As far as I know there was a package called Phi http://www.feyncalc.org/phi/.
I am not aware of the status of this package but it allowed to obtain
couplings right from the lagrangians for some theories and was available in
FeynArts/FeynCalc. There is FeynRules package
http://feynrules.irmp.ucl.ac.be/ for doing that but I did not use it.
