WHAT IT DOES

What list_all_windows does on AirMCP

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

RISK

Why list_all_windows is rated Low

This tool retrieves and enumerates system state (open windows) without modifying, deleting, or executing anything. It is purely informational. Severity is medium rather than low because window metadata (titles, app names, PIDs) can reveal sensitive information about user activity and running processes, which could be exploited by a malicious agent to infer user behavior or identify security-relevant applications.

From the tool's definition Tool name 'list_all_windows' and description 'List windows across all running applications with title, size, position, app name, and PID' indicate data retrieval only.
