Return whether studio mode is enabled, plus the current preview and program scenes.

Enable or disable studio mode (preview/program layout).

Overall audio status: mute/volume of all audio-capable sources.

Set how a source's audio is monitored: NONE (off), MONITOR_ONLY (hear only), or MONITOR_AND_OUTPUT (hear and broadcast).

Set an audio sync offset in milliseconds for a source. Positive delays audio, negative advances it.

Play, pause, stop, restart, or skip a media/VLC source. Actions: PLAY, PAUSE, STOP, RESTART, NEXT, PREVIOUS.

Get the current playback position and duration of a media source.

Seek a media source to a specific time in milliseconds.

Set the duration (ms) of the active scene transition.

List all filters attached to a source with their state.

Add a filter to a source, e.g. chroma_key_v3, noise_suppress_v2, gain_filter, color_filter. Optionally pass settings.

Remove a filter from a source. High-impact: requires confirmation.

Get the settings and state of one filter on a source.

Modify the settings of a filter on a source.

Enable or disable a filter on a source.

List all OBS profiles and the active one.

Switch to another OBS profile. Medium risk.

Create a new OBS profile. Medium risk.

List all OBS scene collections and the active one.

Switch to another OBS scene collection. High impact.

Create a new OBS scene collection. Medium risk.

Get whether OBS is recording, paused, and for how long.

Start recording. Medium impact: may require confirmation.

Stop the current recording and return the saved file path.

Pause the active recording.

Resume the paused recording.

Get the folder where recordings are saved.

Change the folder where recordings are saved.

Get whether the replay buffer is active or saving.

Start the replay buffer (requires it to be enabled in OBS).

Stop the replay buffer.

Save the current replay buffer to disk (the buffer keeps recording afterwards).

Get whether OBS is live, reconnecting, and stream duration.

Start the live stream. HIGH IMPACT: going live is visible to viewers, so explicit user confirmation is required.

Stop the live stream. HIGH IMPACT: ends the broadcast for all viewers, so explicit user confirmation is required.

Check stream health: dropped frames, congestion, reconnects.

Inspect the stream service type and configured settings.

Set the stream service and its settings (server URL, stream key, service name, etc.). Example: 'Set my stream key to X on rtmp://ingest.example.com/live'.
