AI agents call search_products to retrieve information from Kifly — Agentic Commerce & Payments 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_products 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 or browse Kifly's product catalog. Multilingual semantic search (100+ languages). Returns a JSON-LD ItemList with kifly:totalCatalogSize. When empty, kifly:emptyReason is 'empty_catalog' | 'no_matches_for_query' — on 'no_matches_for_query' tell the buyer nothing matched rather than guessing. Results carry kifly:relevanceScore [0–1]; a semantic similarity floor filters out irrelevant results automatically. Omit q to browse. Each result includes kifly:seller with store info and kifly:variantId. Pagination (browse only): when kifly:hasMore is true, pass kifly:nextCursor as cursor to fetch the next page. Seller filter: pass seller_handle to scope results to one seller. Category filter: free-text, case-insensitive (e.g. 'fashion'). Before checkout, call set_shipping_address.. It is categorised as a Read tool in the Kifly — Agentic Commerce & Payments MCP Server, which means it retrieves data without modifying state.
Register the Kifly — Agentic Commerce & Payments MCP server in PolicyLayer and add a rule for search_products: allow, deny, rate-limit, or require approval.

search_products 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_products 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_products. 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_products is provided by the Kifly — Agentic Commerce & Payments MCP server (https://kifly.io/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
