🦞 Stripe Agents Implementation Plan

1.1 Stripe Account Preparation

• Create a Stripe account (or use existing)
• Generate a Restricted API Key (RAK) with specific permissions
  • Tool availability = RAK permissions
  • Start with read-only for testing, expand as needed

1.2 Choose Integration Path

1.3 Environment Setup

# Python
pip install stripe-agent-toolkit

# TypeScript
npm install @stripe/agent-toolkit

# MCP (local)
npx -y @stripe/mcp --api-key=YOUR_RAK

2.1 Basic Agent Structure (Python example)

stripe_agent/
├── agent.py          # Main agent with Stripe tools
├── config.py         # API keys, permissions
├── tools/
│   ├── payments.py   # Payment-specific workflows
│   ├── customers.py  # Customer management
│   └── billing.py    # Subscriptions, invoices
└── utils/
    └── validation.py # Input sanitization

2.2 Key Tool Categories

3.1 Customer Support Agent

• Look up customer by email
• View payment history
• Process refunds (with approval)
• Update customer details

3.2 Billing Operations Agent

• Create/manage subscriptions
• Generate invoices
• Handle payment failures
• Apply discounts/coupons

3.3 Sales/Commerce Agent

• Create Payment Links dynamically
• Product catalog queries
• Price calculations with tax
• Order status tracking

3.4 Reporting Agent

• Balance reports
• Revenue analytics
• Subscription metrics
• Transaction reconciliation

4.1 With OpenAI Agent SDK

from stripe_agent_toolkit.openai import create_stripe_agent_toolkit

toolkit = await create_stripe_agent_toolkit(secret_key="rk_test_...")
agent = Agent(
    name="Stripe Agent",
    tools=toolkit.get_tools()
)

4.2 With MCP (for Claude/Cursor)

// claude_desktop_config.json
{
  "mcpServers": {
    "stripe": {
      "command": "npx",
      "args": ["-y", "@stripe/mcp", "--api-key=STRIPE_SECRET_KEY"]
    }
  }
}

4.3 With LangChain

from stripe_agent_toolkit.langchain import create_stripe_agent_toolkit

toolkit = await create_stripe_agent_toolkit(secret_key="rk_test_...")
tools = toolkit.get_tools()
# Pass to LangChain agent executor

5.1 Test Environment

• Use Stripe test mode (rk_test_*)
• Create test customers/products
• Simulate payment flows

5.2 Validation Checklist

[ ] All API calls use RAK (not secret key)
[ ] Destructive ops require confirmation
[ ] Error handling for failed API calls
[ ] Rate limiting awareness
[ ] Idempotency keys for critical operations

5.3 Monitoring

• Stripe Dashboard webhooks
• Agent action logging
• Cost tracking (API calls, LLM tokens)

6.1 Scaling

• Connection pooling for Stripe SDK
• Caching for frequent queries (products, prices)
• Queue system for bulk operations

6.2 Compliance

• PCI DSS: Agent doesn't handle raw card data (Stripe does)
• GDPR: Customer data handling
• Audit trails for all operations

6.3 Cost Management

• Use @stripe/token-meter to bill LLM usage to customers
• Monitor Stripe API rate limits
• Implement retry logic with backoff
