ChatGPT Vercel MCP returns empty projects and 404 with explicit team scope

Title: ChatGPT Vercel MCP returns empty projects and 404 with explicit team scope

My NABSOME team (slug: nabsome) has three active projects visible in the dashboard:

pro7f-website
pro7f-staging
web-app-nab-web

Vercel’s support assistant also confirmed these projects exist under the team.

The following MCP calls fail despite explicit team scope:

list_projects: {"teamId":"team_Kbb6WRweN7AAl7waA4QWs9Gn"}

Result: {"projects":[]}

get_project: {"teamId":"team_Kbb6WRweN7AAl7waA4QWs9Gn","projectId":"prj_kqxscwELtZFeh7ucvMHIcDU6zdQk"}

Result: 404 Not Found.

Using team slug "nabsome" also failed. list_teams successfully returns NABSOME. Reconnecting the ChatGPT Vercel connection did not resolve this.

How can I inspect or correct the OAuth team/project authorization? Could this be an MCP connector issue?
