Abstract
In this letter we provide a complete holographic reconstruction of the cubic couplings in the minimal bosonic higher-spin theory in AdS. For this purpose we also determine the OPE coefficients of all single-trace conserved currents in the -dimensional free scalar vector model, and compute the tree-level three-point Witten diagram amplitudes for a generic cubic interaction of higher-spin gauge fields in the metric-like formulation.
