WHAT IT DOES

What battery_status does on Mcp Control Plane

RISK

Why battery_status is rated Low

It is a pure read operation with minimal security impact—exposure would allow an agent to monitor device power status but not alter system behavior or access sensitive data beyond power metrics.

From the tool's definition Tool name 'battery_status' and description 'Return battery charge, health hints, and recent power state' indicate retrieval of device power information with no modification or execution capabilities.

battery_status Allowed

battery_status is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
