Preview what a product will look like with an optional design. With no design, shows all variants and pricing. With a design URL or design_id, shows a text description of the final product ready for ordering. Does not create an order or charge any fees.
AI agents call preview_product to retrieve information from OpenPrints MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and displays product/design preview information. It explicitly states it does not create orders or charge fees, making it a pure read/query operation with minimal blast radius.
