Full subscriber control in OpenAI Agents SDK

You can push new contacts to your database by calling `create_subscriber` inside your agent logic. This avoids manual entry and keeps your mailing lists current as your agent processes incoming leads. Updating existing records happens just as fast with `update_subscriber`. Your agent handles the heavy lifting, ensuring your data stays clean without you touching a dashboard.

Draft and track content via MCP Server tools

Compose your next update using `create_email` and let the agent handle the heavy lifting. You get to maintain total control over your messaging while the agent manages the actual dispatch steps. Verification is simple when you call `get_email` to check the status of your recent drafts. The agent pulls the exact record you need, so you never guess what is currently in the queue.

Sync your metadata with automated tagging

Organize your audience segments by using `create_tag` to categorize users based on their activity. Your agent identifies trends and applies labels automatically during your daily operations. When you need to see the big picture, `list_tags` returns every category you have set up. It keeps your mailing lists organized without manual intervention from your team.

Setup guide

Set up Buttondown Alternative 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 Buttondown Alternative tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
