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
An object describing the complete redirect chain from the starting URL, including each intermediate URL visited, its HTTP status code, and the final resolved destination URL. May also include details on redirect type (301, 302, etc.) and total hop count.
Example use cases
SEO redirect audit for a page
“I'm doing an SEO audit — can you trace the redirect chain for https://mystore.com/sale and tell me every hop and final landing URL so I can check for unnecessary redirects?”
Debugging a broken redirect
“Users are complaining that https://app.mysite.com/login isn't loading right — can you follow the full redirect chain for that URL and show me where it ends up?”
Verifying a marketing link
“Before we launch this campaign, can you check the redirect chain for https://go.brandsite.com/promo2024 and confirm it resolves cleanly to the right landing page with no loops?”
Technical details
Endpoint
POSThttps://papacasper.com/mcp/pay/redirect_chain_checkWhen to prefer
Choose this endpoint when you need to trace all intermediate hops in an HTTP redirect chain rather than just checking a single status code. Ideal for SEO audits, debugging redirect issues, verifying marketing URLs, or detecting redirect loops. Prefer this over a simple HTTP HEAD check when the full chain path matters.
Side effects
- Invalid or malformed URL returns an error
- URL is unreachable or DNS fails to resolve
- Redirect loop detected causing the trace to terminate early
- URL requires authentication and redirects cannot be followed
- Timeout if redirect chain is excessively long
