Dump and search Android UI hierarchy nodes by text or resource-id.
AI agents call android_find_ui to retrieve information from DevLab MCP Suite without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and searches UI hierarchy information from an Android device. It performs read-only operations (dump and search) on UI metadata without modifying state, executing code, or triggering device actions.
From the tool's definition Tool description explicitly states 'Dump and search Android UI hierarchy nodes by text or resource-id' — these are query and inspection operations with no modification, deletion, or execution of device functionality.
Attacks that exploit this kind of access
Dump and search Android UI hierarchy nodes by text or resource-id. It is categorised as a Read tool in the DevLab MCP Suite MCP Server, which means it retrieves data without modifying state.
Register the DevLab MCP Suite MCP server in PolicyLayer and add a rule for android_find_ui: 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 DevLab MCP Suite. Nothing to install.
android_find_ui 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 android_find_ui 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 android_find_ui. 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.
android_find_ui is provided by the DevLab MCP Suite MCP server (tanguito86/devlab-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
