Is there any materialX node to get a radial or circular ramp? If not how could I go about making one?

One way is to use the attributepaint node. Click once in the center to generate a faded radial mask attribute. Then you can use that mask to drive a ramp in the color node. Feed that Cd or mask into the MTLX shader to drive what ever parameter you want.
