Stripe’s Machine Payments Protocol (MPP), introduced by the payments company earlier this month, could revive micropayments by enabling AI agents to execute transactions automatically, according to analysis from Forrester.
That’s the key takeaway from a newly published analysis by Forrester senior analyst Meng Liu, who argues that MPP may succeed where decades of earlier efforts failed.
MPP enables AI agents to execute transactions automatically, removing the need for human approval at each step. It is described as an open protocol for coordinating payments between AI agents and services. Liu frames this as a structural shift from human-initiated payments to machine-to-machine transactions.
Micropayments — small transactions worth a few cents or dollars — have long been seen as a way to monetize digital content, services and data, but have struggled to gain traction at scale.
A major barrier to adoption has been human behavior, including cumbersome digital checkout processes and reluctance to approve small charges, Liu said.
By contrast, AI agents can execute payments as part of task completion — such as paying for data or services — removing these constraints.
“Payment becomes a programmatic step, not a discrete decision,” Liu wrote. “There’s no checkout moment, no cart abandonment risk, and no mental transaction cost.”
MPP is not a new settlement network. Instead, it acts as a coordination layer for automated payments, designed to work across existing infrastructure, including traditional rails, digital wallets and, where supported, crypto rails.

AI payments push extends beyond Stripe
Stripe has expanded into digital assets, including support for stablecoins and crypto on-ramps, though MPP itself is not blockchain-based.
Other companies are also building infrastructure for AI-driven payments. MoonPay, for example, released an open-source wallet standard that allows AI agents to hold and transact digital assets without human intervention.
Bernstein analysts said AI agents could boost demand for stablecoins, which are well-suited to frequent, low-value payments. They also pointed to Coinbase’s x402 protocol, which enables automatic internet payments between machines.
