Get the URL of the current page
AI agents call browser_get_url to retrieve information from Playwright 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 and returns the current page URL, which is a read-only query operation. It does not modify, execute, delete, or move resources. The data exposed (a URL string) is already visible to the user via the browser interface, presenting minimal risk even if accessed by an AI agent.
From the tool's definition Tool name 'browser_get_url' and description 'Get the URL of the current page' indicate a simple retrieval operation with no side effects.
