Overview

AgentCard MCP Server

Give your AI agent a debit card. AgentCard lets AI agents create and spend virtual Mastercard debit cards — each with a fixed budget, real card credentials, and full MCP integration.

Features

MCP-native: One config block connects to Claude Code, Claude Desktop, Cursor, or any MCP client
Human-in-the-loop: Card funding requires approval via Stripe Checkout
Single-use by design: Cards are disposable with fixed limits, no overdraft possible
AES-256-GCM encryption: Card credentials encrypted at rest per-card
Instant issuance: Cards ready in seconds after funding

Quick Setup

npx agent-cards signup       # Create account (one-time)
npx agent-cards setup-mcp    # Auto-configures Claude Code

Restart Claude Code and your agent can create and spend virtual cards.
