AI agents call search_catalog to retrieve information from Curie Commerce without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though search_catalog only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Search the store catalog by name, brand, style, color, or keywords. This is the UCP/Shopify-canonical catalog-search tool (Shopify Storefront MCP's search_catalog, formerly search_shop_catalog); search_products is a deprecated alias of this tool. Returns matching products with images, prices, and 3D model availability. Use max_price / min_price for structured price filters — natural-language constraints like 'under $150' embedded in the query are also post-clamped server-side, but passing the structured arg is preferred (matches Shopify UCP filters.price.min/max). Returns structured product items suitable for inline gallery rendering. Recommended visualization: a horizontal scrolling React Artifact with product cards showing image, uppercase brand, title, price, and a small "3D" pill when has_3d_model is true. Use _meta.curie.brand.palette.brand_color for the accent color and tap-to-view as the primary action.. It is categorised as a Read tool in the Curie Commerce MCP Server, which means it retrieves data without modifying state.
Register the Curie Commerce MCP server in PolicyLayer and add a rule for search_catalog: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Curie Commerce. Nothing to install.
search_catalog is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_catalog rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for search_catalog. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
search_catalog is provided by the Curie Commerce MCP server (https://chat.curie.app/api/mcp/global). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
