WHAT IT DOES

What get_ui does on Claude Mobile

AI agents call get_ui 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 get_ui is rated Low

This tool retrieves or inspects the current state of UI elements displayed on a mobile device screen. It has no side effects—it does not modify device state, execute commands, or trigger actions. It is purely informational, similar to taking a screenshot or querying the device's UI tree.

From the tool's definition Tool name 'get_ui' and description 'Get UI elements on screen' indicate data retrieval with no modification or execution. The verb 'Get' combined with 'UI elements' describes a query/inspection action.

RECOMMENDED RULE

The rule that runs get_ui 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 get_ui, this is the rule to start with:

get_ui Allowed

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

  "tools": {
    "get_ui": {}
  }
}

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 get_ui call is checked against it from then on.
