Since 2026-08-12 evening (Paris time), my MCP connection to https://mcp.vercel.com has been failing consistently with an HTTP 500 error. Still happening as of 2026-08-13.

Context

• Client: Claude Code (official plugin:vercel:vercel plugin)
• Team ID: team_OVcEMyt8tpfN8l54vbSCsj7x
• Project ID: prj_DBAKs8mKiCdUyiuyTxOrlXWK0DS2
• Vercel CLI: 56.3.1 (Node.js 24.14.0)

Troubleshooting already tried, no effect

1. Simple reconnect via /mcp in Claude Code → HTTP 500
2. Cleared credentials and re-authenticated via OAuth → HTTP 500
3. vercel mcp --clients "Claude Code" --non-interactive (regenerated local MCP config) → config recreated successfully, but reconnect still fails after restarting the client
4. Local project already linked (vercel link in place, .vercel/project.json present with the correct projectId)

The public status page (vercel-status.com) shows no ongoing incident, so this looks account/token-specific or specific to this MCP endpoint. Anyone else seeing this, or any Vercel team member able to take a look?
