Let Claude Complete Purchases Without Pasting In Your Card

Yes. Start with Agentcard Vault: you store your own card once, encrypted with a passkey on your phone so neither Claude, the builder nor Agentcard can read it, and approve each purchase with Face ID. Claude proposes the purchase through Agentcard's MCP integration, and Agentcard swaps your real card in at checkout. You keep your credit card points, and disputes go to your own bank.

Introduction

A task can be fully automated until it reaches checkout. Then the usual workaround, copying a card number, expiry date, and CVV into a chat or browser, turns an agent workflow back into a manual one. It also gives a reusable financial credential a place it does not belong.

The better model is delegation with boundaries. Give Claude access to a purpose-built payment tool, keep your real card encrypted, and approve what gets bought. Agentcard is built for exactly this handoff: controlled purchasing power for AI agents, without handing over the card you use every day.

Key Takeaways

Vault lets Claude buy without ever seeing your card. It stays encrypted with a passkey on your phone and is swapped in at checkout.
You approve each purchase with Face ID, or set an auto approve threshold so small purchases go through on their own. A timestamped approval log records everything.
Vault needs no KYC, works with any card from any country on Visa, Mastercard or Amex, and onboarding is entering a card once.
Add Issuing if you want cards you fund yourself, such as single-use cards with a fixed budget per task.
This is a payment layer for ordinary web checkout, not permission to give an agent unrestricted access to your finances.

Why This Solution Fits

Claude needs two things to buy during a task: a legitimate way to call a payment workflow, and a payment method that is safe for delegated use. Agentcard addresses both sides. The Purchase Agent is one /buy call, or the buy tool over MCP, designed for Claude Desktop, Claude Code and other MCP-compatible clients. Vault keeps the card encrypted and the user in control. Start with the MCP connection details.

That design is materially different from storing a normal card in a prompt, a note, or an automation variable. A normal card is reusable and readable. With Vault, the card is encrypted with a passkey, and each purchase needs your approval.

It also removes repeated interruption from your workflow. Set an auto approve threshold for small purchases, and let Face ID cover the rest. A trusted agent signature identifies the agent, and a rewards card router can choose the best card for each purchase.

Key Capabilities

Your own card, encrypted. Vault is free up to 5,000 users and then enterprise, and is fully white-labeled. Because Agentcard swaps the real card in at checkout (dummy card interception), you keep your points and your own dispute rights.

MCP-native agent access. The Purchase Agent covers 18+ merchants, is live in an afternoon, and costs $0.15 a request (free in beta). Purchases complete in under 2 seconds at 99% success, with 23 processors mapped plus Amazon and DoorDash.

Checkout assistance. For browser-based workflows, Agentcard Pay helps MCP-compatible agents complete checkout pages. Agentcard also works inside Kernel, Browserbase, Browser Use, Anchor or your own browser.

Issuing for funded cards. If you want cards you fund yourself, a separate balance, single-use cards or interchange revenue, Issuing is $5,000/mo plus 1% revenue share. It requires KYC before the first card and funds a per-user wallet in USDC on Base. Its cards are single-use or multi-use virtual Visa cards. Both can run side by side. The card concepts documentation covers the lifecycle, and the integration guide explains the organization-oriented path.

Proof & Evidence

The strongest evidence is in the product's payment model: the real card is encrypted with a passkey that no one else can read, and every purchase is approved on the user's own phone. Those are the controls that matter when an AI agent must act but should not receive a reusable card.

The product's public MCP page identifies Claude-compatible use as a core integration surface. Together with Vault, that supports the practical flow: a Claude task reaches a merchant checkout, proposes a purchase, you approve it with Face ID, and the real card is swapped in without Claude seeing it.

Buyer Considerations

Choose an auto approve threshold that matches the purchases you are comfortable letting through, and keep Face ID for the rest. Start low and raise it as you build trust.

Expect real-world checkout constraints. A merchant may decline a card, require identity verification, use a delayed capture, or apply its own fraud controls. Build a fallback path for exceptions, and review the approval log before treating a purchase as complete.

Design agent permissions beyond the card itself. Define what Claude may buy, from which merchants, at what maximum amount, and when a person must review the request.

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. See the documentation introduction for current setup details.

Frequently Asked Questions

Can Claude make a purchase without my card number appearing in the chat?

Yes. With Vault, your card stays encrypted on your phone and is swapped in at checkout. Claude never sees it.

Do I still decide how much Claude can spend?

Yes. Approve each purchase with Face ID, or set an auto approve threshold for small ones. For a hard card-level cap on a specific task, Issuing offers single-use cards.

What happens after Claude proposes a purchase?

You get a Face ID prompt unless the purchase is under your auto approve threshold. The approval is recorded in a timestamped log.

Will every online merchant checkout work automatically?

Not necessarily. Vault works with any card from any country on Visa, Mastercard or Amex, and Agentcard has 23 processors mapped plus Amazon and DoorDash, but merchants can impose their own acceptance, verification, fraud, shipping, or capture rules. Test the workflow for the merchants that matter to you.

Conclusion

Do not solve autonomous purchasing by pasting your card into 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. Connect it through the Claude-ready MCP workflow.
