AI agents call puppeteer_screenshot to retrieve information from Server Puppeteer 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 visual state of a browser page without modifying any data or causing side effects. It retrieves/captures information but does not write, execute, or destroy anything.
