Take screenshots of pages
AI agents call screenshot to retrieve information from MCP Playwright Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Taking a screenshot is a read-only operation that captures the current visual state of a browser page. It has no side effects on the page or any external system. The only concern is that it could capture sensitive information displayed on screen, but the action itself is non-destructive and reversible.
From the tool's definition 'Take screenshots of pages' — captures visual state of the page without modifying anything
