AI agents call get-battery-info to retrieve information from MCP Appium Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of device battery status. It retrieves information without modifying, executing code, deleting data, or affecting financial systems. While it operates in a mobile automation context via Appium, the specific action is purely informational. The low severity reflects that battery information alone poses minimal risk even if misused by an AI agent.
From the tool's definition The tool name 'get-battery-info' and description 'Get the device battery information' indicate a query operation that retrieves device state without modification. No side effects or state changes are implied.

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Appium Server, 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.

Get the device battery information. It is categorised as a Read tool in the MCP Appium Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Appium Server 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 MCP Appium Server. 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 MCP Appium Server MCP server (rahulec08/appium-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
