USBmount is a set of scripts used to automatically mount USB mass storage devices when they are plugged in. While it's not created to only run on servers, USBmount is especially useful on a server because it doesn't have a graphical user interface, and it doesn't depend on any desktop environment. And most desktops can already automount USB devices.
By default USBmount automatically mounts USB devices using
/media/usb0, /media/usb1, ..., /media/usb7 mount points, with /media/usb0 being the first plugged in USB device, /media/usb1 being the second USB device you plugged in, and so on.
