This is a good standard that I can get behind [0] since it's a serious proposal and submitted to the IETF [1] for MPP for machine-to-machine payments.

A well thought out proposal for the long term, unlike MCP which is a complete joke of a "standard" and broken by design.

Curious since I haven't followed super closely: what's busted about MCP?
