Sample code for Model Context Protocl (MCP) with Server Sent Event (SSE)

What is Sample code for Model Context Protocl (MCP) with Server Sent Event (SSE)?

This repository is a sample implementation of an MCP server using Server Sent Event (SSE) transport. It provides two simple, non‑useful methods (reverse text and uppercase) to help developers understand how an SSE‑based MCP server works. The server is based on the official simple-tool example from the modelcontextprotocol/python-sdk.

How to use Sample code for Model Context Protocl (MCP) with Server Sent Event (SSE)?

Launch the server with the uv command: uv run mcp_server_sample --port 8080 --transport sse. Then run the provided client script: python client.py.
