# Providers

These pages document the **watch providers** used by Watcher mode.

Watch providers connect to media servers and emit normalized scrobble events.

{% tabs %}
{% tab title="End users" %}
{% hint style="info" %}
If you want setup steps, use [Watcher](/crosswatch/scrobble/watcher.md).
{% endhint %}

### Supported providers

* [Watch: PLEX](/blueprint-architecture/scrobble/providers/watch-plex.md)
* [Watch: Jellyfin](/blueprint-architecture/scrobble/providers/watch-jellyfin.md)
* [Watch: Emby](/blueprint-architecture/scrobble/providers/watch-emby.md)

### Common gotchas

* Missing external IDs means sinks may skip events.
* Filters can drop events quietly.
* Server UUID and username must match your config.

Related pages:

* Scrobble pipeline: [Scrobble](/blueprint-architecture/scrobble.md)
* Outbound sinks: [Sink](/blueprint-architecture/scrobble/sink.md)
  {% endtab %}

{% tab title="Power users" %}

### Contract

Watch providers do two things:

1. Listen to playback state changes on the server.
2. Emit `ScrobbleEvent` into the dispatcher.

The dispatcher decides what gets forwarded to sinks.

### Code map

* `providers/scrobble/plex/watch.py`
* `providers/scrobble/jellyfin/watch.py`
* `providers/scrobble/emby/watch.py`

### Config touchpoints

Most keys live under:

* `scrobble.*`
* `<provider>.*` (`plex.*`, `jellyfin.*`, `emby.*`)
* filters (server UUID and username allowlists)
