How do I perform a remote unlock using the agent?

Use the `unlock_door` tool with the unique ID of the lock you wish to open. Make sure the authenticated user has the necessary permissions for that door.

Can I see if a door is currently online?

Yes, the `list_locks` and `get_lock_details` tools return the real-time connectivity status (online/offline) for every device.

Is it possible to list all users in my organization?

Absolutely. Use the `list_users` tool to retrieve a comprehensive list of all members registered in your Kisi organization.
