WHAT IT DOES

What get_active_window does on Allcanuse

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

RISK

Why get_active_window is rated Low

The tool appears to retrieve information about the currently active window, which is a read-only query operation with no side effects. The server context indicates system probing capabilities, and window state queries are typically information retrieval.

From the tool's definition Tool name 'get_active_window' suggests querying the active window state without modifying it. No description provided to contradict this interpretation.
