Find an image on the screen and return its coordinates
AI agents call find_image_on_screen to retrieve information from Mcp Windows without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs screen analysis to locate images and return position data. It is purely observational with no side effects—no data is created, modified, deleted, executed, or financial transactions initiated. The blast radius of misuse is minimal; an attacker could gain knowledge of screen layout but cannot directly execute actions or access sensitive data beyond what is visually displayed.
From the tool's definition Tool name 'find_image_on_screen' and description 'Find an image on the screen and return its coordinates' indicate a query/detection operation that retrieves visual information without modifying system state.
