Overview

mcp-weather is a Model Context Protocol (MCP) server that provides hourly and daily weather forecasts using the AccuWeather API. It allows large language models, like Claude, to access real-time weather data. The server fetches accurate, up-to-date forecasts, supplying both metric and imperial unit data for temperature, conditions, precipitation, and more. Tools included are the hourly weather forecast tool, 'weather-get_hourly', and the daily weather forecast tool, 'weather-get_daily', facilitating users to access relevant information. Prerequisites for usage are Node.js 18 and an AccuWeather API key, set via .env or the user's shell. For integration with Claude Desktop and other MCP-compatible clients, MCP server configuration is available, enabling users to utilize the server with their preferred clients and access weather data within their conversations.
