How do I find my Face++ API Key and Secret?

Log in to the [Face++ Console](https://console.faceplusplus.com.cn/), 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.

About 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.

Pydantic AI validates every Face++ / Megvii tool response against typed schemas, catching data inconsistencies at build time. Connect 10 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.

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.

The Face++ / Megvii MCP Server exposes 10 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Face++ / Megvii + Pydantic AI FAQ

Common questions about integrating Face++ / Megvii MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your Face++ / Megvii MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
