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。
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。
选择你使用的 AI 应用,然后复制设置。
你需要
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:
https://api.thrifle.com/api/mcp在终端中运行这条命令
claude mcp add --transport http thrifle https://api.thrifle.com/api/mcp粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json
{
"mcpServers": {
"thrifle": {
"url": "https://api.thrifle.com/api/mcp"
}
}
}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。

与注册中心里这个分类中所有活跃的服务器比较。只有当发布者拥有该仓库时,星标数才计入。
它在 1 项适用的基础检查中通过了 1 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。
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。
它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。
GitHub 仓库最后更新于–,最新版本(1.0.0)于2个月前进入注册中心。
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。

The data behind these tools: a return-policy database covering 2,250 US retailers with an A+–D− grade computed from the policy's own terms, price-match and price-adjustment policies, military/student discount programmes, birthday offers, cancellation guides, a curated deal feed, a credit-card database built from issuer pricing pages, and price history for hundreds of thousands of Amazon products. All of it is editor-verified and every record carries a last_verified date.
Claude.ai / Claude Desktop (every plan; Free allows one custom connector) Settings → Connectors → Add custom connector → paste the URL → leave authentication empty.
Claude Code
claude mcp add --transport http thrifle https://api.thrifle.com/api/mcp
ChatGPT — Settings → Apps & Connectors → Create (developer mode) → paste the URL, no authentication.
Cursor — click the badge above, or add to ~/.cursor/mcp.json:
{ "mcpServers": { "thrifle": { "url": "https://api.thrifle.com/api/mcp" } } }
VS Code — click the badge above, or code --add-mcp '{"name":"thrifle","type":"http","url":"https://api.thrifle.com/api/mcp"}'.
Perplexity (+ Custom connector → Remote), Grok (grok.com/connectors → Custom), Mistral Le Chat (Connectors → Custom MCP Connector), Gemini CLI (httpUrl under mcpServers), Gemini Enterprise (Manage team → Connected apps → Add MCP Server) all accept the same URL.
Claude Code plugin — this repo is also a Claude Code plugin (.claude-plugin/plugin.json, .mcp.json, and a thrifle-shopping skill that teaches the model which tool answers which question).

This is the same code that serves api.thrifle.com/api/mcp. THRIFLE_API_BASE points it at a different API base; MCP_RATE_PER_MIN / MCP_RATE_PER_DAY set the per-IP limits; MCP_API_KEYS (comma-separated) lists keys that bypass them via Authorization: Bearer.
McpServer + transport per request, JSON responses, no sessions — nothing to resume, nothing shared between callers, nothing for a CDN to buffer. GET on the endpoint returns a human-readable discovery document.src/api-client.js is a 60-line loopback fetch.src/shape.js turns each API response into the facts plus the canonical thrifle.com url and a cite block, and drops internal fields. Pure functions, all covered by fixtures.readOnlyHint: true; the catalogue in src/tools.js has no write path.Free for assistants answering a person's question: 60 calls a minute and 1,500 a day per address. Bulk or commercial use is licensed — see thrifle.com/data-licensing; a licence comes with a key that lifts the limits. Deal buy_url values are thrifle.com redirects and may be affiliate links.
