Machine Payments Protocol

Introducing the Machine Payments Protocol: an open standard for machine payments co-authored by @tempo and @stripe MPP is designed to be extensible and payment-method agnostic, already supporting stablecoins, cards, and more.

Worth watching. Preview of the future.

I paid for several premium financial newsletters and built a chat interface on top of them. Writers get paid each time their posts are used in an answer via @mpp on @tempo and x402 on @base. Check it out: dripstack.xyz

At Stripe Sessions, we showed how we think agentic commerce will often happen behind the scenes in the course of producing other final products. Here, we show our Claude Code using MPP and @tempo to buy a dataset from @alpha_vantage in the process of generating a research report for me on AI energy usage.

Today at Sessions, @collision showed an agent acting as both buyer and seller in the same loop. Using Stripe Projects and Tempo Wallet, the agent: • Paid $0.04 for an Alpha Vantage dataset in stablecoins • Generated a research report • Listed it for sale to humans and agents

A smattering of what people are already building with @mpp. 🧵

MPP in Visa earnings call! It is going to be incredible to see every CLI integrate MPP to make it frictionless for their agents to pay on the web. The @wevm_dev team recently put out Incur, an amazing new library for building agentic CLIs. You should try it out. github.com/wevm/incur

Already supported in the mppx SDK. Configure multiple methods in discovery() and the offers array populates automatically. Docs: mpp.dev/advanced/disco…

MPP discovery now supports multiple payment offers in a single document. Services can declare every payment method, currency, and intent type they accept ahead of time. Registries get the full pricing surface in one fetch. Full blog post below.

We just recorded the first fully autonomous agent wine purchase. @agentscoredev enabled the policies including KYC to verify 21+ to purchase wine from @martinestate. The agent handled the rest — payment over @Tempo USDC, @MPP + @stripe rails, order confirmed. Agentscore is the trust layer for agentic commerce - identity, compliance, and risk, so agents can transact autonomously.

isitagentready.com now checks if your site supports @mpp (Machine Payments Protocol)

Agentic Restaurant Reservations. If your agent has a wallet and supports x402/@mpp via @agentcashdev, @coinbase, or @tempo, it can now book restaurant reservations through agentres.dev Built this as a fun experiment. Give it a try!

The MPP Ruby SDK is maintained by @stripe GitHub: github.com/stripe/mpp-rb

MPP now has official SDKs for Go and Ruby. Both implement the full MPP flow: core types, payment methods, server middleware, and client transports. Full blog post below.

AI agents can now register domains and pay for them with zero human involvement using @mpp, @tempo's & @stripe's new protocol for machine-to-machine payments. 👉mpp.dev Our team built this demo at the @tempo hackathon. It's live. It works. And it's a preview of an entirely new category. Here's what we built and why it matters 🧵

Cool to see Cloudflare working with @mpp!

Cool use of MPP!
