Return the current page URL (full URL with query/fragment).
AI agents call browserbase_stagehand_get_url to retrieve information from Browserbase 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 the current URL from an active browser session. It is a read-only operation that queries state without modifying, executing, or destroying anything. The worst case is an agent learning what page is currently loaded, which poses minimal risk. Severity is low because the information exposed (a URL) is typically non-sensitive in isolation and the tool has no capability to perform actions.
From the tool's definition Tool name and description indicate it 'Return the current page URL' — a pure query operation with no side effects, no data modification, no code execution, and no destructive actions.
