obs-trigger-hotkey-by-name

THE RISK

High Risk

This tool invokes external operations (hotkey triggers) whose effects are determined by how the hotkey is configured in OBS Studio. A malicious agent could trigger hotkeys that start/stop streaming, switch scenes, execute vendor requests, or perform other consequential actions. While not directly destructive or financial, it executes arbitrary pre-configured logic and thus falls under Execute.

From the tool's definition Tool description states it 'Triggers a hotkey using its name' — this actively executes a predefined action/command in OBS Studio.

Documented attack patterns abuse exactly the kind of access obs-trigger-hotkey-by-name gives an agent:

HOW TO CONTROL OBS-TRIGGER-HOTKEY-BY-NAME

PolicyLayer is an MCP gateway — it sits between your AI agents and OBS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for obs-trigger-hotkey-by-name:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "obs-trigger-hotkey-by-name": {
      "limits": [
        {
          "counter": "obs-trigger-hotkey-by-name_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

obs-trigger-hotkey-by-name 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.

Create a free account and register OBS MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
