Perplexity

Automate Billing Recovery Contacts

`bulk_update_billing_contacts` and `update_billing_contacts` update recovery contacts for failing subscriptions directly through your OpenAI pipeline. Your agent identifies accounts with failing credit cards and updates their billing details in one sweep. Instead of writing custom API scripts, you let your agent handle the recovery logic through the MCP link. It checks your CRM, matches the billing contacts, and applies the updates instantly.

GDPR Data Removal via Churnkey MCP Server

`get_customer_gdpr_data` and `delete_customer_gdpr_data` handle user privacy requests without manual database queries. Your agent pulls stored data or purges it completely when a customer asks to be forgotten. This setup removes the risk of human error during manual compliance tasks. You set the rules, and the agent executes the deletions securely in the background.

Analyze Retention Sessions

`list_retention_sessions` and `get_retention_session_details` expose why customers are trying to cancel. Your agent reads exit survey responses and session details to categorize customer complaints. You get immediate access to cancellation trends. The agent feeds these insights into your retention playbook to trigger custom save offers.

Setup guide

Set up Churnkey 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 Churnkey tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Churnkey MCP in OpenAI Agents SDK

Install the OpenAI SDK first. Initialize the streamable HTTP client with your Vinkius endpoint URL and pass it to your Agent constructor.

Yes. The agent uses the bulk update tool to change multiple records in a single execution loop. You can use OpenAI's built-in guardrails to review these bulk changes before they go live.

Set up a specialized agent for retention analysis and another for billing updates. Pass the Churnkey tools to the billing agent so it only runs when a customer needs recovery help.

No. Vinkius handles the underlying authentication with Churnkey. Your agent only needs the single Vinkius endpoint token to access all eight tools.

Your retention sessions and billing contact details remain protected through Vinkius's zero-trust V8 sandbox environment. The connection is ephemeral, meaning no customer data is cached or stored on the proxy server during execution.
