What active_window does on Mcp Control Plane

AI agents call active_window to retrieve information from Mcp Control Plane without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why active_window is rated Low

This tool performs a read-only operation to query the currently active window's metadata (title and bounds). It has no capability to modify system state, execute commands, delete data, or perform financial transactions. The information returned is ephemeral window state that could be useful for monitoring or logging but poses minimal risk if retrieved by an AI agent.

From the tool's definition Tool name 'active_window' and description 'Return the current foreground window title and bounds' indicate a query operation that retrieves window state information without modification or side effects.
