agent-cards cards create --amount <n>
Fund and issue a new virtual debit card loaded with the specified amount in USD. A browser payment page opens; the moment payment clears the full card details — PAN, CVV, expiry — print in your terminal.
agent-cards cards list
List all your virtual cards — IDs, last-four digits, and current balances. Use the card ID with other commands to drill into a specific card.
agent-cards cards details <card-id>
Retrieve the full card number (PAN), CVV, and expiry date for a specific card. Card data is decrypted from AES-256-GCM only on your explicit request.
agent-cards balance <card-id>
Quick balance check for a specific card. Returns the remaining funds without fetching the full card details.
MCP integration
Connect
to Claude
Give Claude direct access to your cards — create cards, check balances, and log payments without leaving the chat.
How it works
Four steps.
Zero friction.
Human
Step 01
Pre-approve the amount
Add your debit or credit card and choose how much your agent can spend. We place a hold for that amount — nothing is charged yet.
Agent
Step 02
Agent creates a card
When the agent needs to pay, it creates a virtual debit card for the exact amount — no more, no less.
Human approves before card is created
Agent
Step 03
Agent pays
The agent uses the card for a single transaction. Once used, the card is automatically cancelled.
Human approves before payment is made
Automatic
Step 04
Unused amount is released
Only the actual transaction amount is captured. Anything the agent doesn't spend is released — it never hits your card.
01
Instant issuance
Card is ready within seconds of payment. No waiting, no manual approval, no delays.
02
Single-use by default
Each card is locked to the amount you load. Limit exposure per agent, per task, per spend.
03
Works everywhere
Accepted anywhere Mastercard works online. If a site takes Mastercard, your agent can pay.
04
Human in the loop
You authorize every card creation and every payment before it happens. Agents propose, you approve.
05
Built for agents
Expose cards to any MCP-compatible AI with one config block. Claude, Cursor, and any MCP runtime.
What people are saying
This is exactly the kind of infrastructure I've been thinking about. Agents need to interact with the real world; payments, APIs, services etc. The plumbing layer for agentic systems is massively underbuilt right now.
Super useful framing. Scoped spend limits + agent-specific cards feels like the safest path for real autonomous workflows.

On point! There will be a million single person successful companies all over the world some day, all operating through AI agents

Finally, a debit card for AI Agents has come out. I wonder how the legal framework is set up.

this is really cool! definitely the right direction for agentic commerce moving forward
Feb 27
This is such a smart solution for keeping things secure! Love the idea of giving an agent its own spending limit.

Welp, that was fast: totally free* digital card issuer for your agent. Very cool. *: 'during beta'

FAQ
Common questions
How does payment work?
You add your debit or credit card once. When an agent creates an AgentCard, we place a pre-authorization hold for the requested amount. When the AgentCard is actually used, your card is only charged for the real transaction amount — not the full hold. No wallet, no prefunding, no leftover balances.
Does the agent spend money without my permission?
No. You authorize every card creation and every payment before it happens. The agent proposes an action, and you approve or deny it in real time.
What kind of card do I get?
A single-use virtual debit card. Each card has its own PAN, CVV, and expiry — accepted anywhere Mastercard is accepted online.
What if the agent spends less than the hold?
You're only charged for the actual transaction amount. The remaining hold is automatically released back to your card — nothing extra is charged.
Which AI agents can use it?
Any MCP-compatible agent — Claude, Cursor, or any MCP runtime. You can also copy card details into any other agent or tool manually.
How is my card data protected?
Card details are encrypted with AES-256-GCM and only decrypted on your explicit request. We never store raw card numbers.
