This link leads to five cases illustrating the use of MCS for a selection of of RASFC scenarios. The cases are discussed in two papers at these links:

Diagnosing open-system magmatic processes using the Magma Chamber Simulator (MCS): part I—major elements and phase equilibria

Diagnosing open-system magmatic processes using the Magma Chamber Simulator (MCS): part II—trace elements and isotopes

PDF ‘s of these papers as well as all MCS files corresponding to the cases  discussed in the papers may be found here and here.

The MCS files for the cases discussed in the papers are here.

An addition study that used the MCS model is: 

From binary mixing to Magma Chamber Simulator - Geochemical modeling of assimiliation in magmatic systems

This publication is available at https://www.essoar.org/doi/10.1002/essoar.10504606.2 or here.

A recent study that used MCS results extensively to study Granitoids from the Lachlan Fold Belt may be found here:
