Does this require my NordVPN password or any API keys?

No. LMCP reads the local NordVPN state already present on your Mac. There are no API keys, no cloud login, and no credentials sent anywhere — the diagnostic runs entirely on-device.

Can web AI assistants like ChatGPT use this tool?

Yes. Desktop clients such as Claude Desktop and Cursor connect locally via stdio, and web AIs like ChatGPT, Claude.ai, Grok and Perplexity connect through the LMCP Cloud Relay connector. The diagnostic still runs locally on your Mac.

Diagnose NordVPN on Mac with AI — nordvpn

The nordvpn_diagnose tool lets your AI assistant run a complete diagnostic check on NordVPN, right on your Mac. It inspects whether the NordVPN app is installed, whether you are logged in, your current connection status, whether the kill switch is active, and which protocols (like OpenVPN, NordLynx/WireGuard, IKEv2) are supported. Instead of clicking through settings yourself, you just ask in plain language.

A concrete example prompt you can type: "Is my NordVPN connected and is the kill switch on? Run a full diagnostic." The AI calls nordvpn_diagnose and replies with a clear summary of your VPN's real state.

Which AI agents work?

LMCP exposes nordvpn_diagnose to every major AI client. Desktop clients auto-configure over a local stdio connection, while web AIs connect through the LMCP Cloud Relay connector.

Desktop (auto-configure, local stdio): Claude Desktop, Cursor, VS Code (GitHub Copilot), Windsurf, Zed.
Web (via LMCP Cloud Relay): ChatGPT, Claude.ai (web), Grok, Perplexity.

One install, and all of these gain access to 150+ tools, including this one. Download LMCP to get started.

Automation

A diagnostic is most useful as the first step of a chain. Because nordvpn_diagnose returns structured state, your AI can act on the result: if it finds NordVPN is disconnected before you join a public Wi-Fi network, it can warn you; if the kill switch is off, it can remind you to enable it. Combine it with other LMCP tools — have the AI check your VPN, then open a Calendar event for your trip, draft a Mail note to your team that you're connecting securely, or set a Reminder to reconnect. The AI orchestrates the whole sequence from one request.

Context

The AI works with your real Mac, not a generic guess. nordvpn_diagnose reads the actual NordVPN installation and live connection state on your machine, so the answer reflects your true setup — your login session, your active server, your kill switch setting. There is no mock data and no "it depends" hand-waving: the assistant reports what is genuinely happening on your computer at that moment.

Productivity

Manually verifying a VPN means opening the app, checking the connection indicator, digging into Settings for the kill switch, and confirming the protocol — easy to forget a step before a sensitive call or a flight. With nordvpn_diagnose, one sentence gets you a complete, trustworthy status in seconds. It's ideal as a quick pre-flight check before remote work, travel, or accessing anything confidential, and it removes the guesswork of "am I actually protected right now?"

Privacy & GDPR

Everything runs locally on your Mac. nordvpn_diagnose inspects your VPN state on-device and returns the result straight to your AI client — nothing is copied to a server, stored, or sent to LMCP. There are no API keys and no cloud account for your data. This local-first design makes LMCP GDPR-compliant by architecture: your network and security details never leave the machine they belong to.
