Description

This server wraps the Caiyun Weather API as a Model Context Protocol (MCP) tool, allowing agents to query realtime conditions, minute-level precipitation forecasts, hourly and daily forecasts, and weather alerts. It supports address-to-location lookup (via optional AMap key), multi-language responses, and metric/imperial units. Designed to be run locally or via NPX and integrated into MCP hosts such as Claude, it requires a Caiyun API key and optionally an AMap API key for geocoding.
