search_by_location_point_distance
AI agents call search_by_location_point_distance to retrieve information from MLIT Data Platform MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description, the tool name and context strongly indicate this performs a distance-based location search returning data from Japan's MLIT Data Platform. This is a read-only query operation with no side effects. Severity is low because data retrieval from a public government platform poses minimal risk even if misused by an agent.
