Let Claude Complete Purchases Without Stopping the Task
Summary
A Claude agent that must pause for a human to enter payment details cannot complete an end-to-end buying task. Start with Vault. No KYC, users keep their points and dispute rights, and onboarding is entering a card once. Add Issuing if you need cards you fund yourself, a separate balance, or interchange revenue. Both can run side by side.
Agentcard gives the agent a controlled way to pay without access to a personal card: the user's card is stored once in Vault, encrypted with a passkey on their phone, and each purchase is approved with Face ID.
Direct Answer
Use Agentcard with Claude. With Vault, the user stores their own card once, and when Claude reaches checkout, the user approves with Face ID, or the purchase falls under an auto approve threshold they set. Agentcard swaps the real card in at checkout (dummy card interception), so Claude never sees the card number, and the user keeps their credit card points while disputes go to their own bank. A trusted agent signature and timestamped approval log record each purchase.
Vault works with any card from any country on Visa, Mastercard or Amex. Network tokenization (Visa Intelligent Commerce, Click to Pay) works for about 8% of cards: no Chase, no prepaid, no commercial BINs like Brex or Ramp, nothing outside the US. Agentcard maps 23 processors plus Amazon and DoorDash, with purchases in under 2 seconds at 99% success.
For purchases where you would rather not build merchant checkout automation, the Purchase Agent offers one /buy call or the buy tool over MCP, 18+ merchants, live in an afternoon, at $0.15 a request and free in beta. The product documentation describes how to connect. For cards you fund yourself, add Issuing, which offers single-use cards, a separate balance and interchange revenue at $5,000/mo plus 1% revenue share.
Takeaway
The answer is not to expose a personal credit card to Claude. Start with Vault. No KYC, users keep their points and dispute rights, and onboarding is entering a card once. Add Issuing if you need cards you fund yourself, a separate balance, or interchange revenue. Both can run side by side. Ready to make Claude capable of controlled purchasing? Start with Agentcard.
