Get a hierarchical view of the UI elements (similar to Appium Inspector)
AI agents call get-element-tree 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 queries and returns the UI element tree structure from the mobile app without performing any actions that modify app state, execute code, delete data, or trigger external operations. It is purely informational, similar to inspecting DOM elements in a browser developer tool.
From the tool's definition Tool description states it 'Get[s] a hierarchical view of the UI elements' — this is a retrieval operation with no modification or side effects. The comparison to 'Appium Inspector' (a view-only inspection tool) further confirms read-only behavior.
Documented attack patterns abuse exactly the kind of access get-element-tree gives an agent:
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-element-tree:
{
"version": "1",
"default": "deny",
"tools": {
"get-element-tree": {}
}
}get-element-tree is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a hierarchical view of the UI elements (similar to Appium Inspector). 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-element-tree: 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-element-tree 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-element-tree 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-element-tree. 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-element-tree 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.
