ChatGPT Vercel MCP: 403 on project creation and 404 on lookup after team authorization

Hello Vercel team,

The official support flow directed this Vercel MCP issue to the Community.

I’m using the Vercel connection in ChatGPT with the team phone-price-site.

An attempt to create a separate new project through the MCP returned HTTP 403.
Afterward, an empty project named project-tbdqn was created, but looking up that existing project through the MCP returned HTTP 404.
The problem persisted after completing the official team-access authorization flow.

Could you help identify which permission or connection setting is causing this, and the supported steps to restore access? The project-creation failure and the lookup failure concern different projects.

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.
