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:
cd hono-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.
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
