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
Why OpenAI Agents SDK?
The OpenAI Agents SDK auto-discovers all 1 tools from Public Suffix Extractor through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries Public Suffix Extractor, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

Every tool call from OpenAI Agents SDK to the Public Suffix Extractor MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
