Openclaw Agentic Commerce Protocol

Agentic Commerce Protocol (ACP) Integration

Welcome to the Agentic Commerce Protocol (ACP) skill module for the GenPark/OpenClaw ecosystem! 🚀

This skill integrates the open standard co-developed by OpenAI and Stripe, enabling AI agents to autonomously handle full post-discovery transactional commerce flows. It provides capability negotiation, cart matching, Stripe Payment Token (SPT) delegation, and fulfillment/webhook tracking.

⚡ Quickstart & Testing

All scripts are written in native modern Node.js and require zero external npm dependencies.

1. Run the End-to-End Test Suite

Tests negotiation, scoped token delegation, order checkout, and idempotency protection against an active HTTP test server:

node scripts/test_acp_flow.js

2. Run the MCP Tool Dispatcher

Tests the Model Context Protocol tools exposed to LLM agents:

node scripts/acp_mcp_tool.js

3. Start the Mock Merchant Server

node scripts/mock_merchant_server.js
# Server running at http://localhost:8088

🤖 MCP (Model Context Protocol) Integration

To equip your AI agent (Anthropic Claude, OpenClaw, Antigravity, Cursor) with ACP tools, add the following to your MCP configuration:

{
  "mcpServers": {
    "agentic-commerce": {
      "command": "node",
      "args": ["path/to/scripts/acp_mcp_tool.js"],
      "env": {
        "ACP_MERCHANT_BASE_URL": "http://localhost:8088",
        "STRIPE_MERCHANT_ID": "acct_acp_demo"
      }
    }
  }
}

Available MCP Tools

Tool Name	Purpose
acp_negotiate_cart	Resolves cart subtotal, shipping choices, and dynamic sales taxes with merchant
acp_mint_payment_token	Mints a scoped single-use Stripe Payment Token (SPT) with customer consent
acp_create_checkout_session	Submits payment token and locks order creation
acp_track_order	Queries live fulfillment, tracking numbers, and delivery status

🛠️ Programmatic Usage

const ACPClient = require('./scripts/acp_client');

const client = new ACPClient({
  baseUrl: 'https://api.merchant.com', // Omit or set useMock: true for offline mode
  merchantId: 'acct_merchant_123'
});

async function buyProduct() {
  // 1. Negotiate checkout session
  const session = await client.negotiate({
    lineItems: [{ sku: 'PRO-RUNNER-9', quantity: 1, unit_price: 120.00 }],
    shippingAddress: { line1: '123 Market St', city: 'San Francisco', state: 'CA', postal_code: '94105', country: 'US' }
  });

  // 2. Mint single-use scoped payment token (SPT)
  const token = await client.mintStripePaymentToken({
    maxAmount: session.total_amount,
    customerConsent: true
  });

  // 3. Finalize order
  const order = await client.createCheckoutSession({
    sessionId: session.session_id,
    selectedShippingId: session.selected_shipping_id,
    paymentToken: token
  });

  console.log(`Order placed: ${order.order_id}, Tracking: ${order.fulfillment.tracking_number}`);
}

🔑 Core Features

• Authoritative Negotiation: Coordinates dynamic taxes, shipping rates, and stock availability directly from merchant APIs.
• Stripe Payment Token (SPT) Delegation: Eliminates credential exposure by scoping charges to specific merchants, amounts, and expiration times.
• Idempotency Protection: Safe network retries using client-generated idempotency keys.
• Fulfillment Tracking: Real-time order queries and carrier tracking updates.
