Vercel MCP Server Template

# Run an MCP Server on Vercel ## Usage Update `api/server.ts` with your tools, prompts, and resources following the [MCP TypeScript SDK documentation](https://github.com/modelcontextprotocol/typescript-sdk/tree/main?tab=readme-ov-file#server). [There is also a Next.js version of this template](https://vercel.com/templates/next.js/model-context-protocol-mcp-with-next-js) ## MCP Client Integration When adding this server to an MCP client application, use your deployment URL followed by `/mcp`: ``` https://your-deployment-url.vercel.app/mcp ``` ## Example Tools The template includes two example tools to get you started: - **`roll_dice`** - Rolls an N-sided die (minimum 2 sides) - **`get_weather`** - Gets current weather data (via an API) for a location using latitude, longitude, and city name These tools demonstrate basic functionality and API integration patterns. Replace them with your own tools. ## Notes for running on Vercel - Make sure you have [Fluid compute](https://vercel.com/docs/functions/fluid-compute) enabled for efficient execution - After enabling Fluid compute, open `vercel.json` and adjust max duration to 800 if you using a Vercel Pro or Enterprise account - [Deploy the MCP template](https://vercel.com/templates/other/model-context-protocol-mcp-with-vercel-functions) ## Local dev - Run `vercel dev` for local development - Alternatively, integrate the system into the server framework of your choice. ## Sample Client `script/test-client.mjs` contains a sample client to try invocations. ```sh node scripts/test-client.mjs https://mcp-on-vercel.vercel.app ```
