How to Use the Payfunnels MCP in OpenAI Agents SDK

Q: How do I authenticate Payfunnels with the OpenAI Agents SDK?

Pass your Vinkius single-endpoint token to MCPServerStreamableHttpParams when initializing the server stream. Your OpenAI Agents SDK agent will automatically discover the MCP tools without requiring manual schema definitions.

Q: How does Payfunnels handle token limits in OpenAI Agents SDK?

The server returns compact JSON payloads for tools like listpayments to keep token usage low. This ensures your OpenAI Agents SDK runs efficiently without hitting context window caps during active billing sessions.

Q: What is the setup process for this integration?

Install the package using pip install openai-agents and instantiate the HTTP server class with your Vinkius URL. Then, pass the MCP Server instance inside the mcpservers list to your Agent constructor to enable auto-discovery.

Generate Payfunnels payment links and manage subscriptions directly from your OpenAI Agents SDK workflows.

Perplexity

Build self-correcting billing handoffs

Hand off payment collection tasks to specialized agents using the `create_one_time_payment_link` tool. Your OpenAI Agents SDK pipeline routes billing queries to a dedicated checkout agent, which spins up custom links on demand and traces the execution in your OpenAI developer dashboard. When customers request plan changes, the billing agent triggers `create_recurring_payment_link` to transition them to subscription tiers. The SDK's built-in guardrails validate these link parameters before they execute, protecting your Stripe account from invalid payloads.

Automated subscription churn management

Stop losing recurring revenue to payment failures by letting your python agents monitor accounts. The agent checks user status via `list_subscriptions` and identifies accounts that require immediate billing intervention. If a customer requests a cancellation, your OpenAI Agents SDK agent uses `cancel_subscription` while logging the telemetry. This setup lets you build automated retention flows that offer discounts before finalizing the cancellation.

Secure refund handling via OpenAI Agents SDK

Run a secure billing agent that handles customer disputes by calling `refund_payment` safely. You define strict system prompts in the SDK to ensure the agent only refunds transactions after checking `get_payment_details` to verify the charge history. By connecting this MCP Server to your runtime, you give your support agent the exact tools it needs without exposing raw payment processor credentials. Every transaction lookup and refund action gets logged to your OpenAI platform for audit trails.

Setup guide

Set up Payfunnels 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 Payfunnels tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Payfunnels MCP in OpenAI Agents SDK

Pass your Vinkius single-endpoint token to `MCPServerStreamableHttpParams` when initializing the server stream. Your OpenAI Agents SDK agent will automatically discover the MCP tools without requiring manual schema definitions.

Yes, you can restrict tool access directly within the Agent constructor when passing the server list. This prevents autonomous agents from executing sensitive tools like `cancel_subscription` or `refund_payment` unless explicitly authorized.

The server returns compact JSON payloads for tools like `list_payments` to keep token usage low. This ensures your OpenAI Agents SDK runs efficiently without hitting context window caps during active billing sessions.

Install the package using `pip install openai-agents` and instantiate the HTTP server class with your Vinkius URL. Then, pass the MCP Server instance inside the `mcp_servers` list to your Agent constructor to enable auto-discovery.

Vinkius runs the server in an isolated V8 sandbox, meaning customer emails and subscription metadata are never cached. Your API credentials remain encrypted, so the agent only accesses payment links and subscription records during active MCP execution.
