Parameters from the server's own tool schema.
The tool performs a search query against a public food database, returning product information. This is a typical Read operation: it retrieves data, has no side effects, and cannot modify, delete, or execute external operations. Blast radius is minimal—an agent using this tool can only discover food product information, which is already public.
From the tool's definition Tool description states 'Search for food products on Open Food Facts' — search is a read-only operation that retrieves data without side effects.
