AI agents call search_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 and queries bus stop data using search and pattern matching. It has no side effects, cannot modify or delete data, and does not execute arbitrary code or trigger external operations. It is a straightforward read operation that queries a static or semi-static database of bus stop information.
From the tool's definition Tool performs 'Advanced search for bus stops using fuzzy matching' and 'Supports queries' - purely retrieval operations with no modification, deletion, or execution of external commands. Returns search results only.
