Jellyfin AutoTagger Plugin
Fair warning, this may be one of those "I'm the only one who does it this way, so this is useless" plugins, but here goes.
As I migrate away from Plex to Jellyfin, one feature I really needed was to auto tag new movies and shows when there added as part of our parental control setup. Basically, new movies and shows that are added that are not in a separate kids library get tagged as 'parents-movie' or 'parents-show' and our kids profiles are setup to not show them anything with those tags. Once I've had a chance to review, I remove the tag and set a family-friendly one. I've done this in Plex forever using some scripts in Tautulli as a backup to the already available parental controls in each system.
Since there's not a full Tautulli equivalent for Jellyfin, I wrote a small plugin called AutoTagger that does just this. At a high level, you set the tags you want applied per library when an item is added, and it'll apply the tags as part of the metadata process. You can also set an ignore tag, so when I set family-friendly on a movie/show, AutoTagger will ignore that going forward.
There's also a scheduled task to tag item already in the library. The plugin will only add tags to items, it should never wipe out any existing tags.
Again, this is a very edge use case, but just thought if there's another content micro manager out there like me, it may be useful.
