FAQ

Frequently asked questions

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.

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.
