How to Use the Mailjet MCP in OpenAI Agents SDK

Q: Can OpenAI Agents SDK trigger Mailjet campaigns automatically?

Yes. Your agent uses the listmarketingcampaigns tool to check for active campaigns and can execute logic based on that status.

Trigger transactional emails and manage subscriber lists directly from your OpenAI Agents SDK workflow.

Perplexity

Automate transactional email delivery

Your agent uses `send_transactional_email` to push notifications through the Mailjet v3.1 API. It handles the JSON payload structure required for reliable delivery. This setup removes manual relay configuration. Your agent sends alerts the moment your internal logic hits the trigger, keeping your event-driven architecture tight.

Sync contacts with OpenAI Agents SDK

Use `create_new_contact` and `add_contact_to_list` to maintain your database state. Your agent reads incoming data and updates your lists without leaving the execution flow. This ensures your CRM stays current. When the agent identifies a lead, it pushes the data directly into your Mailjet environment, avoiding batch processing delays.

Analyze performance data inside your MCP Server

Query your marketing reach using `get_campaign_performance` and `get_campaign_details`. The agent pulls these metrics to provide feedback on your latest outreach. You get visibility into open rates and clicks without switching tabs. This MCP Server gives your agent the data it needs to adjust messaging strategy on the fly.

Setup guide

Set up Mailjet 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 Mailjet tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
