How to Use the Invoiced MCP in OpenAI Agents SDK

Q: How do specialized OpenAI Agents SDK workers handle Invoiced credit notes?

You can assign a specific agent to look up balances using listcreditnotes. If a dispute arises, that agent passes the context to a billing agent who updates the customer profile using getcustomer.

Stop manually chasing invoices. Let your OpenAI Agents SDK coordinate billing workflows directly through our secure MCP Server.

Automate Billing Runs via OpenAI Agents SDK

When your production agents run billing cycles, they need direct access to ledger data. This integration lets your agents call `create_invoice` and `list_payments` without manual oversight. You don't have to write custom glue code to reconcile accounts. The OpenAI Agents SDK automatically handles tool discovery during session initialization. By using `check_invoiced_status`, the agent verifies connection health over the MCP link before running high-volume invoice generation runs.

Safe AR Workflows with Guardrails

Handing financial actions to an agent is risky without safety limits. The OpenAI Agents SDK lets you configure validation guardrails before executing `create_customer` or issuing credit notes. This keeps your automated collections safe. You can trace every single payment lookup via the OpenAI developer dashboard. If an agent calls `get_invoice` on the MCP Server to check a balance, you see the exact payload and decision path in your logs.

Reconcile Ledgers Using Specialized Agent Teams

One agent checks balances while another handles customer disputes. Using the OpenAI Agents SDK, you can set up specialized handoffs to coordinate complex accounts receivable tasks. It keeps your code modular. An agent can scan past-due accounts using `list_invoices` and pass the context to a collections agent. That agent then fetches client contact info using `get_customer` to initiate follow-ups.

Setup guide

Set up Invoiced 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 Invoiced tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Invoiced MCP in OpenAI Agents SDK

The SDK connects via the Vinkius single endpoint token. You pass the secure HTTP URL directly to your MCPServerStreamableHttp setup, and Vinkius handles the underlying API headers safely.

Yes. For heavy production jobs, set cacheToolsList=True in your SDK configuration to prevent redundant schema fetches. This speeds up calls to `create_invoice` and `list_payments` during large batch runs.

You can assign a specific agent to look up balances using `list_credit_notes`. If a dispute arises, that agent passes the context to a billing agent who updates the customer profile using `get_customer`.

Run pip install openai-agents first. Then, initialize MCPServerStreamableHttp with your Vinkius URL and pass it to the Agent constructor inside an async context manager. This establishes the MCP connection safely.

All customer names, billing histories, and payment statuses remain inside the secure V8 isolate sandbox. Vinkius processes these financial transactions ephemerally, meaning no persistent storage of your ledger records on our servers.
