Question 1

What is Agent Cards and how does it benefit AI agents?

Accepted Answer

Agent Cards empowers AI agents to autonomously create, manage, and spend prepaid virtual Visa cards with fixed budgets for online transactions. This allows agents to handle their own payments securely and efficiently, eliminating the need for human intervention in routine online spending.

Question 2

How do AI agents create and use these virtual cards?

Accepted Answer

AI agents can use tools like `create_card` to generate new prepaid Visa cards with a specified USD budget. They can then utilize `x402_fetch` for automated payments on websites that return a 402 payment required response, or access card details with user approval for manual inputs.

Question 3

What security features does Agent Cards provide?

Accepted Answer

Each virtual card is created with a fixed USD budget, preventing overspending. Users can monitor card balances, expiry dates, and status. Accessing decrypted card credentials (PAN, CVV, expiry) often requires explicit human approval via email, adding a critical layer of security and control.

Question 4

Is Agent Cards compatible with popular AI development environments?

Accepted Answer

Yes, Agent Cards offers streamlined setup for popular MCP clients like Claude Code through a simple CLI command (`npx agent-cards setup-mcp`). It also provides flexible HTTP and stdio configuration options for seamless integration with other AI development environments and custom setups.
