Abstract
Package FeynGrav which provides a framework to deal with Feynman rules for gravity within FeynCalc is presented. We present a framework to deal with the corresponding Feynman rules for general relativity and non-supersymmetric matter minimally coupled to gravity. Applicability of the package is tested with 2 -> 2 on-shell tree level graviton scattering, polarization operators, and one-loop scalar-gravitational interaction structure.
