Weather MCP Server

A Model Context Protocol (MCP) server that provides weather forecasts and geocoding lookup using the free, keyless Open-Meteo APIs. This server enables LLMs (like Claude, Gemini, and GPT) to query real-time weather information and multi-day forecasts for any city or location in the world.

Features

• Get Current Weather: Detailed current conditions including condition description, temperature, apparent temperature (feels like), humidity, wind speed, and precipitation details.
• Multi-day Weather Forecast: Standard 1-7 day forecast with conditions, daily min/max temperatures, and total expected precipitation.
• Keyless & Free: Powered by the open-source Open-Meteo APIs, requiring no API keys or subscription signups.
• Fuzzy Geocoding: Automatically resolves location names (e.g., "Paris", "New York", "London") to geographic coordinates and timezones.
