WHAT IT DOES

What hotkey does on Agent Browser

AI agents invoke hotkey to trigger actions in Agent Browser. 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 hotkey is rated High

Sending hotkey chords constitutes physical keyboard input that can trigger arbitrary browser or OS-level actions (e.g., Ctrl+W to close tabs, Ctrl+S to save, Alt+F4, etc.). Since this operates on a real browser with live sessions and cookies, misuse could trigger significant unintended operations. The description is minimal but the server context clarifies it controls a real browser with full privileges.

From the tool's definition 'Send a hotkey chord' — triggers keyboard input actions in a real Chrome browser with full session context including login sessions and cookies

RECOMMENDED RULE

The rule that runs hotkey safely

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

hotkey Rate-limited

hotkey 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.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "hotkey": {
      "limits": [
        {
          "counter": "hotkey_rate",
          "window": "minute",
          "max": 10,

        }
      ]
    }
  }
}

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

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