指定した都市の降水確率を取得します
AI agents call get_precipitation_probability to retrieve information from MCP-Weather without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves weather data (precipitation probability) for a specified city from the Japan Meteorological Agency API. It performs a simple query operation with no capability to modify, delete, execute code, or create financial obligations. The read-only nature and non-sensitive weather data result in low severity risk.
From the tool's definition Tool name 'get_precipitation_probability' and description '指定した都市の降水確率を取得します' (retrieve precipitation probability for specified city) indicate data retrieval with no modification or side effects.
