Vercel MCP Server

Build quota exceeded or deployment fails from quota limits

Check quota usage at vercel.com/dashboard/usage. Plans have specific build time/memory limits. Upgrade plan for higher quotas. Optimize build scripts to reduce time. Review vercel.com/docs/limits for plan limits.

Deployment fails with missing environment variables

Add environment variables in Project Settings > Environment Variables. Set correct environment scope (Production/Preview/Development). Redeploy after adding variables. Check .env.local not committed to git.

API rate limit errors from third-party services

Implement rate limiting with Vercel WAF. Use Vercel KV/Redis for rate limit tracking. Check third-party API quotas not exceeded. Add delays between API calls. Use edge functions for caching.

Authentication failed or insufficient project permissions

Verify Vercel API token has required scopes. Check team membership and project access in Dashboard. Use team tokens for shared projects. Re-authenticate OAuth connection. Ensure token not expired or revoked.
