We examine Nica-Pimsner algebras associated with semigroup actions of$\mathbb{Z}_+^n$ on a C*-algebra $A$ by $*$-endomorphisms. We give necessaryand sufficient conditions on the dynamics for exactness and nuclearity of theNica-Pimsner algebras. Furthermore we parameterize the KMS states at finitetemperature by the tracial states on $A$. A parametrization is also shown forKMS states at zero temperature (resp. ground states) by the tracial states on$A$ (resp. states on $A$). Finally we give a formula for obtaining tracialstates on the Nica-Pimsner algebras.
