weather_get_forecast
AI agents call weather_get_forecast to retrieve information from Weather MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves weather forecast data from the Open-Meteo API. It has no capability to modify, delete, execute code, or trigger external operations. The read-only nature of retrieving weather information poses minimal security risk even if misused by an AI agent—at worst, it could make excessive API calls, but the server uses a free API with no authentication required, limiting harm further.
From the tool's definition Tool name 'weather_get_forecast' and server description indicating it 'Provides weather data including current conditions, daily forecasts up to 16 days, and hourly forecasts up to 7 days' confirms this retrieves forecast data with no side effects.
