AgentCard Personal lets an individual create and manage prepaid virtual Visa cards that their AI agent can use to make purchases on the web. You sign in with your email, save a payment method, and issue cards with a fixed spend limit — funded by a hold on your payment method and only charged when the card is actually used. This is the Personal product, built for one person managing their own cards. If you’re a company issuing cards to your end-users programmatically, see the Companies docs instead.

​
Two ways to use it

MCP server

Connect mcp.agentcard.sh/mcp to Claude Code, Cursor, Claude Desktop, or any MCP client. Your agent gets tools to create cards, check balances, and pay for things — authenticated with your own OAuth login.

CLI

Manage everything from your terminal with the agent-cards CLI — sign up, save a payment method, create cards, and shop.

​
How it works

  1. Sign in — agent-cards signup (or connect the MCP server) and click the magic link in your email.
  2. Save a payment method — Add a card via secure Stripe checkout. It funds the virtual cards you create.
  3. Create a card — Issue a virtual Visa with a spend limit. Your payment method is only charged when the card is used.
  4. Give it to your agent — Your agent uses the card number, expiry, and CVV to check out, or fills it automatically with the Chrome extension.
  5. Monitor and close — Track balances in real time and close cards when done to release held funds.

Key features

  • Prepaid cards — Each card is backed by a hold on your payment method, so your agent can never overspend.
  • Per-card limits — Every card has a fixed spend limit (up to 50onFree,50 on Free, 500 on Basic, $1,000 on Pro — see Plans).
  • Test mode by default — New accounts start in test mode and issue sandbox cards with no real charges. Switch to prod when you’re ready (Test mode).
  • Shop in natural language — The buy surface lets your agent order from linked merchants end-to-end.
  • Checkout autofill — The Chrome extension fills cards into checkout forms automatically.
  • Safe by design — Card numbers are never shown unless you ask; closing a card is always confirmed.
