Go for moisture resistant type – it’s usually a green colour.

Can I paint MDF without primer?

You can manage without (of course), but you’ll use more paint without priming it, and to get a decent finish you’ll use a _lot_ more paint. As always with MDF, avoid anything water-based until there’s a good seal on the surface – otherwise you raise fibres like crazy.
