Overview

What is Example MCP SSE Server?

Example MCP SSE Server is a Node.js implementation of the Model Context Protocol (MCP) that uses Server-Sent Events (SSE) for real-time communication. It provides a standardized way for applications to manage and communicate with models and resources.

How to use Example MCP SSE Server?

Clone the repository, run yarn install, then start the server with yarn dev (development, includes MCP inspector) or yarn start (production). The SSE endpoint is at /sse and the message endpoint at /messages. Change the default port (3001) by setting the PORT environment variable.

Key features of Example MCP SSE Server

Implements the Model Context Protocol (MCP)
Uses Server-Sent Events (SSE) for real-time communication
Provides resource templating and management
Simple development and production startup scripts

Use cases of Example MCP SSE Server

Real‑time model interaction in web applications
Standardized resource management across multiple clients
Prototyping and debugging MCP integrations using the built‑in inspector

Frequently asked questions

What are the runtime requirements?

Node.js v14 or higher and Yarn package manager are required.

What endpoints does the server expose?

`/sse` for establishing persistent SSE connections and `/messages` for sending messages to the MCP server.

How can I change the default port?

Set the `PORT` environment variable before starting the server, for example `PORT=5000 yarn start`.

What are the main dependencies?

The server uses the `@modelcontextprotocol/sdk` for MCP and Express as the web framework.

Can I run the server in production mode?

Yes, run `yarn start` to start the server in production mode without the MCP inspector.
