Most MDF these days should have moisture resistant glue to some extent. If you seal it all round (as I would suggest for timber also) it should be fine. MDF is used for so much it's not funny. Here in Australia and I imagine in USA, it is used for cabinets and kickers ( in wet areas ), kitchens, mouldings, trims, base boards ( in bathrooms as well ) dados, door frames, doors and I'm sure more. I've used it in wet areas, I've used it every where. I even used it to replace glass in a 3 x 3 window and it was facing the sun all day long with only a bit of spouting overhand to protect from the elements. After 4 years it looked like it was ready to be replaced.
Yes I have used it as a mantle. Have only seen problems when used to replace glass in a window or where there has been very poor protection from excessive water.
