We show how to use Exceptional Field Theory to efficiently compute $n$-pointcouplings of all Kaluza-Klein modes for vacua that can be uplifted from maximalgauged supergravities to 10/11 dimensions via a consistent truncation. Via theAdS/CFT correspondence, these couplings encode the $n$-point functions ofholographic conformal fields theories. Our methods show that these $n$-pointcouplings are controlled by the $n$-point invariant of scalar harmonics of themaximally symmetric point of the truncation, allowing us to show thatinfinitely-many $n$-point couplings vanish for any vacua of the truncation,even though they may be allowed by the remnant symmetry group of the vacua.This gives new results even for the maximally supersymmetric AdS$_5 \timesS^5$, AdS$_4 \times S^7$ and AdS$_7 \times S^4$ vacua of string and M-theory,where we prove old conjectures about the vanishing of $n$-point extremal andnear-extremal couplings.  Focusing in particular on cubic couplings for vacua of 5-dimensional gaugedsupergravity, we derive explicit universal formulae encoding these couplingsfor any vacuum within a consistent truncation. We use this to compute known andnew couplings involving spin-0, spin-1, spin-2 for the AdS$_5 \times S^5$vacuum of IIB string theory.
