WHAT IT DOES

What input_double_tap does on Claude Mobile

AI agents invoke input_double_tap to trigger actions in Claude Mobile. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why input_double_tap is rated High

This tool performs a UI interaction (double tap) on a mobile device, triggering external operations whose effects depend on arguments. A double tap can activate arbitrary UI elements, confirm dialogs, open items, or trigger app-specific actions.

RECOMMENDED RULE

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

input_double_tap Rate-limited

input_double_tap stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
