WHAT IT DOES

What get_brightness does on AirMCP

AI agents call get_brightness 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 get_brightness is rated Low

This tool retrieves display brightness information only. It performs no write, execute, destructive, or financial operations. The read operation has minimal security impact—brightness level is non-sensitive system metadata. Confidence is high because the description is clear and unambiguous.

From the tool's definition Tool name and description indicate a query operation: 'Get the current display brightness level.' This retrieves system state without modification, side effects, or external operations.
