How to Use the Duo Security (Two-Factor Authentication API) MCP in OpenAI Agents SDK

Q: How do I handle asynchronous MFA loops using the Duo Security (Two-Factor Authentication API) with the OpenAI Agents SDK?

You trigger the push notification using the auth tool, which returns a transaction ID. The agent then enters a polling loop using authstatus to monitor the transaction until the user approves or rejects the prompt.

Q: What happens if my OpenAI Agents SDK pipeline triggers too many telephony requests?

The agent can run gettelephonycredits to check your remaining balance before sending SMS or voice prompts. If credits are low, you can programmatically execute settelephonycredits or alert your admin team to prevent auth failures.

Secure your production OpenAI Agents SDK pipelines with direct Duo Security multi-factor authorization and user provisioning.

Perplexity

Run `auth` checks directly from OpenAI Agents SDK

The `auth` tool lets your OpenAI Agents SDK trigger push notifications or phone call verifications directly during runtime execution. This ensures that high-risk operations in your agentic workflows require explicit human approval before proceeding. Your agent polls for completion using `auth_status` to verify the user approved the prompt. If the user denies the request or the timeout expires, the agent halts the pipeline immediately to prevent unauthorized access.

Automate user provisioning inside this MCP Server

The `create_user` tool handles instant enrollment when new team members need access quickly. Your agent can ingest raw directory data and write it directly to your Duo environment. For larger batches, the agent switches to `bulk_create_users` to register up to 100 users in a single API call. This eliminates manual entry errors during large onboarding events.

Manage MSP sub-accounts and billing editions

The `list_accounts` tool gives your agent visibility into child accounts for MSP partner setups. This allows your agent to audit client environments and verify configuration parity using this MCP Server. When an account needs an upgrade, the agent runs `set_billing_edition` to modify service tiers programmatically. It keeps track of overhead by checking `get_telephony_credits` before triggering voice or SMS verification runs.

Setup guide

Set up Duo Security (Two-Factor Authentication API) 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 Duo Security (Two-Factor Authentication API) tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Duo Security (Two-Factor Authentication API) tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

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

asyncio.run(main())

Common questions about Duo Security (Two-Factor Authentication API) MCP in OpenAI Agents SDK

Your agent auto-discovers all 18 tools during initialization when you register the MCPServerStreamableHttp instance. It maps functions like `preauth` and `list_users` directly into the agent's toolset without manual schema definitions.

Yes, you enforce boundaries by setting strict API scopes on your Duo integration keys before connecting the MCP Server. Your agent will only be able to invoke tools like `ping_auth` or `modify_user` that match the permissions of your underlying credentials.

You trigger the push notification using the `auth` tool, which returns a transaction ID. The agent then enters a polling loop using `auth_status` to monitor the transaction until the user approves or rejects the prompt.

The agent can run `get_telephony_credits` to check your remaining balance before sending SMS or voice prompts. If credits are low, you can programmatically execute `set_telephony_credits` or alert your admin team to prevent auth failures.

This server processes sensitive data including phone numbers, emails, and transaction statuses within an isolated V8 sandbox. No database stores your integration keys or user credentials, ensuring all transmission between your client and the Duo API remains ephemeral.
