I don't think you are doing anything wrong. It rather looks like the 
version you use is and old version of v.lidar.mcc. The parameters of 
g.remove have changed in grass 7 and v.lidar.mcc does not use a call 
such as "grass.run_command('g.remove', vect = '%s,%s,%s'" anymore.

Try reinstalling v.lidar.mcc using g.extension.
