Vercel's handler for deploying MCP servers on the same serverless / edge infrastructure that powers Next.js. Lets you ship an MCP endpoint as a Route Handler with zero new ops. The standard path to production for TypeScript MCP servers (formerly mcp-adapter; the npm package is now mcp-handler).

What it does

  • Vercel's official handler for hosting MCP servers on serverless functions and edge runtime
  • MCP endpoints ship as Route Handlers — zero new infrastructure
  • The standard path for TypeScript MCP servers going to production

When to use it

When your local stdio MCP server needs a public URL — for a team, a hosted agent, or a customer demo — the adapter turns it into a deployable endpoint.

Getting started

npm install mcp-handler

Wrap your MCP server with the provided helper and export it as a Route Handler.

Things to know

Serverless is stateless — MCP servers that depend on long-lived local processes (stdio-spawned tools, in-memory state) need reworking to fit the request/response model.
