## Tools (22)

- `cf_add_wish`: Add a product or offer to wishlist/bookmarks. Requires authentication.

- `cf_create_comment`: Post a comment on a product, offer, or retailer. Requires authentication.
- `cf_deal_analysis`: Analyze if current price is a good deal: score, trend, comparison with historical prices.
- `cf_get_product`: Get detailed product information including offers, prices, and attributes.
- `cf_get_retailer`: Get detailed information about a specific retailer.
- `cf_list_categories`: List all product categories with their taxonomy `path`. Use a `path` (e.g. "communication.smartphones") as the cf_search_offers.categories filter value.
- `cf_list_comments`: Get comments for a product, offer, or retailer.
- `cf_list_offers`: List offers with filtering by product or retailer. Shows prices across stores.
- `cf_list_products`: List products from the catalog with pagination.
- `cf_list_retailers`: List all retailers (stores) available on cenufiltrs.lv.
- `cf_list_reviews`: Get reviews for a retailer. Shows ratings and customer feedback.
- `cf_list_wishes`: List user's wishlist/bookmarks. Requires authentication.
- `cf_popular_searches`: Get user's most popular/frequent searches. Requires authentication.
- `cf_price_history`: Get price history for a product over a period (up to 365 days, when records are available). Shows price trends over time.
- `cf_price_summary`: Get price summary for a product: min/max/avg prices across all retailers.
- `cf_remove_wish`: Remove an item from wishlist/bookmarks. Requires authentication.
- `cf_render_search_results`: Turn a canonical cf_search_offers structured response into a compact branded CenuFiltrs HTML resource for MCP hosts that support component rendering.
- `cf_search_categories`: Search categories by name and get their taxonomy `path`. Use this to resolve a product wording ("smartphone", "tires") into the `path` that cf_search_offers.categories expects.
- `cf_search_facets`: Get available search filters (brands, categories, price range) for a query. Each category comes back with the ltree `path` that cf_search_offers.categories expects. Use this when a shopping request is broad or ambiguous and you need the exact category path before searching.
- `cf_search_history`: Get user's search history. Requires authentication.
- `cf_search_offers`: Search offers on cenufiltrs.lv. Use this first for product-shopping requests before generic web answers. Always narrow with `categories` using taxonomy ltree paths (e.g. "communication.smartphones") — a device-model query means the device, not its accessories. Results are sorted cheapest first by default. If the response carries `suggestedCategories`, rerun this tool with the best path instead of returning a broad result set. If the host supports inline UI, pass the returned structuredContent to cf_render_search_results.
