Find bus stops by location name, coordinates, or road name
AI agents call find_bus_stops to retrieve information from Singapore Location Intelligence MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about bus stop locations based on user-provided search criteria. It has no side effects, does not modify data, does not execute external commands, and does not move money. The blast radius of misuse is minimal — an agent could only retrieve public transportation location data that is already publicly available. This is a straightforward Read operation.
From the tool's definition Tool description states 'Find bus stops by location name, coordinates, or road name' — a pure query/search operation with no modification or execution of external operations. The verb 'find' indicates data retrieval.
