arunsiv-weather-mcp-server

A Model Context Protocol (MCP) server that provides current weather data for any 5-digit US zip code.

Built with Python using the official mcp SDK, this server exposes a get_weather tool that can be used by AI assistants (like Claude) to dynamically retrieve weather conditions.

Features

• Zip Code Geocoding: Converts 5-digit US zip codes into latitude and longitude using the free Zippopotam API.
• Current Weather Data: Fetches the current temperature (°F) and wind speed (mph) using the free Open-Meteo API.
• Zero Configuration: No API keys are required to run this server.

pip install arunsiv-weather-mcp-server
