About Example MCP SSE Server

What is Example MCP SSE Server: Real-Time, Ultra-Low-Latency Streaming?

Example MCP SSE Server is an open-source implementation of the Model Context Protocol (MCP) designed to enable real-time, ultra-low-latency data streaming via Server-Sent Events (SSE). This server provides a standardized way to manage model resources and establish persistent bidirectional communication channels, ideal for applications requiring instantaneous updates without the overhead of WebSocket protocols. It combines the efficiency of SSE with MCP's resource management capabilities to deliver seamless integration between backend models and client applications.

How to use Example MCP SSE Server: Real-Time, Ultra-Low-Latency Streaming?

To get started, first ensure you have Node.js (v14+) and Yarn installed. Clone the repository and install dependencies using the provided commands. For local development, run `yarn dev` to start the server with MCP inspector tools. In production, use `yarn start` and optionally set the PORT environment variable. Clients connect to the `/sse` endpoint for real-time streams, while the `/messages` endpoint handles command delivery. Transition between environments is straightforward thanks to the modular architecture.
