Example Next.js MCP Server

Uses mcp-handler

Usage

This sample app uses the Vercel MCP Adapter that allows you to drop in an MCP server on a group of routes in any Next.js project.

Update app/[transport]/route.ts with your tools, prompts, and resources following the MCP TypeScript SDK documentation.

Notes for running on Vercel

  • To use the SSE transport, requires a Redis attached to the project under process.env.REDIS_URL and toggling the disableSse flag to false in app/mcp/route.ts

  • Make sure you have Fluid compute enabled for efficient execution

  • After enabling Fluid compute, open app/route.ts and adjust maxDuration to 800 if you using a Vercel Pro or Enterprise account

  • Deploy the Next.js MCP template

Sample Client

script/test-client.mjs contains a sample client to try invocations.

node scripts/test-client.mjs https://mcp-for-next-js.vercel.app

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
