How to Use the Mail Blaze MCP in OpenAI Agents SDK

Q: Can my OpenAI Agents SDK setup schedule newsletters using Mail Blaze?

Yes, your agent can draft the newsletter using createnewcampaign and then dispatch it via sendemailcampaign. You can set up a verification step in your code to approve the draft before the send tool runs.

Run production-ready email campaigns directly from your OpenAI Agents SDK setup with secure, auto-discovered Mail Blaze tools.

Automate subscriber sync in OpenAI Agents SDK

This MCP Server exposes the `add_subscriber_to_list` tool to handle inserting new contacts into your lists instantly. Your agent calls this tool whenever a user signs up, bypassing manual database exports and CSV uploads. You can also use `update_list_subscriber` and `delete_list_subscriber` to keep your CRM and email lists aligned. The SDK handles the schema mapping, so your agent knows exactly which fields to update without breaking.

Programmatic campaign creation and deployment

The `create_new_campaign` tool lets your agent draft marketing campaigns using raw JSON inputs. It reads your current templates, structures the body, and prepares the campaign for review or immediate dispatch. When you are ready to go live, the `send_email_campaign` tool triggers the actual delivery. This lets you build fully autonomous loops where one agent drafts the copy and another schedules the broadcast.

Inspect live metrics and list structures

This Mail Blaze MCP integration lets the `get_campaign_details` tool retrieve performance metrics and delivery statuses directly into your agent's context window. Your agent uses this data to decide if a follow-up email is necessary. Running `list_subscriber_lists` and `list_list_subscribers` lets your system inspect current audiences before sending. It prevents double-sending errors and keeps your target lists clean.

Setup guide

Set up Mail Blaze 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 Mail Blaze tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Mail Blaze MCP in OpenAI Agents SDK

Install the SDK and pass the Vinkius HTTP endpoint into your agent's server list. The SDK automatically discovers all nine tools, making them instantly available to your agent without manual schema definition.

Yes, your agent can draft the newsletter using `create_new_campaign` and then dispatch it via `send_email_campaign`. You can set up a verification step in your code to approve the draft before the send tool runs.

The SDK relies on your connection configuration to manage request flow. If the Mail Blaze API returns a rate limit error, you should configure your HTTP client wrapper to back off and retry the request.

Yes, you can control tool access by filtering the exposed tools during server initialization. This prevents the agent from calling destructive tools like `delete_list_subscriber` while still allowing it to add contacts.

All subscriber email addresses and list records are processed inside Vinkius's isolated V8 sandboxes. Your API keys are encrypted at rest, and the server only transmits data to the official Mail Blaze API endpoint over HTTPS.
