What is the MCP SSE Server?
The MCP SSE Server is a server implementation based on the Model Context Protocol (MCP), which uses Server-Sent Events (SSE) technology to provide real-time data stream services. It allows clients to subscribe to and receive data updates pushed by the server through the SSE protocol.How to use the MCP SSE Server?
You can start the server via a simple command line and configure the transport protocol and base URL as needed. After the server starts, clients can connect to and receive real-time data through the SSE endpoint.Applicable scenarios
Suitable for application scenarios that require real-time data updates, such as real-time monitoring, instant notifications, data dashboards, etc. Particularly suitable for projects that need a lightweight real-time communication solution.Main features
Server-Sent Events support
Provides lightweight real-time data push functionality using the SSE protocol, suitable for Web application integration
Flexible configuration
Supports configuring the server address and port display options through command-line parameters
Scalability
Provides a basic framework that can be easily extended to integrate other services such as PostgreSQL and NATS
Advantages
Lightweight implementation with low resource consumption
Uses the standard SSE protocol, compatible with modern browsers
Simple configuration and easy to deploy
Provides reference implementations for actual use cases
Limitations
The SSE protocol is one-way communication, and the client cannot send data through the same connection
Requires modern browsers or clients that support SSE
Lacks a built-in authentication mechanism
How to use
Build the server
Build the server executable file using the Go toolchain
