Agent Card — Payment Skill

Give your AI agent a virtual MasterCard. Agent Card lets agents autonomously create, fund, and manage virtual MasterCard cards by paying in USDC on the Stellar blockchain.

What It Does

Create cards — Issue virtual MasterCards with per-card spend limits
Fund cards — Top up existing cards with USDC
Manage cards — List, freeze, unfreeze, and inspect card details
On-chain payments — Every transaction uses the x402 protocol on Stellar with verifiable on-chain proof

Setup

npx @asgcard/cli onboard -y

This creates a Stellar wallet (

~/.asgcard/wallet.json

), configures the MCP server, and installs the payment skill. Your agent is ready to pay in under 30 seconds.
