Pricing Time Machine tools (5)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • compare_competitors

    Prices of 2-8 competitors' pricing pages side by side, as archived closest to the same date.

  • compare_pricing

    Compare one pricing page at two dates: prices and plans on each, plus what was added/removed.

  • pricing_at

    Prices on a pricing page as archived closest to a date: each price with its plan guess, billing hints and context, plus the page text around the prices so you can read the plans.

  • pricing_snapshots

    List the dates the Wayback Machine archived a page (one per month or year). Use it to see how far back history goes and to pick dates for pricing_at.

  • pricing_timeline

    How a pricing page's prices changed over the years. Reads `points` archived copies spread across the range, groups identical price sets into periods and lists what was added/removed.

What the publisher says

From the Pricing Time Machine repository's README, as published. We do not edit it. Read it on GitHub

pricing-time-machine-mcp

<!-- mcp-name: io.github.alialtunar/pricing-time-machine-mcp -->

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.

Summarized from real tool output: archived copies of 31 Mar 2022 and 7 Sep 2026.

Why

How it works

flowchart LR
    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).

Install

Requires uv.

Claude Code

claude mcp add pricing-time-machine -- uvx pricing-time-machine-mcp

Claude Desktop / Cursor (claudedesktopconfig.json / .cursor/mcp.json)

{
  "mcpServers": {
    "pricing-time-machine": {
      "command": "uvx",
      "args": ["pricing-time-machine-mcp"]
    }
  }
}

Tools

Prompts: pricinghistoryreport (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.

Try these

  • "How did Slack's pricing change since 2016? Show every price increase in %."
  • "Compare the pricing of Notion, Coda and ClickUp today and in 2021."
  • "What did Figma charge for Professional in 2019?"
  • "Run pricinghistoryreport for linear.app/pricing."
