Frequently asked questions
How do I find my Stripe Secret Key?
Log in to your Stripe dashboard, navigate to Developers > API keys, and you will find your Secret Key (starting with sk_live_ or sk_test_) there.
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 Stripe Legacy MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
