What the publisher says

From the OverlayQA repository's README, as published. We do not edit it. Read it on GitHub

OverlayQA MCP

OverlayQA MCP is a Model Context Protocol server that gives your AI coding agent accessibility and design-QA superpowers. Ask Claude Code, Cursor, or Windsurf to audit any URL for WCAG and color-contrast issues, then read, assign, discuss, label and resolve issues in your OverlayQA projects without leaving your editor.

You:   Scan staging.acme.com for accessibility issues, then open issues for the criticals.
Agent: scan_accessibility → 7 violations (2 critical, 3 high), score 71/100.
       scan_and_create_issues → created 2 issues in "Acme Web":
       - Buttons missing accessible names (WCAG 4.1.2): critical
       - Insufficient text contrast on .cta (WCAG 1.4.3): high
You:   List the open criticals.
Agent: list_issues(status=open, severity=critical) → 2 issues.

Install

One click:

  • Install in Cursor
  • Install in VS Code

Or add it to your editor's MCP config manually:

Claude Code (.mcp.json in your project root) / Cursor (~/.cursor/mcp.json) / Windsurf (~/.codeium/windsurf/mcp_config.json):

{
  "mcpServers": {
    "overlayqa": { "command": "npx", "args": ["@overlayqa/mcp@latest"] }
  }
}

Any MCP-compatible client works the same way. On first run a browser tab opens to connect your OverlayQA account (free, no card): pick the workspace, allow access, and the connection lasts 30 days. Credentials cache at ~/.overlayqa/auth.json; the access token is short-lived and refreshes in the background. Disconnect an editor at any time from Connected AI apps in the dashboard (app.overlayqa.com/mcp/connect).
