Tools

check_links

Check all links on a single webpage.

Example prompt:

Check all links on https://example.com for broken URLs

Output: JSON with status, statusText, redirectTo, responseTime, and location for every link found.

deep_scan

Recursively crawl internal pages and check all discovered links.

Example prompt:

Deep scan https://example.com with depth 2 to find all broken links

Parameters:

  • url — Starting URL
  • depth — Crawl depth 1-3 (free: max 1)

check_sitemap

Parse a sitemap.xml and check every listed URL.

Example prompt:

Check all URLs in https://example.com/sitemap.xml

Output: Status of every URL in the sitemap, with broken links and timeouts highlighted.

How It Works

  1. Fetches the target page and extracts all <a href> links
  2. Checks each link using HTTP HEAD (fast), falls back to GET if HEAD is rejected
  3. Parallel batch requests (10 at a time) with 10s timeout and 1 retry
  4. Reports: broken (4xx/5xx), redirects (301/302), timeouts, and healthy links
