Fetch the full normalized spec record for one Amazon ASIN (or amazon.com/dp/<ASIN> URL) from any of the 27 categories, including which category it belongs to and its `amazon_affiliate_url`.
10-character Amazon ASIN (e.g. "B0CFZPSPBY") or full amazon.com/dp/... URL.
Optional hint; the ASIN is still looked up across every category if it is not there.

}List all 27 catalog categories (8,753 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).
| Argument | Type | Description |
|---|---|---|
| category | string | Restrict the answer to one category. |
| include_fields | boolean | Include the full field schema for each category (default true when `category` is given, false otherwise). |

}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.
| Argument | Type | Description |
|---|---|---|
| q | string | Free-text keyword search; all whitespace-separated tokens must appear somewhere in the record. |
| sort | string | Sort as "<field>:asc" or "<field>:desc" (nulls always last), or an alias: price_asc, price_desc, rating_desc, reviews_desc. Defaults to price_asc. |
| limit | number | Max results (default 15, max 250). |
| fields | array | Project each result down to these dotted field paths (asin and amazon_affiliate_url are always included). |
| filters | object | Field path -> literal, list of literals, or {eq|ne|min|max|contains} object. Example: {"output_power_w": {"min": 200}, "form_factor": "din_rail", "title": {"contains": "mean well"}}. |
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.
| Argument | Type | Description |
|---|---|---|
| brand | array | Filter by brand name(s), e.g. ["Anker", "UGREEN", "Cable Matters"]. |
| color | string | Color substring filter (e.g. "black", "white", "red"). |
| end_a | array | Connector A type(s). Valid values: USB-C-3.0, USB-A-3.0, USB-A-2.0, Lightning, USB-Micro-B-2.0, USB-Micro-B-3.0, USB-Mini-B, USB-B-2.0, USB-B-3.0 (or aliases like "USB-C", "USB-A", "Micro-USB", "Mini-USB", "Lightning"). |
| end_b | array | Connector B type(s). Valid values: USB-C-3.0, USB-A-3.0, USB-A-2.0, Lightning, USB-Micro-B-2.0, USB-Micro-B-3.0, USB-Mini-B, USB-B-2.0, USB-B-3.0. Orientation is symmetric (end_a↔end_b automatically matches reversed cables). |
| limit | number | Max results to return (default 15, max 100). |
| query | string | Free-text keyword search across title, brand, model, ASIN, certifications. |

}We read every tool's name, description and inputs the way the model will, looking for instructions hidden from you. A clean result means no warning signs, not a guarantee. Scanned Nov 11, 2026.
No readOnlyHint / destructiveHint annotations, so clients can't tell a read from a write without asking.
Fix: Add annotations to each tool, e.g. { readOnlyHint: true } for tools that only read.
