How to Use the Coupa MCP in OpenAI Agents SDK

Q: Can the OpenAI Agents SDK handle multi-agent handoffs for Coupa approvals?

Yes. You design one agent to draft orders using createpurchaseorder and another to handle approvals via approvepurchaseorder. The SDK manages the state handoff between them automatically.

Run production-grade procurement pipelines by connecting the Coupa MCP Server directly to your OpenAI Agents SDK.

Secure procurement runs through the OpenAI Agents SDK

The Coupa MCP Server exposes tools like `approve_purchase_order` and `create_purchase_order` to your Python agents with zero manual configuration. Your deployment gets immediate access to the entire procurement workflow, allowing specialized agents to build, check, and sign off on orders based on your organizational rules. OpenAI's built-in guardrails validate every single parameter before your agent executes a purchase order. You get complete execution tracing in your dashboard, ensuring every financial boundary state change is logged and audited.

Automate vendor checks and contract audits

This server gives your agent the power to query active agreements using `list_contracts` and pull profiles via `get_supplier_details`. Instead of writing custom API integration code, your agents discover these capabilities dynamically. When an agent spots an invoice discrepancy, it hands off the task to a specialized vendor agent. That agent pulls tax IDs and payment terms through `list_suppliers` to resolve the mismatch without human intervention.

Deep visibility into spending and invoices

Your agent monitors actual spend against budgets by calling `list_invoices` and `list_requisitions`. It pulls raw financial data directly from your instances to verify payment statuses and active approval steps. If a custom query is needed, the agent runs `query_coupa_resource` to fetch raw JSON payloads directly. This keeps your financial data accurate and up to date across your entire agent network.

Setup guide

Set up Coupa 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 Coupa tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Coupa MCP in OpenAI Agents SDK

Install openai-agents via pip. Initialize the connection using MCPServerStreamableHttp with your Vinkius endpoint URL, and pass it directly to your Agent constructor.

Yes. You design one agent to draft orders using create_purchase_order and another to handle approvals via approve_purchase_order. The SDK manages the state handoff between them automatically.

The SDK uses built-in guardrails to validate tool arguments before execution. This ensures your agent doesn't submit an order with missing line items or invalid accounting allocations.

It caches the tool definitions locally on startup. This reduces latency on subsequent agent turns, allowing faster lookups when querying invoices or suppliers.

All financial payloads pass through a zero-trust, ephemeral V8 Isolate sandbox. Vinkius handles the authentication tokens directly, meaning your raw Coupa credentials are never exposed to the LLM or stored in persistent logs.
