01 · Install A11y Check

Claude Code

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

Claude Desktop / Cursor / VS Code - add to config

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

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-07-14 - young repo, little track record yet

license AGPL-3.0 - declared in the repository

npm package @a11ychk/mcp - the @a11ychk scope differs from the repo owner (isaaceryn); confirm it's the project's official package

registry vendor namespace com.a11ychk - domain-verified with the official MCP registry
