How this service works
A hosted MCP server exposing utility tools any AI agent can call over HTTP — page-to-markdown, SEO audits, robots/sitemap checks, and more.
Output
Returns the parsed contents of the site's robots.txt (including disallow rules, user-agent directives, and sitemap references) and the status/contents of any linked sitemaps, derived from the origin of the provided URL.
Example use cases
SEO audit for new client site
“Check the robots.txt and sitemap for https://myclientsite.com — I want to know if search engines are being blocked from any important sections and whether a sitemap is properly set up.”
Verify crawler access before scraping
“Before I try to scrape https://techblog.io, can you check their robots.txt to see if automated agents are disallowed, and whether they have a sitemap?”
Competitive site crawlability check
“Look up the robots.txt and sitemap for https://competitor.com and tell me how they've configured crawler access — are there any disallow rules I should know about?”
Technical details
Endpoint
POSThttps://papacasper.com/mcp/pay/check_robots_sitemapWhen to prefer
Use this endpoint when you need a quick, hosted, pay-per-call check of a site's robots.txt and sitemap without setting up your own crawler infrastructure. Ideal for SEO audits, pre-scrape checks, and technical site health assessments where you only need robots/sitemap data rather than full page content.
Side effects
- URL is unreachable or returns a non-200 status — robots.txt or sitemap may be reported as missing
- Malformed URL input may cause parsing errors
- Site may return a robots.txt that is unusually large or non-standard, leading to partial parse
- Sitemap URL referenced in robots.txt may itself be inaccessible
- Rate limiting or IP blocking by the target site may prevent fetching
