What your AI can do with Public suffix count
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “public-suffix”: Public suffix count.”
“Use “utc-time”: Current UTC timestamp.”
“Use “timezone”: Current time in a named IANA timezone.”
“Use “validate-json”: Check whether a body is valid JSON. The body is discarded.”
How secure is the Public suffix count MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Public suffix count holds up.
Official endpoint
Operated by Public suffix count (workers.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Public suffix count adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

Is there an official Public suffix count MCP server?

No. Public suffix count runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Public suffix count MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
