We compute the modification of the ₁₊∞ algebra of soft graviton, gluon, and scalar currents in the celestial CFT due to non-minimal couplings. We find that the Jacobi identity is satisfied only when the spectrum and couplings of the theory obey certain constraints. We comment on the similarities and...
