Vercel MCP: get_project returns 404 although authenticated user/team and Dashboard project match

Hello Vercel team,

Vercel Support’s AI directed me to report this here because MCP is in Beta.

Using the official https://mcp.vercel.com/ endpoint through Codex in the VS Code extension, get_project returns HTTP 404 (“not_found / Project not found”) for an existing project visible in my Vercel Dashboard.

Verified:

OAuth reauthentication completed successfully.
After disabling/re-enabling the MCP connection, get_auth_user returned the expected user and matching default Team ID.
The Project ID and Team ID used in the request exactly match the IDs displayed in Dashboard settings.
Previous project-name lookups and a team-scoped project list also did not expose the project.

Request structure: get_project(idOrName="", teamId="")

Observed on October 19, 2026. Request ID: sin1:sfo1::9v9dm-1792402022775-6c5d3f2b5801

We stopped retries. No permissions, project settings, deployments or resources were modified.

Could you help determine whether this is an MCP resource-visibility/grant issue, request-routing issue, or a tool parameter requirement?

Please provide a targeted diagnostic step before suggesting broader permissions or configuration changes. I can provide exact account/team/project identifiers and screenshots through an official private channel if needed.

Our intended use is read-only inspection of project/deployment metadata and recovery topology.

Thank you.

Debugging 404 Errors

Sometimes things don’t go as expected when deploying a website. If you see a 404 on your site, that means the page or resource couldn’t be found. There are...

A human should be around soon to offer more advice. But you can also get helpful information quickly by asking v0.

Thank you. That guide primarily addresses 404 errors when accessing website/deployment URLs.

Our error occurs in the official Vercel MCP get_project tool, using the exact Project ID and Team ID shown in Dashboard settings. get_auth_user succeeds and returns the expected user and matching team.

We have already reauthenticated and refreshed the MCP connection. Please advise on MCP-specific resource visibility, effective grants or request routing, rather than website build output, rewrites or DNS changes.
