PopNx MCP 的三大支柱

这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。

它能帮你做什么

我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。

安装

选择你使用的 AI 应用,然后复制设置。

安装之前

你需要

  • 在云端运行无需安装任何东西,通过互联网连接
  • npm已安装 Node.js(用于 npx 命令)

你用的是哪个应用?

在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。

适用于网页版、桌面版和手机版 Claude:

  1. 打开 Settings → Connectors
  2. 点击 Add custom connector
  3. 粘贴下面的地址,然后点击 Add
  4. 如果要求登录,请登录作者的服务
SettingsConnectors1+ Add2https://…3
https://edc4me.com/mcp

或者在你的电脑上运行

打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json

{
  "mcpServers": {
    "drop-beacon": {
      "command": "npx",
      "args": [
        "-y",
        "drop-beacon-mcp"
      ]
    }
  }
}

在终端中运行这条命令

claude mcp add --transport http drop-beacon https://edc4me.com/mcp

或者在你的电脑上运行

claude mcp add drop-beacon -- npx -y drop-beacon-mcp

在 Cursor 中打开

或者自己复制设置

粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json

{
  "mcpServers": {
    "drop-beacon": {
      "url": "https://edc4me.com/mcp"
    }
  }
}

或者在你的电脑上运行

在 Cursor 中打开

    }
  }
}

浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

在 VS Code 中打开

或者自己复制设置

粘贴到项目中的 .vscode/mcp.json

{
  "servers": {
    "drop-beacon": {

  • search_products

    Search Drop Beacon's catalog of 150,000+ everyday-carry products (knives, flashlights, fidget sliders and coins, pens, multitools). Returns matching products with brand, the catalog price and the edc4me.com page; models and configurations (steel, color) are separate products. Use

  • find_offers

    For one product, list the retailers that currently have it in stock, with price, configuration (blade steel, color, finish), when Drop Beacon last checked, any coupon, and a tracked buy link. If a name matches several models, the reply says so and lists other_matches. Prices are

  • deal_check

    Compare a product's lowest current in-stock price with the range Drop Beacon has observed (90-day low, all-time low, high, how long it has been watched) and return a plain verdict with a confidence level. Summary only; it does not return the full price history.

  • top_deals

    Live markdowns across the EDC products Drop Beacon tracks: in-stock items priced at least 10% below the seller's own compare-at ("was") price, checked in the last 3 days. Each result has the price, the was-price, percent and dollars off, the lowest price Drop Beacon itself has re

  • upcoming

    What's new in EDC right now: in-stock products Drop Beacon first saw in the last 7 days, plus Drop Beacon's live giveaways (free to enter) with draw dates and entry links.

  • get_brand_info

    A brand's Drop Beacon profile: page link, official website, whether it is a maker or a retailer, its in-stock product count and any public discount code.

常见问题

Drop Beacon 安全吗?

它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。

它需要哪些密钥或代码?

注册中心没有列出必需的密钥,不过有些服务器会在首次使用时要求你登录。

它在我的电脑上运行还是在云端?

两种方式都可以:安装在你的电脑上,或者连接云端版本。

它还在维护吗?

GitHub 仓库最后更新于–,最新版本(1.1.0)于前天进入注册中心。

哪些应用可以使用它?

支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

有什么可以替代它?

Drop Beacon MCP

Read-only EDC product discovery through Drop Beacon's public HTTPS catalog API. No database password, DATABASE_URL, or API key is required.

Remote server (no install)

Drop Beacon also runs a hosted, read-only MCP server at `https://edc4me.com/mcp` (Streamable HTTP, no key). Add it as a custom connector in Claude or ChatGPT, or point any MCP client at the URL. Its tools: search_products, find_offers (live in-stock prices across retailers with buy links), deal_check (today's price against the range Drop Beacon has observed), top_deals (the biggest live markdowns, with a was-price check), upcoming (new drops and free giveaways) and get_brand_info.

Install (local stdio package)

Requires Node.js 20 or newer. Configure your MCP client:

{

"mcpServers": { "drop-beacon": { "command": "npx", "args": ["-y", "drop-beacon-mcp@0.3.0"] } } }

Tools

ToolPublic data returned
search_productsUp to 25 currently available catalog matches
get_latest_dropsRecent in-stock listings first seen within seven days
get_brand_infoPublic brand profile and available-product count
check_availabilityUp to 10 matching available listings

Categories: knife, fidget, flashlight, pen, wallet, multi_tool, patch, other. Search arguments accept up to 120 characters. Results are catalog snapshots, not guarantees of current retailer stock. Compare the exact material, configuration and condition on the linked product page. No match does not mean unavailable everywhere. First seen means discovered by Drop Beacon, not released by the manufacturer.

Migration from 0.2.x

Remove DATABASE_URL and API_KEY from client and hosted-service settings. Upgrade any cached installation to 0.3.0 or newer. If a real database password was ever shared, revoke it with the database provider; editing a listing alone cannot revoke access.

Direct SQL access, arbitrary URLs, private records, and internal market analytics are not supported. get_market_trends and get_price_comparison have been retired from this public MCP; use the market pages and product comparison on the website. The old optional API_KEY gate and legacy SSE endpoints are removed. Do not send credentials as tool arguments.

Security boundary

The package has no database driver and only performs credential-free GET requests to https://edc4me.com/api/drops and /api/brands. Explicit output allowlists prevent new upstream fields from silently becoming MCP output. Requests reject redirects, time out after 15 seconds, cap response bodies at 2 MB, and return generic errors without upstream response bodies. Tool arguments cannot override the origin, endpoint, HTTP method, or headers.

The process allows 60 tool calls per minute, shared across clients and reset on restart; this is a best-effort local limit, not a distributed quota. The public API also applies its own edge protections. A 429 response asks the client to wait, never to supply database access.

Stdio is the default. Optional stateless HTTP uses PORT, binds to loopback by default, and serves POST /mcp plus GET /health. Hosted services can explicitly set HOST=0.0.0.0. Browser origins other than https://edc4me.com are rejected, request bodies are limited to 64 KB, and batched requests are rejected. No customer-specific authentication is needed because only public catalog data is available.

Development

npm ci && npm test

npm run security:scan scans tracked files, including documentation and environment examples, without printing secret values. See SECURITY.md for limitations and local hook setup.
