WHAT IT DOES

What adb_input_keyevent does on Jshookmcp

AI agents invoke adb_input_keyevent to trigger actions in Jshookmcp. 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 adb_input_keyevent is rated High

Sends input events to Android device via ADB shell, triggering external device operations.

RECOMMENDED RULE

The rule that runs adb_input_keyevent safely

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

adb_input_keyevent Rate-limited

adb_input_keyevent 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.

          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

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