evalin(symengine, 'numlib::sqrtmodp(132132,3231227)')
still works, as does using the command
mupad
to start a graphical interface to mupad and then entering
numlib::sqrtmodp(132132,3231227)
there.

feval(symengine, 'numlib::sqrtmodp', sym('132132'), sym('3231227'))
If our values fit within doubles, up to flintmax(), then you do not need the sym() with the quoted number:
feval(symengine, 'numlib::sqrtmodp', 132132, 3231227)
