Mastercard and Alchemy are preparing a service that would let an AI agent buy things on a person’s behalf, using payment limits set in advance. The product, called AgentCard, is aimed at bounded autonomy: a cardholder could specify rules such as a price range, then let software order food, book travel, or shop without approving every checkout. Alchemy says developers can provision each agent with a dedicated email address, phone number, stablecoin wallet, and one-time Mastercard payment credentials through a single command-line setup that takes less than a minute. The harder problem is authorization. Mastercard’s chief AI and data officer, Greg Ulrich, says the company’s existing fraud systems were built to stop bots from transacting. Those controls are useful when automation is suspicious, but they could also block an agent that a customer has explicitly authorized. So the partnership depends on new ways for merchants and payment networks to verify that an agent is trusted, and to connect its transaction to the limits set by its owner. Mastercard, Visa, and Ant International have separately discussed common standards for identifying trusted agents in online purchases. Alchemy already has a Visa partnership, according to Gizmodo, so Mastercard would add another conventional card route alongside the wallet. The service is still being prepared, with no launch date announced. The key constraint is whether payment systems can permit bounded automation without weakening the protections designed to stop unauthorized bots.

    AgentCard is designed for bounded autonomy: users define purchasing parameters before an agent orders food, books travel, or shops.

    Alchemy says developers can provision an agent’s email, phone, wallet, and payment credentials in under a minute through one CLI.

    Mastercard chief AI and data officer Greg Ulrich said existing anti-fraud rules were built to stop bots from transacting.

Mastercard and Alchemy are preparing a payment option that would let cardholders authorize AI agents to make purchases inside preset limits. The promise is convenient delegated shopping; the constraint is that Mastercard says its anti-fraud rules were built to stop bots from transacting.

The intended use is more than an assistant recommending a product. Cardholders could let an agent independently order food or book travel after setting parameters such as a price range, rather than approving every checkout individually.

Alchemy says AgentCard packages the elements an automated buyer needs to operate online: a dedicated email address, phone number, stablecoin wallet and one-time-use Mastercard payment credentials. The company says developers can set up that package for an agent through one command-line interface in under a minute.

That boundary does not remove the central payments problem: proving that the software presenting itself at checkout is authorized. Mastercard chief AI and data officer Greg Ulrich said the company has accumulated risk rules meant to prevent bots from making transactions, and enabling agents requires a change to that framework.

The issue extends beyond this partnership. Mastercard, Visa and Ant International previously said they were working on common standards to verify trusted AI agents in online purchases. Shared verification could help merchants and payment networks recognize an agent, while each transaction still depends on the limits its cardholder set.

Alchemy already has a Visa partnership, according to Gizmodo. Adding Mastercard would give AgentCard another route into conventional card checkout alongside its stablecoin wallet, instead of making agent payments dependent on one card network.

The planned service makes the trade-off plain. It removes repeated human approval from routine purchases, but asks payment systems to accommodate automated activity without losing the protections that made unexpected automation suspicious in the first place.
