AI agents call get_orientation to retrieve information from uiautomator2 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to retrieve the current screen orientation of an Android device, which is a read-only operation that queries state without modifying or executing anything. The empty description and reliance on naming convention moderately reduces confidence, but the 'get_' prefix and lack of side-effect keywords support Read classification. Severity is low as reading orientation state poses minimal security risk.
From the tool's definition Tool name 'get_orientation' suggests querying device orientation state. No destructive, financial, or execution keywords present.
Documented attack patterns abuse exactly the kind of access get_orientation gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and uiautomator2 MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_orientation:
{
"version": "1",
"default": "deny",
"tools": {
"get_orientation": {}
}
}get_orientation is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_orientation. It is categorised as a Read tool in the uiautomator2 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the uiautomator2 MCP Server MCP server in PolicyLayer and add a rule for get_orientation: 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 uiautomator2 MCP Server. Nothing to install.
get_orientation 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_orientation 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_orientation. 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_orientation is provided by the uiautomator2 MCP Server MCP server (tanbro/uiautomator2-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from uiautomator2 MCP Server, 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.
