JWT & Base64 Decoder + Pydantic AI FAQ

Common questions about integrating JWT & Base64 Decoder 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 JWT & Base64 Decoder MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
