This doesn’t appear to be wrapped at the MathProgBase level in Gurobi.jl, but following the example of cbgetmipsolution (Gurobi.jl/MPBWrapper.jl at 120d606da08facffb206d73d932dbb0bf7d7001d · jump-dev/Gurobi.jl · GitHub) you could write a similar wrapper that calls Gurobi.cbget_mip_cutcnt. I don’t have a Gurobi license so I can’t test this.
