WHAT IT DOES

What ui_find does on Claude Mobile

AI agents call ui_find to retrieve information from Claude Mobile without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why ui_find is rated Low

This tool retrieves information about UI element locations and properties without causing any side effects, state changes, or triggering device actions. It is purely informational and analogous to a search or query operation. While it operates in the context of mobile device automation, the specific function is limited to discovery and inspection, making it a Read category tool with low severity.

From the tool's definition The tool 'ui_find' performs a query operation to locate UI elements by text, resourceId, className, or label. The description explicitly describes finding/locating elements with no modification, creation, deletion, or execution of actions.

RECOMMENDED RULE

The rule that runs ui_find safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude Mobile, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ui_find, this is the rule to start with:

ui_find Allowed

ui_find is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ui_find": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Claude Mobile, apply this rule, and every ui_find call is checked against it from then on.
