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

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