MPP handles 'how do agents pay', but not 'did anyone authorize this'. For low-value API calls that's fine. But once agents start chaining transactions, you need a channel where the agent can ask a human 'I'm about to spend $2k on this, still in scope?' before the payment happens - not a fraud alert after. The authorization layer is a separate infrastructure problem from the payment protocol.

The good ol' folks at Stripe's collaborators Tempo Labs tried to make an RFC-style description page for MPP: https://paymentauth.org/ (full doc on IETF draft page: https://datatracker.ietf.org/doc/draft-ryan-httpauth-payment... ) I almost was going to point it out as evidence there was thought put into it. Nope, it's flimsy and AI generated. Also, it contains provisions for scamming customers: > 403 indicates the pay…
I recently redesigned my blog to look like a modern RFC and I'm loving the way they've decided to render tables in their plain text, definitely gonna steal that. On topic though, Stripe is trying to make themselves the Visa/Mastercard of crypto. They're in position to do so and it seems like Coinbase is their other half. I don't trust or like it though.

This one is even worse IMO > Servers MAY return 402 when: > * Offering optional paid features or premium content This implies that a successful GET request to a resource that user already does have access to, might still return 402 instead of 200. This makes 402 basically unworkable.
An RFC is a request for comments, contributions. Are you open to contributing to this RFC?
What does this actually have to do with agents? What does the protocol include that makes this useful with AI rather than just a boring old program?
There's a slightly new topic called Agentic Commerce, where you say for example: "purchase for me the most energy efficient dishwasher with a budget of $600", and the agent will connect via specialized via special MCP Servers and APIs to available stores, and will do the full purchase process for you. This MPP helps bridge the gap between the agent putting the product "in the basket", to actually completing the full…
Okay, I am NEVER letting an agent make payment autonomously. If there's a payment that has to be made, tell me, I will do that myself.

The best Visa/Mastercard of crypto already exists and is called Flexa. ( https://flexa.co/payments#pricing )
For those of you in Brazil, my company jota.ai has built a financial AI-assistant that you can chat with to open a bank account, connect with accounts from other banks, make instant Pix payments with any of them, all of that through WhatsApp right now. We're working hard to release long-running agents soon that can do increasingly complex workflows involving payments and whatnot. Please let us know if you have sugges…
