The Problem

Playwright MCP sends **~14,000 tokens** for a content-heavy page like Hacker News. Most of that is noise. Your context window fills up. Your agent gets confused. You pay for it.

Leapfrog sends **~1,400 tokens**. Same page. Same information. Up to 10x less noise.

Savings range from 2-10x depending on page complexity. Content-heavy pages see the biggest wins. Dense forms see the smallest. The median across real-world sites is **~4-5x**.

Quick Start

npx leapfrog-mcp --doctor          # verify everything works
npx leapfrog-mcp --stealth-audit   # test all 19 stealth patches
npx leapfrog-mcp --config          # print MCP config to paste

Add to `~/.mcp.json` (Claude Code) or your editor's MCP config:

{
  "leapfrog": {
    "command": "npx",
    "args": ["-y", "leapfrog-mcp"],
    "env": {
      "LEAP_MAX_SESSIONS": "15",
      "LEAP_TILE": "true",
      "LEAP_HUD": "true",
      "LEAP_AUTO_CONSENT": "true"
    }
  }
}

Leapfrog uses `playwright-core` (15MB) instead of `playwright` (1.6GB) and does **not** bundle a browser. Either:

• Set LEAP_CHANNEL=chrome to use your installed Chrome/Chromium (recommended)
• Or run npx playwright-core install chromium to install the bundled Chromium binary
