How do I get my Plex Token?

Log in to your Plex account at [**plex.tv**](https://plex.tv), go to **Settings > Server > General** and look for 'X-Plex-Token'. Alternatively, check your browser's network tab when loading the Plex web app.

What is my Server URL?

For local access: `http://YOUR_SERVER_IP:32400` (e.g. `http://192.168.1.100:32400`). For remote access: `https://YOUR_PLEX_SUBDOMAIN.plex.direct:32400`. The IP is your Plex server's local network address.

Can I see what's currently playing?

Yes! Use get_sessions to see all active playback sessions. Each session shows the user, media title, playback position, player device and whether it's direct playing or transcoding.

Can I search for specific media?

Yes! Use search_library with any title. Results include movies, TV shows, episodes, artists and albums matching your query. Optionally filter by library key to search in a specific library only.
