# Example MCP SSE Server A Model Context Protocol (MCP) server implementation, enabling server-sent events (SSE) based communication. ## Overview Example MCP SSE Server provides a Model Context Protocol implementation that allows for real-time communication using Server-Sent Events (SSE). It's designed to work with applications and provides a standardized way of managing and communicating with models and resources. ## Features - Model Context Protocol (MCP) implementation - Server-Sent Events (SSE) for real-time communication - Resource templating and management ## Prerequisites - Node.js (v14 or higher recommended) - Yarn package manager (can be changed easily) ## Installation Clone the repository and install dependencies: ```bash git clone git@github.com:yunusemredilber/express-mcp-sse-server.git cd express-mcp-sse-server yarn install ``` ## Usage ### Starting the Server To start the server in development mode: ```bash yarn dev ``` This will run the server with the MCP inspector for debugging.  To start the server in production mode: ```bash yarn start ``` By default, the server runs on port 3001. You can override this by setting the `PORT` environment variable: ```bash PORT=5000 yarn start ``` ### Endpoints - `/sse` - SSE endpoint for establishing persistent connections - `/messages` - Endpoint for sending messages to the MCP server ## Project Structure - `src/index.ts` - Main entry point of the application - `src/mcp-server.ts` - Implementation of the MCP server and resource definitions - `src/sse-server.ts` - SSE server implementation using Express ## Dependencies - [@modelcontextprotocol/sdk](https://www.npmjs.com/package/@modelcontextprotocol/sdk) - SDK for Model Context Protocol - [Express](https://expressjs.com/) - Web framework for Node.js
