"Protein folding" and "lattice model" are almost mutually contradictory.
Once you reduce yourself to a lattice model, you are no longer doing
anything very protein-like.  Some biophysics people have used lattice
models to see what happens in simplified systems, since real proteins
are too complex, but their results can hardly be called protein folding.

A Monte Carlo algorithm is simply one in which randomness plays a
major role.  There is no single "Monte Carlo" algorithm.

I don't know of any free Monte Carlo web services for proteins, as
Monte Carlo simulation is, by its very nature, rather compute
intensive.
