Compatible with every major AI agent and IDE
What is the Public Suffix Extractor MCP Server?
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.
Built-in capabilities (1)
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

Frequently asked questions
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.
How does Cline connect to MCP servers?
Cline reads MCP server configurations from its settings panel in VS Code. Add the server URL and Cline discovers all available tools on initialization.
Can Cline run MCP tools without approval?
By default, Cline asks for confirmation before executing tool calls. You can configure auto-approval rules for trusted servers in the settings.
Does Cline support multiple MCP servers at once?
Yes. Configure as many servers as needed. Cline can use tools from different servers within the same autonomous task execution.
