Example Next.js

You are working with an MCP Server built for Next.js that routes prompts across a group of routes using the MCP handler. It enables you to expose an MCP endpoint through a Next.js project and test client invocations against that endpoint.

How to use

To use this MCP Server, point your MCP client at the provided HTTP endpoint. A sample client command demonstrates how to invoke the server for testing.

Important notes for running on Vercel: you can use the SSE transport when a Redis instance is attached to your project (set process.env.REDIS_URL). If you enable SSE, ensure the disableSse flag is set to false in your Next.js route configuration. For efficient execution, enable Fluid compute. If you are on a Vercel Pro or Enterprise account, you may adjust maxDuration to 800. Finally, deploy the Next.js MCP template to your project. The sample client shows how to invoke the server using a test script.

Sample client invocation you can try now is shown here. It targets a live MCP server URL and runs a test client script against it.
