What your AI can do with NessGate
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “discover_domain”: Given a domain, read whatever it publishes at the standard machine-discovery locations (llms.txt, /.well-known/ard.json, /.well-known/agent-.”
“Use “connect_domain”: Given a domain AND the calling client's capabilities, return HOW the client can connect: one outcome (ready | credentials-required | incompl.”
“Use “check_readiness”: Given a domain, return each connectable resource it publishes with a readiness assessment (ready | credentials-required | incomplete | broke.”
How secure is the NessGate MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how NessGate holds up.
Security grade C
gate scanned 3 tools on Oct 4, 2026. A few things are worth a look before you connect.

Official endpoint
Operated by NessGate (nessgate.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 NessGate adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

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