We present the tree-level five-point amplitude of the lowest Kaluza-Klein mode of super-Yang-Mills theory on ${\mathrm{AdS}}_5\times S^3$, dual to the correlator of the flavor current multiplet in the dual $4d$ $N=2$ superconformal field theory. Its color and kinematical structure is particularly simple and resembles that of the flat-space gluon amplitude.
