Morphology
The meaning is partially derivable: 'tap' (a source or outlet, or to draw from a supply) plus 'on' (indicating active/available) suggests something is currently available, so learners familiar with those senses can often infer availability. However, the extended, idiomatic use (from a physical tap to general readiness) is not fully predictable for an average B1 learner, so it is only partially transparent.
Etymology
On tap comes from pubs and kitchens where beer or water is kept connected to a tap so it can be poured straight away. So it means 'available to be served'.
