MMT is Kenysianism, with a fresh coat of paint and slightly different policy. (I say this as Keynsian.)

MMT advocates the government directly printing money for stimulus, instead of going through the charade of creating debt and letting banks print money for themselves, and gets a little wacky by hinting that you can print money without inflation.

Fiat currency debt is just printing money. The nation isn't borrowing sheep or wood, the banks just increase some numbers in a digital file ("fractional reserve" banking, where someone else gets to spend money that is in your account at the bank)
