How to Use the Commerce.js MCP in OpenAI Agents SDK

Q: How do I connect Commerce.js to my OpenAI Agents SDK pipeline?

Install the SDK via pip and initialize MCPServerStreamableHttp pointing to your Vinkius endpoint. Pass this server instance into your Agent constructor's mcpservers list to auto-discover Commerce.js tools like listproducts.

Build production-grade checkout agents using OpenAI Agents SDK to manage your Commerce.js store with strict guardrails.

Safe cart operations via OpenAI Agents SDK

This MCP Server exposes `create_cart` and `add_to_cart` directly to your OpenAI agent to build customer shopping sessions on the fly. Your agent can now spin up active carts and add items without you writing manual API wrappers for Commerce.js. Because you are using OpenAI's production SDK, you get built-in guardrails to validate these Commerce.js cart updates before execution. The agent safely modifies quantities using `update_cart_item` while you track the exact execution flow inside your OpenAI dashboard.

Guarded checkout flows and token generation

The `generate_checkout_token` and `capture_order` tools let your OpenAI agent finalize transactions when a customer is ready to buy. This moves the user from browsing to purchase without manual developer intervention. You don't have to worry about the agent hallucinating pricing or shipping data during this critical Commerce.js checkout step. The OpenAI Agents SDK forces validation checks on these tool calls, ensuring the payload matches your store's configuration before the order is placed.

Secure order lookups with agent handoffs

The `get_order` and `list_orders` tools allow your specialized support agents to check on customer shipments securely. This keeps sensitive customer records isolated to agents that actually need them. You can set up a triage agent that handles basic product questions using `list_products` and then hands off the conversation to a secure billing agent in OpenAI Agents SDK when an order lookup is requested. This keeps your Commerce.js secret keys safe while maintaining a smooth chat experience.

Setup guide

Set up Commerce.js MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Commerce.js tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Commerce.js tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Commerce.js tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Commerce.js Agent",
            instructions="You have access to Commerce.js tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Commerce.js MCP in OpenAI Agents SDK

Install the SDK via pip and initialize `MCPServerStreamableHttp` pointing to your Vinkius endpoint. Pass this server instance into your Agent constructor's `mcp_servers` list to auto-discover Commerce.js tools like `list_products`.

Yes, the SDK allows you to define pre-execution hooks that inspect the arguments for `generate_checkout_token` and `capture_order`. If the agent attempts to pass an invalid amount or cart ID, the guardrail blocks the call before it hits the Commerce.js API.

You configure a main router agent and two specialized agents. The router uses `list_products` for general browsing, but hands off the thread to a secure agent with access to `get_order` when a user asks about their specific receipt.

No, you don't. The OpenAI Agents SDK automatically inspects the schema of the running MCP Server and registers tools like `list_categories` and `create_cart` dynamically at runtime.

Your Commerce.js secret keys and customer order details are completely isolated within the Vinkius sandboxed environment. The OpenAI Agents SDK only sees the schema of tools like `get_order` and never has direct, unmonitored access to your raw backend credentials.
