Security check

How secure is the CardNexus MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how CardNexus holds up.

✓ Verified directory serverCardNexus · cardnexus.com

Official endpoint

Operated by CardNexus (cardnexus.com) at its documented MCP endpoint — not a third-party mirror or community re-host.

OAuth sign-in — your account, your rules

You grant access from your own CardNexus account and can revoke it there at any time. gate never sees your password.

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 CardNexus adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

CardNexus's server requires OAuth, so it can't be scanned anonymously — connect it in gate and the same scan runs automatically before it goes live.

How it works

Connected in three steps

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

FAQ

Questions, answered

Is there an official CardNexus MCP server?

Yes — CardNexus operates its own remote MCP server at mcp.cardnexus.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 CardNexus to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick CardNexus in the directory. You sign in to CardNexus via OAuth to grant access. From then on, CardNexus's tools are available in every client you've connected to gate.

Do I need to host anything?

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

Is the CardNexus 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.
