The Vercel connector is installed in ChatGPT and my Vercel account appears as connected and Primary. I have already disconnected/reconnected the integration and completed the Vercel OAuth authorization flow again. During OAuth, Vercel correctly shows my account/team and asks me to authorize ChatGPT. I granted the requested access, including the permissions presented by Vercel. However, when ChatGPT attempts to access Vercel through the connector, the MCP request still returns: 403 Forbidden — Not authorized The authorization appears successful in the UI, but MCP requests remain unauthorized. Steps already performed: 1. Confirmed that the Vercel connector is installed in ChatGPT. 2. Confirmed that the correct Vercel account is connected and shown as Primary. 3. Reconnected the Vercel account from ChatGPT. 4. Completed the Vercel OAuth authorization flow again. 5. Explicitly allowed the access requested by Vercel. 6. Confirmed that the Vercel dashboard itself is accessible normally. 7. Retested the connector after authorization. 8. The MCP connection continues returning HTTP 403. This therefore appears to be an authorization/token/scope issue between ChatGPT's Vercel MCP integration and Vercel rather than a normal Vercel dashboard access issue. Could the Vercel MCP engineering team please investigate whether the OAuth authorization/token or account/team scope is being correctly recognized after authorization? I can provide screenshots and any additional diagnostic information required. Thank you. Malltecs (@malltecs) · 2026-10-16 **Subject: Vercel connector remains unauthorized after successful reconnection** I am experiencing a persistent authorization issue with the Vercel integration in ChatGPT. My Vercel account, `eric@pmipros.com`, is shown as the primary connected account. I completed the Vercel authorization screen for the Malltecs team and granted the requested permissions. However, ChatGPT still cannot access my Vercel project, `education-foundation-reports-dashboard`. The connector returned: - **401 Unauthorized** when retrieving a deployment source file. - **403 Forbidden** when accessing the Malltecs team scope. I have reconnected the primary account and completed the authorization process again. The Vercel dashboard and my staging deployments remain accessible directly. I need to edit the HCEF staging report pages, but cannot proceed safely while the connector cannot read the source files. I do not want to change or promote production deployments. Please investigate whether the OAuth token and team-level authorization scope are being correctly recognized by the ChatGPT–Vercel integration.
