What your AI can do with Iron City
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “city_info”: What Iron City is and how to enter + pay. Free to read (the gate sign).”
“Use “catalog”: List services and their prices (iron-cents; 100 = 1 USDC). Free to read.”
“Use “arena_list”: List open oracle-judged challenges incl. the drone Hover-Hold arena. Free to read.”
“Use “quote”: Get an x402 payment quote (the toll) for a resource, e.g. tool/cargo_check.”
How secure is the Iron City MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Iron City holds up.
Official endpoint
Operated by Iron City (sovereigntyempire.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 Iron City 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 Iron City
Choose Iron City in the gate directory. No sign-in needed.
Use it anywhere
Iron City's tools are live in every AI client you've connected — with rules and logging built in.

The Iron City MCP server at a glance
https://ironcity.sovereigntyempire.com/mcpQuestions, answered
Is there an official Iron City MCP server?
Yes — Iron City operates its own remote MCP server at ironcity.sovereigntyempire.com. 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 Iron City to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Iron City in the directory. No account or sign-in is needed. From then on, Iron City's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Iron City runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Iron City 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.
Is it free?
Yes — you can get started with gate for free and connect Iron City in minutes. No credit card required.
