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 implementation
