How secure is the The 402 Wall MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how The 402 Wall holds up.
Official endpoint
Operated by The 402 Wall (404humans.xyz) 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 The 402 Wall adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.

Choose The 402 Wall in the gate directory. No sign-in needed.

The 402 Wall's tools are live in every AI client you've connected — with rules and logging built in.
