How to Use the CS-Cart MCP in OpenAI Agents SDK

Q: Can my OpenAI Agents SDK system read CS-Cart product options?

Yes. The getproduct tool returns full details including feature combinations and multi-vendor pricing. Your agent parses this payload automatically.

Build production-grade agents that manage your CS-Cart marketplace with the OpenAI Agents SDK guardrails.

OpenAI Agents SDK Order Management

`get_order` and `list_orders` let your agent read transaction details directly from your CS-Cart store. You can pull line items, billing addresses, and payment statuses to feed into automated customer support logic. Passing these ecommerce tools through the OpenAI Agents SDK means every action gets validated against your predefined safety constraints. Your agent won't execute a refund or read sensitive shipping methods without passing the checks you configured.

Traceable Marketplace Audits

`list_vendors` and `list_users` expose the multi-vendor structure of your marketplace directly to your Python application. Your script grabs company profiles, contact info, and role assignments in one single pass. Since you manage this MCP Server connection through the OpenAI dashboard, you get full tracing on every API call. You see exactly which vendor profiles the agent checked before making an approval decision.

Automated Tax & Shipping Checks

`list_taxes` and `list_shippings` pull the geographic rules and carrier rates currently active in your database. This gives your agent the exact numbers needed to calculate landed costs for B2B buyers. Handoffs between specialized agents work perfectly here. One agent pulls the shipping constraints via this MCP integration, then hands the raw data to a quoting agent that formats the final proposal.

Setup guide

Set up CS-Cart 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 CS-Cart tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate CS-Cart 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="CS-Cart Agent",
            instructions="You have access to CS-Cart tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about CS-Cart MCP in OpenAI Agents SDK

Install the package with pip install openai-agents. Create an MCPServerStreamableHttp instance pointing to your Vinkius endpoint token and pass it to your Agent constructor.

Yes. The `get_product` tool returns full details including feature combinations and multi-vendor pricing. Your agent parses this payload automatically.

It does. You can assign the catalog tools to one agent and the order tools to another. The SDK manages the state transfer between them seamlessly.

Discovery happens on initialization. Set cacheToolsList=True in your parameters to skip the discovery phase on subsequent runs and speed up execution.

Vinkius runs your connection in an ephemeral V8 Isolate sandbox. When your agent calls `get_order`, the line-item details and customer billing boundary data pass straight to your OpenAI environment. We never store your transaction history.
