Overview

What is Model Context Protocol (MCP)?

A working demo of the Model Context Protocol integrated with Google’s Gemini. It provides a server that uses SSE (Server-Sent Events) to expose MCP endpoints, alongside a FastAPI backend and a Streamlit GUI for interacting with the system.

How to use Model Context Protocol (MCP)?

Clone the repository, set a GOOGLE_API_KEY in a .env file, install dependencies with pip install -r requirements.txt, then start the MCP server with python sse_server.py (defaults to http://localhost:8080/sse). Optionally launch the SSE client with python ssc_client.py http://localhost:8080/sse, start the FastAPI server with python fastapp.py, and finally run the Streamlit app with streamlit run app.py (opens on localhost:8501). Click “Connect to MCP server” in the browser.
