Get current weather conditions for a location. If no location is provided, will automatically detect location from IP address. Supports coordinates, city names, or zip codes.
AI agents call get_current_weather to retrieve information from OpenWeatherMap MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves weather information without creating, modifying, deleting, or executing any operations. It has no blast radius if misused by an AI agent—at worst, it returns weather data for unintended locations. Location detection from IP is informational only and causes no state changes.
From the tool's definition Tool description states it 'Get[s] current weather conditions' and 'fetch[es]' data without modifying any state.
