Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
作者提供的说明(英文原文)
How any SaaS pricing page changed over the years, from the Wayback Machine. No API keys.
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 …”。
打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json
{
"mcpServers": {
"pricing-time-machine": {
"command": "uvx",
"args": [
"pricing-time-machine-mcp"
]
}
}
}在终端中运行这条命令
claude mcp add pricing-time-machine -- uvx pricing-time-machine-mcp粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json
{
"mcpServers": {
"pricing-time-machine": {
"command": "uvx",
"args": [
"pricing-time-machine-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。

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。
它在你的电脑上运行。你的 AI 应用会在需要时启动它,数据不会经过作者的服务器(除非它自己调用在线服务)。
GitHub 仓库最后更新于–,最新版本(0.1.0)于38天前进入注册中心。
支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。你的电脑上还需要有 Python (uv)。

See how any SaaS pricing page changed over the years. An MCP server that reads archived copies of pricing pages from the Wayback Machine and pulls out the plans and prices, so Claude (or any MCP client) can tell you when a competitor raised prices, renamed plans or dropped a free tier.
No API keys. No scraping of live sites. One line to install.
You: How did Notion's pricing change since 2022?
Claude: [compare_pricing → notion.so/pricing, 2022-03 vs latest] • Personal Pro ($4/mo billed yearly) is gone; the cheapest paid plan is now Plus at $10 per member/month. • Team ($8/user/mo) became Business at $20 per member/month: 2.5×. • Free is still $0.
<sub>Summarized from real tool output: archived copies of 31 Mar 2022 and 7 Sep 2026.</sub>
| You want to know | Without it | With pricing-time-machine |
|---|---|---|
| When a competitor raised prices | Click through dozens of Wayback snapshots by hand | pricing_timeline lists price periods and every change |
| What their plans looked like in 2021 | Find a snapshot, read the page | pricing_at returns prices with plan names and billing hints |
| How a whole market moved | Days of spreadsheet work | compare_competitors puts 2-8 pricing pages side by side at any date |

C[Claude / MCP client] -->|tool call| S[pricing-time-machine-mcp] S --> I[Wayback CDX index: which months were archived] S --> W[Archived page closest to a date] W --> X[Extract prices: amount, currency, /mo /yr, per user, plan guess, context] X -->|compact table + page text around prices| C
The server does the deterministic part (finding snapshots, extracting prices, grouping periods). The model does the interpretation: which price belongs to which plan and what a change means. Archived pages never change, so they are cached on disk (~/.cache/pricing-time-machine).
Requires uv.
Claude Code
claude mcp add pricing-time-machine -- uvx pricing-time-machine-mcp
Claude Desktop / Cursor (claude_desktop_config.json / .cursor/mcp.json)
{
"mcpServers": { "pricing-time-machine": { "command": "uvx", "args": ["pricing-time-machine-mcp"] } } }
| Tool | What it does |
|---|---|
pricing_timeline | Reads N archived copies across the years, groups identical prices into periods, lists what was added/removed |
pricing_at | Prices on the page closest to a date, with plan guess, billing hints, context and the page text around them |
compare_pricing | One page at two dates: both price tables plus added/removed prices |
compare_competitors | 2–8 pricing pages side by side at the same date |
pricing_snapshots | Which months/years have an archived copy |
Prompts: pricing_history_report (one company, the full story with dates), competitor_pricing (a market then vs now).
Dates can be 2021, 2021-06, 2021-06-15 or latest; the closest archived copy is used and its date is always shown.
Open-source MCP servers that answer one market question each, with public data and no API keys.
| Server | Question it answers |
|---|---|
| review-miner-mcp | What do users hate about competitor apps and games? (App Store + Steam reviews) |
| pricing-time-machine-mcp (this one) | How did a SaaS pricing page change over the years? (Wayback Machine) |
| hn-hiring-trends-mcp | Which skills are tech companies hiring for, and which are rising? (HN Who is hiring) |
| model-price-radar-mcp | What does each LLM cost, and did it get cheaper? (OpenRouter + price history) |
| launch-detector-mcp | What is a company about to launch? (certificate transparency logs) |
