Automated Bill Creation via OpenAI Agents SDK

Your OpenAI Agents SDK workflow can now spin up payment requests instantly using the `create_bill` tool. This means your billing agent can draft a bill, run it through your custom safety guardrails, and send it to a customer without manual intervention. The agent uses `list_collections` to find the correct target before firing off the payment request. Because OpenAI handles tracing natively, you can watch the entire collection selection and bill generation step inside your developer dashboard.

Safe Collection Management with MCP Server Tools

Running financial operations in production requires strict boundaries, which is where the `activate_collection` and `deactivate_collection` tools come in. This MCP Server lets your agent toggle payment gateways based on real-time inventory or customer status. You can set up specialized agent handoffs so that only a supervisor agent can invoke `delete_bill`. This prevents rogue LLM actions from wiping out pending invoices in your Billplz account.

Real-Time Transaction Auditing

Keep your financial ledger accurate by using `list_transactions` to query payment states directly via this MCP integration. The agent invokes `get_bill` to verify whether a customer has actually paid before unlocking digital goods. It can also call `get_fpx_banks` to check local bank availability before suggesting payment methods to the user. This keeps your agentic workflow fast and grounded in actual API data.

Setup guide

Set up Billplz 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 Billplz tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Billplz MCP in OpenAI Agents SDK

Install the package and pass the Billplz Vinkius URL to the server streamable HTTP constructor. The OpenAI Agents SDK automatically detects all eleven tools, making them instantly available to your agent.

Yes, you can enforce this through the SDK's built-in guardrails or by setting up specialized agent handoffs. For instance, you can restrict the `delete_bill` tool to a supervisor agent while letting worker agents run `get_bill` freely.

The SDK relies on the underlying Vinkius infrastructure to handle connection pooling and transport. If Billplz limits your requests during heavy billing runs, the SDK's async context manager handles the stream gracefully without crashing your agent.

No, Vinkius handles the authentication for you securely. Your agent only needs the single endpoint token to execute tools like `get_bank_account` safely.

All payment data, bill details, and bank account information processed by the tools run inside an isolated, ephemeral V8 sandbox. No transaction history is stored on Vinkius servers, ensuring your customer records remain completely private.
