A reference implementation demonstrating the Model Context Protocol (MCP) using Cloudflare Workers and Durable Objects.

We create an MCP server in a Durable object using DurableMCP and expose a web frontend that can connect call those endpoints.

This repository provides a reference implementation of MCP over WebSockets. It showcases:

• Complete MCP client-server architecture
• Tool discovery and invocation
• Deployment using Cloudflare Workers

Install dependencies:

pnpm install

Start the development server with:

pnpm run dev

Your application will be available at http://localhost:5173.

npx deploy
