MCP Weather Tools – LLM Tool Calling Demo

This project implements an MCP (Model Context Protocol) Server and Host that enable an LLM client (such as Claude Desktop) to call a structured tool (get_weather) to retrieve real-time weather information from the Open-Meteo API.

It demonstrates practical experience with:

  • MCP Server/Client communication
  • Tool schemas and structured LLM responses
  • Python-based service orchestration
  • Real-time API integration
  • LLM-driven agent workflows
  • GUI integration using Tkinter

🚀 Running the MCP Server

cd server
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

python server.py

When started successfully, the console will show:


[MCP-Server] listening on 127.0.0.1:8787

🖥 Running the GUI Host


cd host
python -m venv .venv
source .venv/bin/activate

python host_gui.py

The GUI allows you to:

  • Connect to the MCP server
  • Enter a city (e.g., "Montevideo")
  • Fetch real-time weather data
  • Enable auto-refresh to retrieve updates periodically
