Get names of all planning areas in Singapore.
AI agents call get_planning_area_names to retrieve information from OneMap 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 static geographic reference data (planning area names) from Singapore's OneMap API. It performs a read-only query with no side effects, no data modification, no code execution, and no financial implications. The blast radius of misuse is minimal—an AI agent could only retrieve publicly available geographic nomenclature.
From the tool's definition Tool name 'get_planning_area_names' and description 'Get names of all planning areas in Singapore' indicate a simple data retrieval operation with no modification, deletion, or execution of commands.
