This is a sample MCP server implementation using Server-Sent Events (SSE) to demonstrate the capabilities of the Model Context Protocol.
The MCP SSE Sample is a demonstration project showcasing the implementation of the Model Context Protocol (MCP) using Server-Sent Events (SSE). It provides a variety of tools and features to illustrate how MCP can be utilized for different operations, including message echoing, arithmetic operations, long-running tasks, and LLM sampling. The project also includes a logging mechanism that sends random-leveled log messages every 15 seconds, providing insights into server operations. This sample is designed to help developers understand and implement MCP in their own projects, offering a practical example of how to handle different types of requests and responses using SSE.
