How do I find my Aliyun AccessKey ID and Secret?

Log in to the [Alibaba Cloud Console](https://usercenter.console.aliyun.com/), navigate to [AccessKey Management] to find or create your unique ID and Secret.

What is the 'VerifyParam'?

The VerifyParam is a JSON string or token generated by the Aliyun CAPTCHA frontend component after a user successfully completes the challenge. It must be sent to this server for server-side validation.

Which regions are supported for the CAPTCHA API?

This server defaults to `cn-hangzhou`, but Aliyun CAPTCHA 2.0 is also available in `cn-shanghai`, `cn-beijing`, and `ap-southeast-1` (Singapore) for global applications.

Aliyun CAPTCHA / 阿里云验证码 + Pydantic AI FAQ

Common questions about integrating Aliyun CAPTCHA / 阿里云验证码 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 Aliyun CAPTCHA / 阿里云验证码 MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
