Gets the current weather.
AI agents call get_weather to retrieve information from Google Maps 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 weather data and returns information without modifying, deleting, or executing any operations. It has no ability to alter state, trigger external actions, or cause financial impact. The low severity reflects minimal security risk from misuse—incorrect weather queries cause no harm to systems or data.
