MCP.Pizza Chef: yunusemredilber

express-mcp-sse-server is an MCP server implementation that facilitates real-time, server-sent events (SSE) communication for Model Context Protocol workflows. It enables standardized, event-driven interaction between models and resources, supporting resource templating and management. Built on Node.js, it is ideal for applications requiring live updates and efficient context sharing with LLMs and other AI models.

README

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:

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:

yarn dev

This will run the server with the MCP inspector for debugging.

dev-ss

To start the server in production mode:

yarn start

By default, the server runs on port 3001. You can override this by setting the PORT environment variable:

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
