  MCG-5-23-16 is a Seyfert 1.9 galaxy at redshift z=0.00849. We analyse here
the X-ray spectra obtained with XMM-Newton and NuSTAR data, which are the first
contemporaneous observations with these two X-ray telescopes. Two reflection
features, producing a narrow core and a broad component of the Fe K$\alpha$,
are clearly detected in the data. The analysis of the broad iron line shows
evidence of a truncated disc with inner radius $R_{\rm in}=40^{+23}_{-16}$
$R_g$ and an inclination of $41^{+9}_{-10}$ $^\circ$. The high quality of the
NuSTAR observations allows us to measure a high energy cut-off at $E_{\rm
cut}=131^{+10}_{-9}$ keV. We also analyse the RGS spectrum, finding that the
soft X-ray emission is produced by two photoionised plasma emission regions,
with different ionisation parameters and similar column densities. Remarkably,
the source only shows moderate continuum flux variability, keeping the spectral
shape roughly constant in a time scale of $\sim20$ years.
