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": {
    "visualdiff": {
      "command": "npx",
      "args": [
        "-y",
        "@reneturcios/visualdiff",
        "mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add visualdiff -- npx -y @reneturcios/visualdiff mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "visualdiff": {
      "command": "npx",
      "args": [
        "-y",
        "@reneturcios/visualdiff",
        "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": {
    "visualdiff": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@reneturcios/visualdiff",

      ]
    }
  }
}

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 Visualdiff 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 (0.1.0) reached the registry 5 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, Docker on your computer.

What can I use instead?

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

visualdiff

visualdiff wraps the SnapDiff visual-testing API: verify that a UI change matches what you meant to do, diff two pages (or a page against a stored baseline), capture a screenshot of any URL, and render raw HTML/CSS straight to an image. One binary serves a command-line interface and a stdio MCP server.

An API key is required. Set SNAPDIFF_API_KEY to a key from the SnapDiff dashboard; calls fail before any request is made when it is missing. The API base URL can be overridden with SNAPDIFF_API_URL; when it is not set, calls go to https://api.snapdiff.ai/v1.

Install

npx @reneturcios/visualdiff screenshot https://example.com

Or run the container image:

docker run -i -e SNAPDIFF_API_KEY=sk_live_... ghcr.io/cloudcorprecords/visualdiff

The container defaults to the MCP server (see below). Pass CLI arguments to use it as a CLI instead.

CLI

export SNAPDIFF_API_KEY=sk_live_...

visualdiff verify myproj pricing https://staging.example.com/pricing "added a yearly billing toggle" visualdiff compare https://staging.example.com --before https://www.example.com visualdiff compare http://localhost:3000 --project myproj --page-name homepage visualdiff screenshot https://example.com --width 800 --full-page visualdiff html-to-image " Hello " --css "h1 { color: navy; }" --width 1200 --height 630

visualdiff --version

Commands print the upstream JSON payload. Exit codes: 0 on success, 1 when a call fails (including a missing API key or an upstream API error), 2 for usage errors.

MCP server

One bin serves both faces. The mcp subcommand starts a stdio MCP server:

npx -y @reneturcios/visualdiff mcp

MCP client configuration:

"mcpServers": { "visualdiff": { "command": "npx", "args": ["-y", "@reneturcios/visualdiff", "mcp"], "env": { "SNAPDIFF_API_KEY": "sk_live_..." } } } }

Tools

Tool	Input	What it returns
`snapdiff_verify_ui_change`	`project`, `page_name`, `after`, `intent` (all required); optional `intent_regions`, `branch`, `threshold`, `match_tolerance_percent`, `ignore_selectors`, `full_page`	A verdict (`pass`, `expected_change_detected`, `unexpected_regression`, `no_change_detected`, or `needs_human_review`), a `next_action`, and a `review_url`. Requires a project with a stored page baseline.
`snapdiff_compare_pages`	`after` (required); plus `before`, or `project` + `page_name` for baseline mode; optional `branch`, `threshold`, `ignore_selectors`, `full_page`	A diff percentage plus a highlighted diff image.
`snapdiff_capture_screenshot`	`url` (required); optional `full_page`, `dark_mode`, `selector`, `width`	A screenshot of the page.
`snapdiff_html_to_image`	`html` (required); optional `css`, `width`, `height`	The rendered image (OG cards, social images, email headers).

Each tool is sent as a POST to a per-tool endpoint under the base URL with the API key as a Bearer token. Optional arguments that are not supplied are omitted from the request body entirely.
