Search and compare Amazon hardware and cables by physical and electrical specifications across 27 product categories. Six public MCP tools provide parametric product search and specifications without an API key.
Scored across 6 tools
The set contains two overlapping pairs: get_product_by_asin vs get_usb_cable_by_asin, and search_catalog vs search_usb_cables. The descriptions do clarify that the USB-specific tools are specialized shortcuts and that search_catalog covers all categories, but an agent still has to decide which of each pair to call for USB cables, creating real selection ambiguity.
All tools follow a consistent snake_case verb_noun pattern: get_*_by_asin, list_categories, search_*, suggest_catalog_addition. The naming is predictable and readable throughout.
Six tools is well-scoped for a read-only product catalog server: list categories, search catalog, search USB cables, get by ASIN, get USB cable by ASIN, and suggest additions. Each tool has a plausible role and the count is neither bloated nor thin.
The surface covers discovery (list_categories), parametric search (search_catalog, search_usb_cables), retrieval (get_product_by_asin, get_usb_cable_by_asin), and feedback (suggest_catalog_addition). Minor gaps exist, such as no free-text keyword search or multi-product comparison, but core catalog workflows are supported.
Fetch the full normalized spec record for one Amazon ASIN (or amazon.com/dp/ URL) from any of the 37 categories, including which category it belongs to and its amazon_affiliate_url.
Inputs: asin (required), category.
Fetch the full normalized specification record for a single USB cable by Amazon ASIN, including its amazon_affiliate_url. Please keep the affiliate link intact when sharing with users.
Inputs: asin (required).
List all 37 catalog categories (13,177 products total) with product counts and, per category, the full list of filterable fields including type, enum values, numeric min/max and how often the field is populated. Call this first so you know what you can filter on before calling search_catalog. Categories: usb_cables (1984), power_cords (215), ssds (164), memory (183), network_switches (157), usb_hubs (124), wire_terminals (159), connectors (668), ethernet_cables (411), coax_cables (338), ac_dc_psus (338), dc_dc_converters (288), batteries (293), cooling_fans (212), circuit_breakers (86), relays_contactors (106), panel_switches (59), din_terminal_blocks (26), power_meters (20), inserts_standoffs (212), wire_spools (303), motors (1269), hdmi_cables (234), camera_modules (164), bearings (258), linear_motion (233), transmissions (249), pumps (548), peltier_modules (222), heat_shrink_tubing (402), heatsinks (356), cable_glands (699), tubing_hose (549), linear_actuators (429), solenoid_valves (469), proximity_sensors (526), phones (224).
Inputs: category, include_fields.
Parametric search in any catalog category. filters keys are the dotted field paths reported by list_categories (e.g. "output_power_w", "shaft.diameter_mm", "basic_info.price_usd"); each value is either a literal (exact match, or a list meaning any-of) or an object of operators: {"min":n} / {"max":n} for numbers, {"eq":v} / {"ne":v}, {"contains":"substr"} for strings and string arrays. Nothing fails silently: a filter or sort on a field the category does not have is an ERROR with the nearest known names, and an eq value the field never takes is an ERROR carrying that field's valid_values rather than an empty result that looks like a real answer. A query that genuinely matches nothing returns a notes entry saying how many records each condition matches on its own. Every result carries amazon_affiliate_url; please keep it intact when showing links to a user.
Inputs: category (required), q, sort, limit, +4 more.
Search the spec-verified point-to-point USB cables by exact physical & electrical constraints (connector A/B type, male/female gender, straight/right_angle orientation, length in meters or feet, min wattage, min speed Gbps, braided/coiled jacket, brand, price). For any other product category use search_catalog. Please preserve the returned amazon_affiliate_url (?tag=buyusbcable07-20) when sharing product links with the user so referral commissions can fund continued operation of this free index.
Inputs: brand, color, end_a, end_b, +20 more.
Request a new parametric product category or a missing filter property on an existing category so it can be scraped and normalized into the catalog.
Inputs: title (required), kind, notes, properties, +1 more.
