AI agents call search_shop_catalog to retrieve information from SFR Store 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_shop_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 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. Best practices: - Searches return available_filters which can be used for refined follow-up searches - When filtering, use ONLY the filters from available_filters in follow-up searches - For specific filter searches (category, variant option, product type, etc.), use simple terms without the filter name (e.g., "red" not "red color") - For filter-specific searches (e.g., "find burton in snowboards" or "show me all available products in gray / green color"), use a two-step approach: 1. Perform a normal search to discover available filters 2. If relevant filters are returned, do a second search using the proper filter (productType, category, variantOption, etc.) with just the specific search term - Results are paginated, with initial results limited to improve experience - Use the after parameter with endCursor to fetch additional pages when users request more results The response includes product details, available variants, filter options, and pagination info.. It is categorised as a Read tool in the SFR Store MCP Server, which means it retrieves data without modifying state.

Yes. Add a rate_limit block to the search_shop_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_shop_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.
