How do I install the accessibility mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `CHROME_PATH` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Accessibility MCP Server?

Scan any URL for WCAG accessibility issues (axe-core) and get per-element fixes for an AI agent.

What you get

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.

Configuration and credentials

Node.js 18+ - Google Chrome installed (or set the CHROME_PATH environment variable to a Chromium binary)
