AI agents call get_current_url to retrieve information from InSite without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply queries and returns the current URL of the active browser page. It performs no state changes, does not modify data, execute code, delete resources, or move money. It is a straightforward read operation with minimal blast radius—knowledge of the current URL poses no direct security risk.
