Frequently asked questions
Which models can I use?
Any model available on your API key: GPT-4o, GPT-4o-mini, GPT-4-turbo, o1, o3 — use list_models to see all.
Can I generate images?
Yes! Use generate_image with a text prompt. Supports 1024x1024, 1792x1024, and 1024x1792 sizes.
How does content moderation work?
The moderate_content tool analyzes text against OpenAI's content policy, flagging categories like hate, violence, and self-harm with confidence scores.
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 OpenAI MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
