  We revisit the relation between black hole geometries and chiral transport.
Integrating the anomaly equation in a black hole geometry allows to derive the
chiral transport coefficients for the thermal gas far from the horizon. The key
ingredient is to impose vanishing of the covariant current on the horizon. We
extend the method to include the usual gauge anomaly for charged black holes
and to weak magnetic fields. This allows to derive the full set of transport
coefficients describing the chiral magnetic and chiral vortical effects.
