Overview
What is MCP example & Demo?
MCP example & Demo is a simple MCP server that demonstrates the Model Context Protocol. It implements a basic "add" tool and shows how to communicate with an MCP server over STDIN using JSON‑RPC messages.
How to use MCP example & Demo?
Run the server with mcp run server.py and send JSON‑RPC messages over STDIN. Alternatively, use mcp dev server.py to launch the MCP inspector for interactive testing.
Key features of MCP example & Demo
