OBS Controller — OpenClaw Plugin

Control OBS Studio directly from OpenClaw chat. Switch scenes, start/stop streaming/recording, manage audio, toggle sources, save replays, trigger hotkeys — all through natural language.

⚠️ Important Safety Notice

This plugin gives your AI agent live control over OBS Studio. The tools it provides can start streams, stop recordings, change scenes during a broadcast, toggle sources, and trigger arbitrary hotkeys — all of which can immediately affect a live production.

• Use tool allowlisting — only expose obs_* tools to agents you trust with production control
• Configure confirmation rules for destructive actions (obs_start_stream, obs_stop_stream, obs_start_recording, obs_stop_recording, obs_trigger_hotkey) if you want a human in the loop
• Set a strong OBS WebSocket password — this plugin connects to your local OBS instance via WebSocket; anyone with access to that port can control your stream
• Be aware of prompt injection risk — if an agent can trigger OBS actions based on chat input, untrusted content could theoretically induce scene switches or stream state changes

These tools are powerful on purpose. Use them with the same caution you'd use for any live-production control surface.

Requirements

• OpenClaw gateway
• OBS Studio 28+ with obs-websocket enabled (Settings → WebSocket Server)

Install

clawhub install obs-controller

Then enable it in your OpenClaw config (openclaw.json):

{
  "plugins": {
    "allow": ["obs-controller"],
    "entries": {
      "obs-controller": {
        "config": {
          "host": "localhost",
          "port": 4455,
          "password": "your-obs-websocket-password"
        }
      }
    }
  }
}

If your agent's tool policy restricts tools, whitelist the obs_* tools in alsoAllow.
