What your AI can do with Postal Codes
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “lookup_postal_code”: Look up a postal code. Returns the places (city, state/region, latitude/longitude) matching the given postal code in the given country. Retu.”
How secure is the Postal Codes MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Postal Codes holds up.
Official endpoint
Operated by Postal Codes (invokera.com) 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 Postal Codes adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Postal Codes
Choose Postal Codes in the gate directory. No sign-in needed.

Postal Codes's tools are live in every AI client you've connected — with rules and logging built in.

Is there an official Postal Codes MCP server?
