How do I get an App ID?

You must register a developer account on the UnionPay International Developer portal. Once your business is verified, you can create an app to obtain credentials.

Does KYC card checking cost money?

Yes, depending on your contract with UnionPay, calls to identity verification and risk assessment endpoints may incur minor micro-transaction fees per successful hit.

Can I use RSA Certificates instead of App Secret?

This MCP wrapper abstracts away the complex RSA `.pfx` certificate signing by requiring standard API Key interaction, which is securely transformed in the agent execution runtime.

UnionPay Open Platform + Pydantic AI FAQ

Common questions about integrating UnionPay Open Platform 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 UnionPay Open Platform MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
