauthorization

I’m the Owner of the silent-visionary team.

I manually created openings-index-api in the Vercel dashboard. It exists and has no deployments yet.

ChatGPT’s Vercel connector returns: 404 Not Found — Project not found.

The lookup was tested with both the explicit team ID and team slug silent-visionary. Listing projects returns only land-mee.

I reauthorized ChatGPT for all current and future projects, completed reconnection, and repeated the read-only check in a fresh ChatGPT conversation. The 404 persists.

The team Integrations page shows no installed integrations. Vercel’s support assistant reports that it can find the project.

Please investigate this project-access discrepancy and advise what diagnostic information is needed. I can provide identifiers privately if required.

There's another community post with 404 debugging tips that might be helpful. Please give these solutions a try and let us know how it goes.
