}Look up multiple products or variants by identifier. Use this tool to resolve multiple product/variant IDs in a single request. Supports: - Product IDs (gid://shopify/Product/...): Returns product with match: "featured" - Variant IDs (gid://shopify/ProductVariant/...): Returns parent product with the exact variant Results are grouped by product. Each variant includes an inputs array showing which request ID resolved to it and whether the match was exact or featured. In versions that require input correlations, only matched variants are returned.

Convert to major units before quoting a price to a buyer (divide by 100 for two-decimal currencies such as USD and EUR; zero-decimal currencies such as JPY are already whole units). Maximum 10 IDs per request.

}Search for products from the online store, hosted on Shopify. This tool can be used to search for products using natural language queries, specific filter criteria, or both. At least one of query or filters must be provided. Results are paginated, with initial results limited to improve experience. Use the pagination.cursor from the response to fetch additional pages when users request more results. Response conforms to the UCP catalog search capability (dev.ucp.shopping.catalog.search). Prices in the response are integers in the currency's ISO 4217 minor units, paired with a currency code: {"amount": 600, "currency": "USD"} is $6.00 and {"amount": 2500, "currency": "USD"} is $25.00. Convert to major units before quoting a price to a buyer (divide by 100 for two-decimal currencies such as USD and EUR; zero-decimal currencies such as JPY are already whole units).

}We read every tool's name, description and inputs the way the model will, looking for instructions hidden from you. A clean result means no warning signs, not a guarantee. Scanned Oct 31, 2026.
Takes a password, API key or token as an argument, so the secret passes through the model's context and chat logs.
Fix: Read credentials from the server's own configuration (environment, OAuth) instead of a tool argument.
No readOnlyHint / destructiveHint annotations, so clients can't tell a read from a write without asking.
Fix: Add annotations to each tool, e.g. { readOnlyHint: true } for tools that only read.
