We compute four point functions of the stress tensor and conserved currentsin AdS_4/CFT_3 using bulk perturbation theory. We work at treel level in thebulk theory, which we take to be either pure gravity or Yang Mills theory inAdS. We bypass the tedious evaluation of Witten diagrams using recentlydeveloped recursion relations for these correlators. In this approach, the fourpoint function is obtained as the sum of residues of a rational function ateasily identifiable poles. We write down an explicit formula for the four pointcorrelator with arbitrary external helicities and momenta. We verify that,precisely as conjectured in a companion paper, the Maximally Helicity Violating(MHV) amplitude of gravitons or gluons appears as the coefficient of aspecified singularity in the MHV stress-tensor or current correlator. Wecomment on the remarkably simple analytic structure of our answers in momentumspace.
