Hi Vercel Team and Community,
I am attempting to connect Vercel as a custom connector in Claude using the Vercel MCP endpoint because the normal connection stopped working and it's not letting me do it in any way:
During the OAuth authorization flow, after authorizing my Vercel account in the browser, the redirect fails and shows the following error message:
"Tu cuenta fue autorizada, pero Vercel devolvió un error al conectarse. Puedes intentarlo de nuevo o verificar que el servidor esté funcionando correctamente. Si esto persiste, comparte esta referencia con el soporte: ofid_b6618c465d50b361"
(Translation: "Your account was authorized, but Vercel returned an error when connecting. You can try again or check that the server is working properly. If this persists, share this reference with support: ofid_b6618c465d50b361")
Key details:
- Connector URL: https://mcp.vercel.com
- Application: Claude / Cowork Custom Connectors
- Reference Code: ofid_b6618c465d50b361
Could someone from the Vercel team or MCP product group check this trace/reference ID to see why the OAuth callback is failing?
Thank you!
