How to Use the AT&T Messaging MCP in OpenAI Agents SDK

Q: Can OpenAI Agents SDK handle bulk AT&T Messaging campaigns?

Yes. The agent can execute sendbulksms to hit up to 164 recipients at once. We recommend setting strict guardrails to prevent accidental spam blasts.

Q: Does the AT&T Messaging MCP Server support media attachments?

You can attach images and video. The agent uses the sendmms tool and requires a valid media URL alongside the recipient phone number.

Q: What happens when a message fails to deliver?

The agent catches the failure state. It checks getmessagestatus and can trigger a fallback action, like sending an email instead.

Send SMS campaigns with OpenAI Agents SDK

This AT&T Messaging MCP Server lets your agent text users without going rogue. By passing the endpoint to the Agent constructor, you give it direct access to the API. It handles single notifications via `send_sms` or media blasts using `send_mms`. The built-in guardrails keep things safe. Before firing off a `send_bulk_sms` job, you can enforce human-in-the-loop approval. Tracing in the OpenAI dashboard shows exactly which numbers got texted.

Manage shortcodes and inbound replies

This MCP Server turns shortcode provisioning from a manual chore into a programmatic task. One specialized agent calls `create_shortcode` to grab a new number for a marketing push. It tracks the activation timeline autonomously. Another agent monitors the inbox. It runs `get_inbound_messages` to catch STOP commands and processes opt-outs immediately. When the campaign ends, the agent cleans up by executing `delete_shortcode`.

Track delivery and audit history

Tracking delivery states is the primary job of this MCP Server. When a critical OTP fails, your system needs to know immediately. The agent pulls delivery states using `get_message_status` to confirm receipts. Compliance reporting happens in the background. You just tell the agent to compile last month's logs. It triggers `list_messages` and formats the timestamps and sender data into a clean report.

Setup guide

Set up AT&T Messaging 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 AT&T Messaging tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
