Extract domain on Public Suffix Extractor
The AI cannot reliably determine that the TLD of "app.vinkius.co.uk" is ".co.uk" (not ".uk"). This engine uses the official Mozilla Public Suffix List to fragment hostnames with 100% accuracy. Extracts the true root domain, TLD, subdomain, and SLD from any hostname using the official Mozilla Public Suffix List. Handles complex TLDs like .co.uk, .com.br correctly
What the Public Suffix Extractor MCP Server unlocks
When an analytics agent processes URLs, it cannot guess that in app.vinkius.co.uk the TLD is .co.uk (not .uk). This MCP uses the official Mozilla Public Suffix List to fragment hostnames with 100% accuracy.
The Superpowers
- Official List: Uses the same Public Suffix List maintained by Mozilla and used by every major browser.
- Complex TLDs: Correctly handles .co.uk, .com.br, .org.au, .amazonaws.com, and 9,000+ other suffixes.
Frequently asked questions about the Public Suffix Extractor MCP Server
Why can't I just split the domain by dots?
Because TLDs like .co.uk, .com.br, and .org.au have multiple parts. Splitting by dots would incorrectly identify the root domain. The PSL has 9,000+ entries.
Does it handle cloud provider domains?
Yes. Domains like .amazonaws.com, .azurewebsites.net, and *.cloudfront.net are in the PSL and handled correctly.
Can I pass a full URL with protocol and path?
Yes. The engine automatically strips the protocol (http/https), path, and query parameters before parsing.
