What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Web & browsers

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

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

Run this in your terminal

claude mcp add pxtree -- npx -y pxtree mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

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

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "pxtree": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "pxtree",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is pxtree safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 43 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

pxtree

Loads a webpage in headless Chromium and prints what actually rendered as a compact text tree, so an AI coding agent can check a layout without a screenshot.

A dev server page with a row of three cards, a row of three plans, a list of steps, a row of stats, an article, a form, a column of prices and a row of tiles:

The first line is the facts line: viewport, color scheme, device pixel ratio, direction, scroll position out of the maximum, document size, and painted to, the lowest painted pixel. since last run compares with the previous run of the same URL and settings, or of the same --diff-key name. That history lives in ~/.cache/pxtree, never in your project, and --no-diff skips it.

The ul.cards line says the "Choose" buttons in the three cards have tops from 64 px to 136 px below the top of their card. The li.plan.featured "Lifetime" line says that plan is 212x56 at x 432 in its row, 12 px wider than the width its siblings share. Findings are measurements with a threshold, never verdicts. The agent decides from the code whether they are intended.

Why not a screenshot

It gives numbers in CSS px, not pixels the model has to estimate.
The agent reads it in one pass, as text, with the findings listed on top.
One call covers several viewports and color schemes.

Install

pxtree drives Playwright's Chromium. Install it once, about 150 MB:

npx -y playwright@1.63.0 install chromium

pxtree itself downloads nothing and never edits your project. --channel chrome uses an installed Chrome instead. Needs Node 20 or newer.
