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

Vercel MCP in ChatGPT cannot access an existing team project.Vercel Support directed me to Community for a Vercel MCP beta issue. An existing team-owned project is accessible in the authenticated Vercel dashboard but cannot be found through the connected Vercel app in ChatGPT. The connected Vercel account matches the dashboard account.

Observed behavior: list_teams returns the correct team. list_projects with the verified team ID explicitly supplied in teamId returns {"projects":[],"pagination":{"count":0}}. Retesting with the verified team slug in teamId also returns an empty list. get_project with the verified project ID/name and explicit team scope returns 404 Project not found. Disconnecting and reconnecting the integration and verifying the account did not resolve it.

Expected: access to projects within the authorized team scope, consistent with dashboard access. This is a connector project-lookup issue, not a deployed website returning 404.

Could engineering investigate team-scope propagation, project-access grants, or connector routing? If a different parameter schema or authorization step is required, please clarify the exact supported flow. Missing teamId alone does not explain these tests: it was explicitly provided.

Private identifiers and credentials are omitted. Please provide a secure channel if engineering needs identifiers.
