Optical nonreciprocity plays a significant role in quantum optics domain-underpinning a myriad of phenomena and applications. In this paper, we propose a feasible scheme to analyze the nonreciprocal optical bistability and nonreciprocal transmission in a hybrid atom-optomechanical system. We find that the nonreciprocal optical bistability behaviors can be enhanced and promoted when the atom-cavity interaction is introduced. In particular, the cavity-atom interaction also makes the photon transmission more sensitive to the propagation direction enabling the nonreciprocal transmission with the low input field intensity in a weak optomechanical coupling regime. Implementation of such scheme will demonstrate some mechanisms of optical nonreciprocity and may be beneficial for generation of the nonreciprocal optical devices.
