Enable agent debate with Face++ / Megvii

Assign `compare_faces` to a verification agent while another agent monitors for errors. They debate the similarity scores until they reach a consensus on the identity. You get a more reliable decision because multiple agents check the logic of the API response. This prevents single-point-of-failure errors in your security flow.

Coordinate vision tasks in AutoGen

Use `detect_face` and `detect_body` across different agents to build a full situational analysis. One agent reports on the faces found, while another reports on the body count. They exchange this information to form a complete picture of the scene. You define the rules of their conversation and how they reconcile conflicting data.

Deploy this MCP Server across agents

Pass the tool list to your AssistantAgent constructor to give every participant access to the suite. Your agents share the workload of calling `gesture_detect` or `skeleton_detect`. This setup allows for specialized agents that focus on specific types of visual analysis. Your system scales as you add more agents to the conversation.

Setup guide

Set up Face++ / Megvii 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 Face++ / Megvii 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="Face++ / Megvii_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent Face++ / Megvii 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="Face++ / Megvii_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent Face++ / Megvii data")
    print(result.messages[-1].content)

Common questions about Face++ / Megvii MCP in AutoGen

You define two agents with access to the same tools. They compare outputs and discuss the validity of the results until they agree on a final answer.

Yes. The tools are shared across the group. Each agent can trigger a request based on its assigned role in the debate.

The adapter handles the schema conversion for you. You just pass the tools list to your agent and the framework manages the communication.

You can program your agents to check local cache or use conditional logic before calling the API. This minimizes redundant calls during the debate process.

The data is shared only between the agents you explicitly include in the conversation. You control the scope of the dialogue and the visibility of the returned biometric information.
