# Example Next.js MCP Server This template uses [`mcp-handler` 2](https://www.npmjs.com/package/mcp-handler) and the MCP TypeScript SDK v2 to add a stateless MCP server to a Next.js App Router application. ## Usage Update `app/mcp/route.ts` with your tools, prompts, and resources following the [MCP TypeScript SDK v2 documentation](https://ts.sdk.modelcontextprotocol.io/v2/). Start the application and connect an MCP client to: ``` http://localhost:3000/mcp ``` ## Protocol support - The current 2026-07-28 MCP protocol is served natively. - Stateless clients using 2025-era Streamable HTTP are supported by the compatibility layer. - The deprecated HTTP+SSE transport is not supported. Redis is not required. ## Notes for running on Vercel - Requires Node.js 20 or later - Make sure you have [Fluid compute](https://vercel.com/docs/functions/fluid-compute) enabled for efficient execution - [Deploy the Next.js MCP template](https://vercel.com/templates/next.js/model-context-protocol-mcp-with-next-js) ## Sample Client `scripts/test-client.mjs` connects over Streamable HTTP, lists the available tools, and calls `echo`. ```sh pnpm test:client -- https://mcp-for-next-js.vercel.app ```
