AI agents call get_battery_info to retrieve information from Adb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries battery information from an Android device via ADB. It has no side effects—it only retrieves existing data about the device's power state. This is a pure read operation with minimal security impact, as battery information is non-sensitive system metadata that does not provide access to user data, financial systems, or destructive capabilities.
From the tool's definition Tool name 'get_battery_info' and description '获取电池信息' (get battery information) indicate a read-only operation that retrieves device battery status without modifying or executing any actions.
Documented attack patterns abuse exactly the kind of access get_battery_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Adb, and nothing reaches the server without passing your rules. This is the rule we recommend for get_battery_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_battery_info": {}
}
}get_battery_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取电池信息. It is categorised as a Read tool in the Adb MCP Server, which means it retrieves data without modifying state.
Register the Adb MCP server in PolicyLayer and add a rule for get_battery_info: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Adb. Nothing to install.
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 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 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.
get_battery_info is provided by the Adb MCP server (wolfcoming/adb_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Adb, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
