  We present the results of a weekly monitoring of the new black hole candidate
X-ray binary MAXI J1631-472 carried out with the MeerKAT radio interferometer,
the Neil Gehrels Swift Observatory, and the Monitor of All-sky X-ray Image
(MAXI) instrument, during its 2018-2019 outburst. The source exhibits a number
of X-ray states, in particular both high- and low-luminosity hard states
bracketed by extended soft states. Radio flaring is observed shortly after a
transition from hard/intermediate states to the soft state. This is broadly in
agreement with existing empirical models, but its extended duration hints at
multiple unresolved flares and/or jet-ISM interactions. In the hard state
radio:X-ray plane, the source is revealed to be 'radio quiet' at high
luminosities, but to rejoin the `standard' track at lower luminosities, an
increasingly commonly-observed pattern of behaviour.
