MX support multiple links to a switch without looping?

Because MX doesn't support LAG, so can connect two links between a MX and a switch? like switch spanning tree to block one link? Anyone please advise, thanks in advance.

@BrechtSchamp they have even udated the documentation to use the method I was recommending in that article.

@Qing , the MX will pass STP, so if you connect two links between an MS and an MX the MS will block one of the links because it sees its own BPDU.

Thanks a lot for everyone's kind reply.
