Lidarr

Lidarr integration enables lifecycle actions on music managed by Lidarr.

Setup

1. Go to Settings → Integrations
2. Under the Lidarr section, click Add Instance
3. Enter:
   • Name: A label for this instance (e.g., “Main Lidarr”)
   • URL: Lidarr’s base URL (e.g., http://192.168.1.100:8686)
   • API Key: Found in Lidarr → Settings → General → API Key
4. Click Test Connection to verify
5. Save

You can add multiple Lidarr instances.

How Matching Works

Librariarr matches music to Lidarr using MusicBrainz IDs:

1. During media sync, external IDs are fetched from your media server
2. When lifecycle rules need Lidarr data, Librariarr queries Lidarr by MusicBrainz artist ID
3. Fallback: artist name matching

Available Operations

Once connected, these operations are available via lifecycle rules:

Operation	Description
Delete	Remove the artist/album from Lidarr (optionally delete files)
Unmonitor	Stop Lidarr from monitoring for upgrades
Tag	Add a custom tag to the artist in Lidarr

Data from Lidarr

The following Lidarr metadata is available for lifecycle rule conditions:

• Quality profile: The assigned quality profile name
• Monitored status: Whether the artist is monitored
• Tags: Current tags on the artist

Security

• API keys are stored securely and never sent to the frontend
• Connection testing uses server-side endpoints
• All integration responses are sanitized

Limitations

• MusicBrainz ID availability depends on your media server’s metadata agent
• Lifecycle actions require Lidarr to be reachable at execution time
• Music matching can be less reliable than movie/series matching due to artist name variations
