概览

AI 生成的概览

免费的免认证远程 MCP 服务器，可在 27 个类目、8,753 件经规范化的亚马逊硬件、线缆、电机、电源和轴承零件中做参数化搜索。

可以做什么
  • 列出 27 个类目及产品数量和可筛选字段结构
  • 在任意类目中按字段筛选、运算符、排序和字段选择进行参数化搜索
  • 按亚马逊 ASIN 或商品链接获取单个产品的完整规范化规格记录
  • 按接头类型、朝向、长度、功率、速率、外被和价格搜索点对点 USB 线缆
  • 提交新增产品类目或缺失筛选属性的请求
适用场景
适合为机器人、电子或物料清单（BOM）工作挑选现成零件，需要精确的物理与电气规格而非关键词搜索结果时。也适合原本直接抓取亚马逊商品页、却遇到拦截或内容被截断的助手。
运行要求
远程 streamable HTTP 端点；无需 API 密钥、账号或订阅。为仅支持 stdio 的客户端提供基于 npx（Node 18 及以上）或 Docker 的本地桥接。需要能访问该服务的网络。
安装前请注意
返回的商品带有亚马逊联盟链接，服务器要求助手在向用户分享时保留该链接，运营方由此获得推荐佣金。搜索和 ASIN 查询会发送给第三方服务。suggest_catalog_addition 工具会向运营方提交请求。目录规格属第三方数据，购买前应自行核实。

安装

在 SourceWeft 中

  1. 打开 控制台中的 BuyUSBCables Parametric Hardware & Cable Index，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

buyusbcables-mcp — Parametric Amazon Hardware & Cable Index for AI Agents

Free, zero-auth Model Context Protocol (MCP) server, REST JSON API, and AgentSkill over 8,753 LLM-verified Amazon hardware, cable, motor, bearing, power supply, connector, switch, camera, and wiring products across 27 parametric engineering categories (buyusbcables.com).

Why this exists

Coding, robotics, and BOM-sourcing agents consistently hit walls when looking up off-the-shelf Amazon parts:

  1. Direct WebFetch / curl on amazon.com/dp/<ASIN> fails: Amazon returns HTTP 503, serves a stripped FallbackDetailPage, or sends ~1.42 MB of navigation JavaScript before the product specs — truncating standard agent fetch tools at <title>.
  2. Amazon PA-API 5.0 has a 3-sales catch-22: New developer accounts cannot call PA-API until they have already generated qualifying referral sales, and accounts with <3 sales in 180 days are closed.
  3. Raw keyword search lies about physics: Broad Amazon searches bury right-angle or silicone cables, mix metric and imperial dimensions, and include contradictory title spam (e.g., 30A plugs on 14 AWG wire or mixed assortment kits).

buyusbcables.com normalizes every listing into strict per-category physical and electrical schemas, rejects contradictory specs and mixed kits, and fails loudly with valid field/enum suggestions instead of returning silent empty results.

Quickstart

Option 1: Remote Streamable HTTP MCP (Recommended — Zero Install)

Claude Code:

bash
claude mcp add --transport http buyusbcables https://www.buyusbcables.com/api/mcp

Cursor / Windsurf / OpenCode / Codex (mcpServers):

json
{  "mcpServers": {    "buyusbcables": {      "url": "https://www.buyusbcables.com/api/mcp"    }  }}

Option 2: Local stdio Bridge (npx / Node >= 18 / Docker)

For stdio-only MCP clients (e.g. Claude Desktop command configs):

json
{  "mcpServers": {    "buyusbcables": {      "command": "npx",      "args": ["-y", "github:dwiel/buyusbcables-mcp"]    }  }}

Option 3: Zero-Auth REST API & <8 KB HTML Datasheets

bash
# List all 27 categories + counts (add ?include=fields for full schemas)curl -s "https://www.buyusbcables.com/api/catalog"
# Inspect filterable fields, valid enums, and min/max numeric rangescurl -s "https://www.buyusbcables.com/api/catalog/motors?schema=1"
# Filter 24V DIN-rail AC-DC power supplies >= 200W, cheapest firstcurl -s "https://www.buyusbcables.com/api/catalog/ac_dc_psus?output_power_w.min=200&output_voltage_dc_v=24&sort=price_asc&limit=5"
# Filter right-angle USB-C cables >= 100W and >= 10 Gbpscurl -s "https://www.buyusbcables.com/api/cables?end_a=USB-C&end_b=USB-C&end_a_orientation=right_angle&min_wattage=100&min_speed_gbps=10"
# Lookup a single Amazon ASIN (JSON or clean WebFetch-friendly HTML datasheet)curl -s "https://www.buyusbcables.com/api/product/B0B38GHRH8"curl -s "https://www.buyusbcables.com/p/B0B38GHRH8"

list_categories

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).

search_catalog

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.

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`.

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.
