How to Use the Halo Security MCP in AutoGen

Q: Can the agents track trends in our security posture over time?

Yes. An agent can call getsecurityrisk to pull historical risk scores and analyze whether your security posture is improving or degrading, then write a summary report for your team.

Let your AutoGen security and development agents debate risk priority and automate target scanning in real time.

Perplexity

Multi-agent security debate and triage

Build a multi-agent workflow where a security agent calls `get_security_risk` and `list_issues` to debate risk priority with a developer agent. The security agent analyzes threats and presents the raw vulnerability findings to the developer agent to demand a fix. Meanwhile, the developer agent can check `list_technologies` to see if a reported library is actually active or just a false positive. This debate ensures your team only spends time fixing real, verified risks instead of chasing phantom warnings.

Automated target onboarding with AutoGen MCP Server

When your infrastructure agent provisions a new server, the security agent uses `add_target` to register the host for monitoring immediately. It then calls `trigger_scan` to establish a security baseline before the server goes live. Once the scan finishes, the agent checks `list_scans` and pulls any immediate findings using `list_issues`. If any critical exposures are found, the agent can automatically alert your DevOps channel to halt the deployment.

Continuous perimeter monitoring via agents

Set up an autonomous agent loop that calls `list_dns_records` and `list_open_ports` to detect unapproved changes in your public perimeter. The agent compares these findings against your baseline policy. If it discovers an unauthorized port, it calls `get_issue` to evaluate the severity. The agent can then coordinate with your firewall agent to close the port or flag it for manual review by your security team.

Setup guide

Set up Halo Security MCP in AutoGen

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] package
Active Vinkius subscription with a valid endpoint token

1

Install AutoGen with MCP
Run pip install "autogen-ext[mcp]" autogen-agentchat. The MCP extension includes mcp_server_tools for stateless tool access.
2

Fetch tools from the MCP
Call mcp_server_tools(SseServerParams(url=...)) with your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Run your agent
Pass the tools to AssistantAgent and call agent.run(). The agent invokes Halo Security tools and returns structured results.

agent.py

from autogen_ext.tools.mcp import SseServerParams, mcp_server_tools
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

tools = await mcp_server_tools(server_params)

agent = AssistantAgent(
    name="Halo Security_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent Halo Security data")
print(result.messages[-1].content)

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] + autogen-agentchat
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Same packages as above. McpWorkbench is ideal when your agent needs stateful sessions across multiple tool calls.
2

Use McpWorkbench as context manager
Wrap your agent in async with McpWorkbench(...) to maintain shared state and resources. The workbench manages the full MCP session lifecycle.
3

Run with workbench
Pass workbench=workbench to your agent. State is preserved across multiple tool calls within the same session.

agent.py

from autogen_ext.tools.mcp import McpWorkbench, SseServerParams
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

async with McpWorkbench(server_params) as workbench:
    agent = AssistantAgent(
        name="Halo Security_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent Halo Security data")
    print(result.messages[-1].content)

Common questions about Halo Security MCP in AutoGen

Agents share tool outputs within their group conversation history. When one agent calls `list_targets`, the resulting JSON payload is visible to all other agents in the chat, allowing them to collaborate on the remediation plan.

Yes, you can register the MCP tools only with specific agents. For example, you can give your security agent access to `trigger_scan` and `add_target`, while keeping your developer agent restricted to read-only tools like `list_issues`.

The MCP adapter in the AutoGen extension translates the JSON schemas automatically. Your agents will understand the input parameters for tools like `list_open_ports` and `list_certificates` without any manual mapping.

Yes. An agent can call `get_security_risk` to pull historical risk scores and analyze whether your security posture is improving or degrading, then write a summary report for your team.

Your TLS certificate data and software technology stacks are processed within secure, isolated runtime environments. We use zero-trust protocols, ensuring your sensitive infrastructure details never persist outside your active AutoGen session.
