Manage deployments, projects, domains and application infrastructure on Vercel. Automate releases, monitor environments and operate modern web applications.
ChatGPT is OpenAI's assistant. It can add custom MCP servers as plugins, which lets it call your tools from a conversation.
This guide connects Vercel to ChatGPT through MewCP, so ChatGPT can use Vercel's 20 tools, like health_check, list_vercel_api_calls and list_projects, without your Vercel credentials ever reaching the app.
Your Vercel API key is stored encrypted and injected only at call time. Your agent never holds it, so it can never leak it, log it or paste it into a prompt.

Other clients
Vercel works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Vercel tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
