Broken Link Scanner

Find every broken link on a page. No signup required.

Prerequisites

• Playwright MCP (comes with Claude Code)

Trigger

• "Find broken links on https://..."
• "Check for 404s on my site"
• "Scan links on this page"

Workflow

1. Navigate to the URL using mcp__playwright__browser_navigate
2. Extract all links using mcp__playwright__browser_evaluate:

() => {
  return Array.from(document.querySelectorAll('a[href]')).map(a => ({
    text: a.textContent.trim().substring(0, 50),
    href: a.href,
    isExternal: a.host !== location.host
  }));
}

1. For each link (up to 50), check status:

   • Internal links: navigate and check for error pages
   • External links: note them but don't crawl (avoid rate limits)
   • Flag: 404, 500, redirect chains, empty href, javascript:void

2. Output:

## Broken Link Report: [URL]

**Scanned: 34 links** (28 internal, 6 external)
