You should try doing a search of the forums first before asking this, since it's been asked what seems like a million times. But here's what Jim had to say about it recently.

MQA -- Solution in pursuit of a problem.
I happen to share Jim's opinion of MQA and personally find it to be pointless (not to mention it's not actually lossless contrary to the claims that it is). So while official support is likely not going to happen, you
can however passthrough MQA to your MQA-supporting DAC through MC by a) not using any DSP whatsoever (no output format, volume leveling, adaptive volume, etc.) and b) having both internal volume in MC along with system volume set to 100%. I've been told that does work, but I wouldn't be surprised if it doesn't.
