Vercel MCP Server

Vercel

Vercel is a cloud platform for deploying and hosting modern web applications. This bundle provides access to projects, deployments, domains, environment variables, and teams.

Entity Hierarchy

• User/Team is the top-level scope. Resources belong to either a personal account or a team.
• Projects are the primary unit — each linked to a Git repository with its own deployments, domains, and environment variables.
• Deployments are immutable snapshots of a project. Each Git push or manual deploy creates a new deployment.
• Domains are custom hostnames assigned to production or preview deployments.
• Environment Variables are key-value pairs scoped to production, preview, or development environments.

Capabilities

Read operations:

• List teams and team members
• List projects with settings and linked repositories
• List deployments with status, URL, and build metadata
• Get deployment details including build logs
• List domains and their DNS configuration
• View environment variables (names and scoping)

Write operations:

• Create and update projects
• Trigger new deployments
• Add, update, and remove environment variables
• Add and configure custom domains

Workflows

Review deployment status: List recent deployments for a project to see build status (building, ready, error). Drill into a failed deployment to read build logs and identify the error.

Manage environment variables: List current env vars for a project grouped by environment. Add or update a variable, specifying which environments it applies to.

Configure a custom domain: Add a domain to a project, then configure DNS records as directed. Domain status updates once DNS propagates and SSL is provisioned.

Investigate a production issue: List recent deployments to find the current production deployment. Check build logs for errors. Compare with the previous deployment if a regression is suspected.

Gotchas

• Team vs personal scope: If the user belongs to teams, specify the team ID to access team projects. Without it, only personal projects are returned.
• Immutable deployments: Deployments cannot be modified after creation. To fix an issue, create a new deployment.
• Environment variable encryption: Secret values may be write-only (returned redacted). You can overwrite but not read the current value.
• Preview vs production: Each Git branch gets preview deployments. Only the production branch creates production deployments.
