Stripe documents MPP as an internet-native way for agents to pay

Stripe published MPP, an open standard co-authored with Tempo, as an internet-native way for AI agents to pay for APIs, MCP servers, and HTTP resources, the company announced on 18 March 2026. Under MPP, an agent requests a resource, the service returns a payment request, the agent authorizes it, and Stripe businesses see the payment as they would any other PaymentIntent. Stripe also stated payment support for both MPP and x402 within a broader agentic commerce stack, which zFinia characterized as evidence the machine-buyer market is multi-rail and will require routing rather than a single protocol.

Stripe acknowledging both MPP and x402 is evidence the market is multi-rail. Machine buyers will need routing, not a single-protocol religion.
