  The possibility of the strong electron-electron interaction driven insulating
phase from the metallic phase in two-dimensions has been suggested for clean
systems without intentional disorder, but its rigorous demonstration is still
lacking. Here, we examine the finite-temperature transport behavior of a few
layered-MoS$_2$ material in the vicinity of the density-driven metal-insulator
transition (MIT), revealing previously overlooked universal features
characteristic of strongly correlated electron systems. Our scaling analysis,
based on the Wigner-Mott theoretical viewpoint, conclusively demonstrates that
the transition is driven by strong electron-electron interactions and not
disorder, in striking resemblance to what is seen in other Mott systems. Our
results provide compelling evidence that transition-metal dichalcogenides
provide an ideal testing ground for the study of strong correlation physics,
which should open an exciting avenue for future research, making a parallel
with recent advances in twisted bilayer graphene
