How to Use the Face++ / Megvii MCP in OpenAI Agents SDK

Q: How do I connect the Face++ / Megvii MCP Server to my OpenAI Agents SDK pipeline?

Install openai-agents and initialize MCPServerStreamableHttp with your Vinkius endpoint. Pass this server instance directly to your agent constructor, and the SDK automatically maps all ten vision tools for immediate use.

Q: How does the OpenAI Agents SDK handle high-concurrency requests to Face++ / Megvii?

Set cacheToolsList=True in your connection parameters to avoid redundant schema lookups. The SDK caches the tool definitions, which reduces latency when your system executes frequent comparefaces operations.

Q: What happens if a face search fails inside the agent loop?

When searchface finds no matching identity, the tool returns a clear empty result. Your agent catches this response and can trigger a fallback flow, like registering a new user via createfaceset.

Run enterprise-grade identity checks in production with OpenAI Agents SDK and our managed Face++ / Megvii MCP Server.

Secure Biometric Verification

The `compare_faces` tool matches two faces to verify identity with mathematical precision. Your OpenAI agents use this tool to verify users during high-risk steps, automatically logging the confidence scores directly to your OpenAI tracing dashboard. You set up the connection using `MCPServerStreamableHttp` in your Python code. The agent inspects the face images, catches low-quality inputs using `detect_face` before running the comparison, and executes the entire flow inside a sandboxed environment.

Automated FaceSet Management

The `create_faceset` tool builds isolated directories of face tokens on the Megvii platform. Your OpenAI agents manage these directories dynamically, adding new biometric records or cleaning up expired ones. When an agent needs to update user records, it calls `add_face_to_faceset` and `remove_face_from_faceset`. This MCP Server integration lets the SDK's built-in guardrails validate these actions against your system schemas before any API call goes out, ensuring no rogue agent wipes your database.

Advanced Gesture and Skeleton Analysis

The `gesture_detect` tool captures hand movements from video frames to confirm live human presence. OpenAI agents use this to block static photo spoofing attempts. Your agent coordinates this check with `skeleton_detect` and `detect_body` to map physical posture. This multi-step validation runs through native agent handoffs, keeping your primary identity agent focused on core verification while specialized sub-agents handle the physical telemetry.

Setup guide

Set up Face++ / Megvii 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 Face++ / Megvii tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Face++ / Megvii MCP in OpenAI Agents SDK

Install `openai-agents` and initialize `MCPServerStreamableHttp` with your Vinkius endpoint. Pass this server instance directly to your agent constructor, and the SDK automatically maps all ten vision tools for immediate use.

Yes. You control tool access at the SDK level by defining custom agent instructions or filtering the tool definitions before passing them to the agent. This prevents agents from calling destructive tools like `remove_face_from_faceset` unless authorized.

Set `cacheToolsList=True` in your connection parameters to avoid redundant schema lookups. The SDK caches the tool definitions, which reduces latency when your system executes frequent `compare_faces` operations.

When `search_face` finds no matching identity, the tool returns a clear empty result. Your agent catches this response and can trigger a fallback flow, like registering a new user via `create_faceset`.

Every image payload and biometric facial template processed by `detect_face` passes through an ephemeral V8 sandbox. Vinkius does not store your face coordinates or raw images, and the endpoint token handles authentication securely without exposing your raw API keys to the agent.
