AI agents call xpath_get_attrib 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.
Despite the empty description, the naming convention strongly suggests this is a read-only operation that retrieves attribute values from UI elements on an Android device. No side effects or state changes are implied. The 'get' verb and attribute retrieval purpose are consistent with information retrieval operations.

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 xpath_get_attrib:
{
"version": "1",
"default": "deny",
"tools": {
"xpath_get_attrib": {}
}
}xpath_get_attrib is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

xpath_get_attrib. 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 xpath_get_attrib: 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.

Yes. Add a rate_limit block to the xpath_get_attrib 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 xpath_get_attrib. 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.
xpath_get_attrib 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.
