sitemapkit

Research

Discover and extract sitemaps from any website using SitemapKit. Use this skill whenever the user wants to find pages on a website, get a list of URLs from a domain, audit a site's structure, crawl a sitemap, check what pages exist on a site, or do anything involving sitemaps or site URL discovery — even if they don't explicitly say "sitemap". Requires the sitemapkit MCP server configured with a valid SITEMAPKIT_API_KEY.

SitemapKit

Use the SitemapKit MCP tools to discover and extract URLs from any website's sitemaps.

Tools available

discover_sitemaps — finds all sitemap files for a domain (checks robots.txt, common paths, sitemap indexes). Use this first when you just want to know what sitemaps exist.
extract_sitemap — fetches all URLs from a specific sitemap URL. Use when the user gives you a direct sitemap URL.
full_crawl — discovers all sitemaps for a domain and returns every URL across all of them in one call. Use this when the user wants the complete list of pages on a site.

When to use which tool

User says	Use
"find sitemaps for X" / "does X have a sitemap?"	`discover_sitemaps`
"extract URLs from X/sitemap.xml"	`extract_sitemap`
"get all pages on X" / "crawl X" / "list all URLs on X"	`full_crawl`

Usage guidelines

Always pass a full URL including protocol: https://example.com
full_crawl and discover_sitemaps only use the domain — paths are ignored
extract_sitemap needs the exact sitemap URL, e.g. https://example.com/sitemap.xml
Default max_urls is 1000. If the user wants more, pass a higher value (up to plan limit)
If truncated: true appears in the result, tell the user there are more URLs and suggest increasing max_urls
Check meta.quota.remaining in the response — if it's low, warn the user proactively

Error handling

Error	What to tell the user
`Unauthorized`	API key is missing or invalid. Get one at https://app.sitemapkit.com/settings/api
`Monthly quota exceeded`	Plan limit reached. Upgrade at https://sitemapkit.com/pricing
`Rate limit exceeded`	Too many requests per minute. Wait and retry — the response includes a `retryAfter` timestamp

Example interactions

"What pages does stripe.com have?" → Call full_crawl with url: "https://stripe.com", present the URL list.

"Find all sitemaps for shopify.com" → Call discover_sitemaps with url: "https://shopify.com", list the sitemap URLs found and which sources they came from (robots.txt, common paths, etc.).

"Extract https://example.com/sitemap-posts.xml" → Call extract_sitemap with url: "https://example.com/sitemap-posts.xml", present the URLs with lastmod dates if available.

"How many pages does vercel.com have?" → Call full_crawl, report totalUrls and whether the result was truncated.
