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.
