What you can do

What your AI can do with PostCode Check

Real prompts you can type the moment it's connected — no setup, no docs to read.

“Use “validate_postcode”: Check whether a postal code has a valid format for a country and return its normalized form (uppercase, official space or hyphen), a format.”

“Use “list_countries”: List every supported country and territory with its ISO code, English name, whether it uses postal codes, a format example and the local nam.”

Security check

How secure is the PostCode Check MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how PostCode Check holds up.

✓ Verified directory serverPostCode Check · workers.dev

Official endpoint

Operated by PostCode Check (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 PostCode Check adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

FAQ

Questions, answered

Is there an official PostCode Check MCP server?

Yes — PostCode Check operates its own remote MCP server at postcodecheck.mike-tusa.workers.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

How do I connect PostCode Check to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick PostCode Check in the directory. No account or sign-in is needed. From then on, PostCode Check's tools are available in every client you've connected to gate.

Do I need to host anything?

No. PostCode Check runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the PostCode Check 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.
