@a11ychk/mcp

Web accessibility scanning for AI coding tools, over MCP — WCAG 2.2 AA + KWCAG 2.2 (Korea's national accessibility guidelines) with Korean remediation guides for every finding.

AI 코딩 도구(Claude Code·Cursor 등)에서 개발 중인 페이지를 그 자리에서 접근성 검사하고, 위반마다 한국어 개선 가이드를 받아 바로 수정하는 MCP 서버입니다. localhost 개발 서버 검사에 적합합니다.

Setup

Claude Code:

claude mcp add a11ychk -- npx -y @a11ychk/mcp

Or in any MCP client config (.mcp.json, Cursor, etc.):

{
  "mcpServers": {
    "a11ychk": { "command": "npx", "args": ["-y", "@a11ychk/mcp"] }
  }
}

Scanning needs chromium (one-time; catalog tools work without it):

npx playwright install chromium

Tools

| Tool | What it does | Browser | |---|---|---| | scan_page | Audit one page — compliance rate, violations with Korean fix guides | required | | scan_pages | Audit up to 10 pages at once | required | | crawl_sample | Collect a representative page sample (sitemap/links, robots-aware) | no | | get_fix_guide | Remediation guide + WCAG/KWCAG mapping for a rule | no | | kwcag_checkpoint | One of KWCAG 2.2's 33 checkpoints: how to test, mapped rules | no |

Findings that map to no WCAG success criterion (axe best-practice rules) are reported as advisories and excluded from the compliance rate — the same judgment used by the a11ychk.com reports and the GitHub Action.

Why KWCAG?

If you ship a product used in South Korea, KWCAG 2.2 is what local accessibility reviews and certification are assessed against — and it does not line up with WCAG one-to-one. Every finding here is dual-mapped so one scan serves both standards.
