How do I find my Youzan Client ID and Secret?

Log in to the [Youzan Cloud Console](https://console.youzanyun.com/), create an application, and you will find your Client ID (App Key) and Client Secret in the app settings.

Where is my Shop ID (kdt_id)?

Your Shop ID (kdt_id) can be found in the bottom left corner of your Youzan store administration backend.

Can I check stock levels for specific product variants?

Yes. Use the `get_inventory` tool with the product's item ID. It will return a list of all SKUs (variants) along with their current stock levels and pricing.

Youzan / 有赞 + Pydantic AI FAQ

Common questions about integrating Youzan / 有赞 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 Youzan / 有赞 MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
