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, add cash, create cards, and shop.How it works
- Sign in —
agent-cards signup(or connect the MCP server) and approve the sign-in in your browser; we fall back to an emailed one-time code where a browser isn’t available. - Add cash to your balance — Add money with Apple Pay or Google Pay via a secure checkout link. Your cash balance funds the virtual cards you create.
- Create a card — Issue a virtual Visa with a spend limit. It draws on your cash balance when the card is used.
- Give it to your agent — Your agent uses the card number, expiry, and CVV to check out.
- Monitor and close — Track balances in real time and close cards when done to return unspent funds to your balance.
Key features
- Fixed-limit cards — Each card is backed by your cash balance with a fixed cap, so your agent can never overspend.
- Per-card limits — Every card has a fixed spend limit (up to 500 on Basic, $1,000 on Pro — see Plans).
- Live by default — Cards are real and draw on your cash balance. A card marked TEST comes from a connection that isn’t live, usually a company’s test-mode integration (Test cards).
- Shop in natural language — The
buysurface lets your agent order from linked merchants end-to-end. - Safe by design — Card numbers are never shown unless you ask; closing a card is always confirmed.
