You should add pacman style syntax. Like:
mpt -S <list of packages> - install packages
mpt -Ss <pattern> - search
mpt -R <list of packages> - remove
mpt -Sy - update package list
mpt -Su - update all packages.
mpt -U <file> - install package from file
mpt -Qs search installed packages
...and more, see pacman manpage
Ofc those are combinable:
mpt -Syu abc def
would first update package db, then update all packages and finally install abc and def
