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": {
    "accessibility-scanner": {
      "command": "npx",
      "args": [
        "-y",
        "accessibility-scanner-mcp"
      ],
      "env": {
        "CHROME_PATH": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add accessibility-scanner --env CHROME_PATH=your-value -- npx -y accessibility-scanner-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "accessibility-scanner": {
      "command": "npx",
      "args": [
        "-y",
        "accessibility-scanner-mcp"
      ],
      "env": {
        "CHROME_PATH": "your-value"
      }
    }
  }
}

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": {
    "accessibility-scanner": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "accessibility-scanner-mcp"
      ],
      "env": {
        "CHROME_PATH": "your-value"
      }
    }
  }
}

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 Accessibility Scanner MCP 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 5 months 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.

What can I use instead?

README from the maker

Open the README

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.

accessibility-scanner-mcp

An MCP server that lets an AI agent scan a web page for WCAG accessibility issues and get back findings it can act on. The agent calls one tool with a URL; it gets every violation grouped by severity, each with the exact element selector, the offending HTML, the specific failure, the WCAG success criterion, and a fix-guide link — plus the items that still need human review.

It runs the real axe-core engine in your local Chrome (via playwright-core), so nothing about the pages you scan leaves your machine. It scrolls the page first so lazy-loaded content is actually checked rather than silently skipped, and it resolves color contrast over CSS gradients, which most tools leave as "needs review."

Upgrading from 0.1.x? 0.2.0 sees more of each page and returns more findings for the same URL.

See CHANGELOG.md.

Part of accessibilityscanner.app.

Requirements

Node.js 18+
A Chromium-based browser: Chrome, Chromium or Edge, found automatically in that order. Set CHROME_PATH to point at a specific binary if you'd rather choose. A browser already installed by Playwright is used as a last resort; nothing is ever downloaded for you.

Or no browser at all

Set SCANNER_API_URL and the scan runs on accessibilityscanner.app instead of locally:

{ "env": { "SCANNER_API_URL": "https://accessibilityscanner.app" } }

No account or key needed — it uses the same public endpoints the website's own form uses. Useful in CI, in a container, or anywhere you can't install a browser. Hosted scans also carry suggested fix colours for contrast failures, which the local scanner doesn't compute yet.

⚠️ In this mode the URL you scan is sent to our server. The local path sends nothing anywhere, and stays the default — hosted mode is opt-in via that environment variable only.

Install

Add it to your MCP client's config. No global install needed — npx fetches it on first run.

Claude Desktop (claude_desktop_config.json), Cursor, Claude Code, or any MCP client:

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

If Chrome is not auto-detected, add an env block:

"mcpServers": { "accessibility-scanner": { "command": "npx", "args": ["-y", "accessibility-scanner-mcp"], "env": { "CHROME_PATH": "/usr/bin/google-chrome" } } } }

The tool

`scan_accessibility`

Input
`url` (string, required)	The http(s) URL to scan.

Returns a report grouped by severity. For each rule: the WCAG criterion, a fix-guide link, and per element the selector, HTML, and exact failure. Example flow with an agent:

You: Audit https://example.com for accessibility and fix what you can.

Agent: *(calls scan_accessibility)* → reads the findings → edits the code → re-scans.

Honest about limits

Automated testing covers the machine-checkable subset of WCAG (most of the issues on a typical page, but not all of it). Items that need human judgement are returned under "Needs manual review." It never claims a page is "compliant."
