Vercel

This MCP server runs on Vercel and provides a lightweight dice-rolling tool you can access from any MCP client. It serves a simple API endpoint that evaluates dice rolls and returns the result, making it easy to integrate into chat apps, assistants, or automation workflows.

How to use

Connect to the MCP endpoint from your MCP client using either the HTTP URL or a local stdio runner. When you query the server with a roll request, you will receive a structured response that conveys the dice result in a readable format for display in your app or chat interface.

How to install

Prerequisites you need before starting: a modern Node.js runtime with npm installed.

Local development steps you can follow to run the MCP server on your machine:

Install dependencies

npm install

Run the development server

npm run dev

Access the MCP endpoint locally at: http://localhost:3000/api/mcp

Deploying to production on Vercel follows a standard workflow: push your code to a GitHub repository, connect it to Vercel, and deploy. After deployment, the MCP endpoint will be available at your project URL under /api/mcp.

Additional content

Server connection methods shown in this guide include both an HTTP endpoint and a local stdio runner. The HTTP URL is the primary access point for remote clients, while the stdio configuration enables running the MCP server as a local process that your MCP client can fetch from.
