Claude Code Vercel Integration

Log in to Vercel

Required before Claude Code can deploy or read project metadata on your behalf.

Pull project settings and environment

Syncs settings and environment variables locally so a prebuilt build matches production.

Build for production locally

Produces the same build artifact Vercel would generate, useful before a prebuilt deploy.

Deploy a prebuilt artifact to production

Ships the locally built output, bypassing the remote build step for faster, deterministic deploys.

Manage environment variables

Add, list, or remove variables per environment; never paste secret values into a prompt.

Add or inspect a custom domain

Attaches a domain to the project and lists the DNS records you need to configure.

Deploy this project to Vercel using the CLI. First confirm which project and team it is linked to, run a production build, deploy it, then report the deployment URL and build status. Do not deploy to production until I confirm the target is correct.

Create a preview deployment for the current branch on Vercel and give me the preview URL. Summarize what changed on this branch so I know what to test when I open it.

Here is the failed Vercel build log. Trace the error to its root cause in the code or configuration, explain what is actually breaking, propose the smallest correct fix, then apply it and redeploy a preview so we can confirm it passes.

The build is failing because an environment variable is missing or wrong. Identify which variable the app expects, which environments it is missing from, and how to set it with the vercel CLI. Do not print any secret values in your response.

The latest production deployment is broken. Find the most recent healthy deployment, explain how to promote it back to production, and walk me through confirming the rollback succeeded before we announce it.

I want to attach this custom domain to the project on Vercel. Add the domain, list the exact DNS records I need to configure at my registrar, and confirm the domain will point at the current production deployment once DNS propagates.

This repository is a monorepo and the wrong app is deploying. Help me set the correct root directory, build command, and output directory for the app I want to ship so Vercel builds the right package.

Confirm which framework this project uses and whether Vercel's detected preset, build command, and output directory are correct for it. If anything is wrong for this stack, tell me the exact settings to change.

Generate a GitHub Actions workflow that deploys this project to Vercel. Use vercel pull to fetch settings, vercel build to produce a prebuilt artifact, and vercel deploy prebuilt to ship it. Trigger previews on pull requests and production on merges to the main branch.

A serverless function on Vercel is failing at runtime. Here is the function code and the runtime log. Identify the cause, explain how the failure happens, and propose a fix along with any region or runtime configuration I should change.

Pages or assets on this Vercel deployment are being cached in a way I did not intend. Review the cache headers and revalidation settings, explain the current behavior, and recommend the configuration that gives me the caching I actually want.

Audit this project's Vercel configuration. Review the build command, output directory, install command, root directory, and any vercel.json settings, then flag anything that does not match how this app is meant to build.

Here is the Speed Insights and analytics output for this project. Identify the slowest routes and the heaviest assets, explain what is likely causing the slowness, and give me a prioritized list of changes that would improve the numbers.

My deploy is being blocked with a team or seat access error on Vercel. Explain what the error means, identify the exact scope or permission that is missing, and tell me the least-privilege change needed to unblock the deploy.

I have verified this preview deployment and want to ship exactly this build. Explain how to promote this specific preview deployment to production without triggering a new build, so what I tested is what goes live.

Set up my local environment to match Vercel. Use vercel pull to fetch the settings and environment variables for the environment I name, explain what file it writes, and remind me to keep that file out of version control.

My app behaves differently on the Vercel preview than in production. Compare the two environments, focusing on environment variables, build settings, and caching, and explain the most likely reasons for the difference.

I need to ship a change that touches configuration and could break production. Plan a safe deploy: what to verify on a preview first, how to promote, how to watch for errors after release, and how to roll back quickly if something goes wrong.

Help me use Vercel preview or a separate project as a staging environment for this app. Explain how to route a stable staging URL, which environment variables to scope to it, and how to keep staging separate from production data.

Review this project for environment variable mistakes: variables that should be server-only but are exposed to the client, missing values in one environment, and anything that looks like a committed secret. Do not print secret values, only their names and where they are used.

What is the Claude Code Vercel integration?

It is a workflow that lets Claude Code work directly with your Vercel projects. Claude Code can run the vercel CLI to deploy, create preview deployments, manage environment variables, read and debug failed build logs, configure domains, and roll back releases, using your Vercel project as the source of truth. It enhances your existing deployment workflow rather than replacing it.

How do I deploy an app with Claude Code and Vercel?

Install and authenticate the Vercel CLI with vercel login, link the project with vercel link, then ask Claude Code to build and deploy. It can run a preview deployment first, confirm the URL, and only promote to production once you approve. For cross-project access, connect the Vercel MCP server instead of relying on the local CLI alone.

Can Claude Code create Vercel preview deployments?

Yes. Claude Code can run a preview deployment for a branch or pull request and return the preview URL so you can open the running app and test the change end to end. Reviewing a live preview before promoting is the safest way to catch problems that a diff alone would miss.

Can Claude Code debug a failed Vercel build?

Yes. Share the failed build log with Claude Code and it will trace the error to the file, dependency, or missing environment variable that caused it, explain what broke, and propose the smallest correct fix. It can then redeploy a preview so you confirm the build passes before shipping.

How does Claude Code manage Vercel environment variables?

Claude Code can add, list, and pull environment variables per environment with the vercel CLI so development, preview, and production each have the right values. It references secrets by name rather than printing them, and it reminds you to keep the pulled environment file out of version control.

Can Claude Code roll back a bad Vercel deployment?

Yes. When a release misbehaves, Claude Code can help you find the most recent healthy deployment and promote it back to production, reducing the time the issue is live. It walks you through confirming the rollback succeeded before you consider the incident resolved.

Can Claude Code set up CI/CD with Vercel and GitHub Actions?

Yes. Claude Code can generate a GitHub Actions workflow that uses vercel pull to fetch settings, vercel build to create a prebuilt artifact, and vercel deploy prebuilt to ship it, running previews on pull requests and production on merges. You keep control of which branch deploys where and which secrets the workflow can use.

Does the Vercel integration work in a monorepo?

Yes. Claude Code can set the correct root directory, build command, and output for the specific app inside a monorepo so the intended package deploys instead of the wrong one. This is one of the most common causes of a deploy shipping unexpected output, and it is quick to fix once the root directory is correct.
