Get battery information from the device
AI agents call adb_get_battery_info to retrieve information from ADB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves battery status information from an Android device without side effects. It is a pure read operation that queries device state, analogous to 'get' or 'fetch' operations. No data is modified, executed, or deleted. The information retrieved (battery level, temperature, health, etc.) is not sensitive enough to warrant a higher severity.
From the tool's definition Tool name: 'adb_get_battery_info'; description: 'Get battery information from the device' — both indicate a query/retrieval operation with no modification or execution of code.

adb_get_battery_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the adb_get_battery_info rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for adb_get_battery_info. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
