How do I check if a player is offline?

Use the `list_players` tool. It will return a list of all players including their current status (online/offline) and last seen timestamp.

Can I see which media files are available for broadcast?

Yes. Use the `list_medias` tool to retrieve your library, including filenames, IDs, and file types. This is perfect for auditing your content before scheduling.

Is it possible to manage users via the agent?

You can list existing users and groups using the `list_users` tool to audit permissions and access, but creating or deleting users must be done in the 4YouSee Manager.
