Security check

How secure is the Address To Zip MCP server?

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

✓ Verified directory serverAddress To Zip · addresstozip.jp

Official endpoint

Operated by Address To Zip (addresstozip.jp) 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 Address To Zip 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 Address To Zip MCP server?

Yes — Address To Zip operates its own remote MCP server at addresstozip.jp. 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 Address To Zip to Claude or ChatGPT?

Do I need to host anything?

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

Is the Address To Zip MCP server safe to connect?
