What is the Face++ / Megvii MCP Server?
Empower your AI agent to orchestrate your computer vision operations with Face++ (Megvii), the dominant facial recognition platform in China. By connecting Face++ to your agent, you transform complex image analysis and identity verification into a natural conversation. Your agent can instantly detect faces, compare similarities between photos, search within face databases (FaceSets), and analyze human body skeletons or gestures without you ever needing to navigate the comprehensive web console. Whether you are conducting KYC audits or monitoring visual content, your agent acts as a real-time vision intelligence assistant, providing accurate and fast results from a single, unified source.
What you can do
- Face Orchestration — Detect faces in images and retrieve detailed attributes like age, gender, and emotion.
- Identity Verification — Compare two images to calculate confidence that they belong to the same person.
- FaceSet Management — Create and manage searchable face databases for large-scale matching.
- Body & Skeleton Analysis — Detect human bodies and skeletons to analyze posture and movement.
- Gesture Recognition — Identify specific hand gestures from image data.
How it works
- Subscribe to this server
- Enter your Face++ API Key and API Secret
- Start querying vision data through Claude, Cursor, or any MCP-compatible client
Who is this for?
- Security & Compliance — automate identity verification and KYC processes through natural language queries.
- UX Researchers — analyze user emotions and gestures during product testing directly from your AI-powered workspace.
- Developers — integrate a massive library of computer vision APIs into your AI-driven daily routines.
- Face++ Power Users — integrate your existing vision workflows into your AI-driven daily routines.

Frequently asked questions
How do I find my Face++ API Key and Secret?
Log in to the Face++ Console, go to [Dashboard] -> [API Key], and you will find your unique Key and Secret there. Ensure you have the necessary permissions enabled.
Can I analyze images from a local file?
This server currently supports analysis via image_url. To use local files, you should upload them to a public or private storage and provide the resulting URL to the tools.
What attributes can be returned during face detection?
Common attributes include gender, age, emotion, head pose, smile, face quality, and skin status. You can specify these in the return_attributes parameter of the detect_face tool.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
