How to Use the Customer.io MCP in OpenAI Agents SDK

Q: How do I connect Customer.io to OpenAI Agents SDK?

Pass the Vinkius endpoint using MCPServerStreamableHttp into your Agent constructor. The SDK auto-discovers all twelve tools from this MCP Server instantly. You just need to set the context manager to handle the async connection.

Q: Can OpenAI Agents SDK read Customer.io campaign stats?

Yes, the agent calls getcampaignperformance to read open and click rates. You view these exact tool calls in your OpenAI tracing dashboard to verify what the agent checked.

Q: What happens if the API goes down while my agent runs?

The agent uses getconnectionstatus to verify health before executing sends. If the endpoint fails, OpenAI's execution guardrails catch the error and prevent hallucinated success responses.

Q: Does the OpenAI Agents SDK support sending Customer.io transactional messages?

It handles individual sends through the sendtransactionalemail tool. You also review past sends by calling listtransactionalmessages to ensure duplicates do not go out.

Connect Customer.io to OpenAI Agents SDK to trigger broadcasts and track campaigns safely with built-in execution guardrails.

Run Customer.io campaigns via OpenAI Agents SDK

Your production agent needs to fire off messages without making mistakes. Connecting this MCP Server gives your agent direct access to `list_active_campaigns` and `list_scheduled_broadcasts`. OpenAI's built-in guardrails validate every action before execution, ensuring the agent never blasts the wrong audience. Handoffs between specialized agents work perfectly here. One agent analyzes user behavior, then hands off to a communication agent that triggers `dispatch_broadcast`. You see the entire flow in the OpenAI tracing dashboard, keeping your messaging pipeline predictable and safe.

Fetch profiles and track performance

Checking message histories usually requires opening another browser tab. Now your Python agent pulls exact profiles using `get_customer_details` and checks segment lists with `list_segment_members`. The SDK auto-discovers these tools the moment you pass the server to the Agent constructor. Performance metrics become part of your automated reporting. The agent calls `get_campaign_performance` and formats the stats for your team. Deployed products require speed, so you set `cacheToolsList=True` to keep these lookups fast and reduce overhead.

Send transactional emails automatically

Password resets and receipts cannot wait for batch processing. Your system triggers `send_transactional_email` the exact moment a user completes an action. The agent handles the timing and payload formatting automatically without human intervention. Checking API health happens in the background. If `get_connection_status` fails, the SDK's safety constraints prevent the agent from retrying blindly. You build a resilient MCP Server integration that respects rate limits and fails gracefully.

Setup guide

Set up Customer.io 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 Customer.io tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
