Frequently asked questions
Can I filter products by a specific category like 'T-shirts'?
Yes! Use the list_products tool and provide the category_id. The agent will return only the products belonging to that specific Printful category.
How do I get the exact pricing and stock for a specific size and color?
You should use the get_variant tool with the specific Variant ID. This provides the most granular data including price, stock availability, and specific attributes.
Does this server provide measurements for the products?
Yes, the get_product_sizes tool returns the complete size guide for a product ID, including measurements in both imperial (inches) and metric (cm) units.
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 Printful MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
