Capture screenshot of current page or specific element
AI agents call capture_screenshot to retrieve information from MCP Connect without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves visual information from a browser or simulator without creating, modifying, deleting, executing code, or triggering external actions. It is purely observational—a read operation with minimal risk. The low blast radius reflects that screenshot capture cannot damage data, move money, or cause unintended system changes.
