What is the MCP SSE Server?
The MCP SSE Server is a real-time communication solution based on the Model Context Protocol. It uses Server-Sent Events technology to establish a persistent connection and enables the server to push real-time data to the client.How to use the MCP SSE Server?
You can deploy the server through simple installation steps, then establish a connection using the SSE endpoint and send instructions through the message endpoint.Applicable scenarios
Suitable for application scenarios that require real-time data updates, such as monitoring dashboards, real-time notification systems, collaborative editing tools, etc.Main features
MCP protocol implementationFully implements the Model Context Protocol standard, providing a standardized way to manage models and resources
SSE real-time communicationBased on Server-Sent Events technology, supports the server to push real-time data updates to the client
Resource template managementProvides a flexible resource template system for easy management and reuse of various resources
Advantages and limitations
Advantages
Lightweight implementation based on Node.js and Express framework
Support for the standardized MCP protocol with good compatibility
SSE technology is simple and efficient, suitable for most modern browsers
Limitations
SSE is one-way communication (server → client)
Requires modern browser support
Not as flexible as the WebSocket protocol
How to use
Install dependencies
