Run Scans Securely with OpenAI Agents SDK

The `add_target` tool registers new external domains directly into your security boundary, while `trigger_scan` kicks off immediate vulnerability sweeps. Your OpenAI agent uses these tools to monitor shadow IT without manual intervention. The SDK enforces strict guardrails to prevent your agent from scanning unauthorized hosts. By managing these operations inside a secure MCP runtime, you prevent accidental scans while maintaining an up-to-date asset inventory.

Track Halo Security Vulnerabilities with This MCP Server

The `get_security_risk` tool pulls current risk ratings, and `list_issues` retrieves all active vulnerabilities across your external perimeter. This MCP server lets your agent flag critical exposures the second they surface. Your agent coordinates handoffs between triage and remediation workflows when a high-risk issue appears. You get full visibility into security risks directly within your OpenAI tracing dashboard.

Audit Halo DNS, Ports, and Certificates Automatically

The `list_open_ports` tool finds exposed services, while `list_dns_records` and `list_certificates` expose weak infrastructure configurations. Your agent parses this raw data to find expired TLS setups or forgotten subdomains. Instead of manual network audits, your OpenAI agent handles the heavy lifting by checking these endpoints sequentially. You get a clear picture of your actual attack surface without writing custom parser scripts.

Setup guide

Set up Halo Security 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 Halo Security tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Halo Security MCP in OpenAI Agents SDK

You pass your Halo API key as an environment variable to the Vinkius managed endpoint. The OpenAI Agents SDK then connects to this secure MCP server URL, handling all tool execution behind the scenes without exposing your credentials to the LLM.

Yes, you can control tool access using the MCP server configuration. If you want to prevent an agent from running `trigger_scan` but allow it to run `list_targets`, you simply configure the agent to only register specific tools during initialization.

The SDK relies on the underlying Vinkius infrastructure to manage connection pools. If your agent makes too many concurrent calls to `list_issues` or `list_open_ports`, the platform queues the requests to keep your API usage within Halo limits.

You can set up a routing agent that monitors overall risk using `get_security_risk`. When a critical issue is found, that agent hands off the task to a specialized remediation agent that pulls specific details using `get_issue`.

Your target lists, open port data, and vulnerability logs pass through an ephemeral V8 sandbox hosted by Vinkius. No security data is stored on Vinkius servers, keeping your perimeter details isolated to your OpenAI runtime and your Halo account.
