  In extended phase space, a static black hole in massive gravity is studied as
a holographic heat engine. In the massive gravity theory considered, the
graviton gain a mass due to Lorentz symmetry breaking. Exact efficiency formula
is obtained for a rectangle engine cycle for the black hole considered. The
efficiency is computed by varying two parameters in the theory, the scalar
charge Q and $\lambda$. The efficiency is compared with the Carnot efficiency
for the heat engine. It is observed that when Q and $\lambda$ are increased
that the efficiency for the rectangle cycle increases. When compared to the
Schwarzschild AdS black hole, the efficiency for the rectangle cycle is larger
for the Massive gravity black hole.
