AI agents call maps_around_search to retrieve information from 高德地图 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a nearby search query based on location coordinates and keywords to retrieve points of interest (POI). It only reads and returns data from the map service with no side effects, modifications, or destructive actions. The search operation is purely informational and retrieves existing data without altering any state.
