Official endpoint

Operated by HTTP 511 network-auth (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 HTTP 511 network-auth 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 HTTP 511 network-auth MCP server?

Yes — HTTP 511 network-auth operates its own remote MCP server at agent-observatory-sensor.nolimit-observatory.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 HTTP 511 network-auth to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick HTTP 511 network-auth in the directory. No account or sign-in is needed. From then on, HTTP 511 network-auth's tools are available in every client you've connected to gate.

Do I need to host anything?

No. HTTP 511 network-auth runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the HTTP 511 network-auth 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.
