Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "netip": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/labaccessnow/netip-mcp:0.1.0"
      ]
    }
  }
}

Run this in your terminal

claude mcp add netip -- docker run -i --rm ghcr.io/labaccessnow/netip-mcp:0.1.0

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "netip": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/labaccessnow/netip-mcp:0.1.0"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "netip": {
      "type": "stdio",
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/labaccessnow/netip-mcp:0.1.0"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

What it can do

Common questions

Is whatismynetip safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

netip-mcp

The whatismynetip.com toolbox as tools your coding agent can call. Subnet math, "what runs on this port and should it be open", MAC vendor lookups, DNS and blocklist checks, the certificate a host actually serves, and the IP the internet sees you as.

Free, MIT, no account, no telemetry. The site's own tools run in your browser; this runs the same logic next to your agent.

Install

Pin the version.

Claude Code

claude mcp add netip -- npx -y github:getlarkwright/netip-mcp#v0.1.1

Claude Desktop, Cursor, or any client with a JSON config

"mcpServers": { "netip": { "command": "npx", "args": ["-y", "github:getlarkwright/netip-mcp#v0.1.1"] } } }

Docker

"mcpServers": { "netip": { "command": "docker", "args": ["run", "-i", "--rm", "ghcr.io/getlarkwright/netip-mcp:0.1.1"] } } }

Node 18 or newer for the npx route. Also in the official MCP registry as io.github.getlarkwright/netip-mcp.

Tools

Tool	What it answers	Network
`subnet_calc`	Network, mask, wildcard, broadcast, host range and counts for a CIDR — IPv4 and IPv6, /31 and /32 done right	none
`ip_in_subnet`	Is this address inside that block?	none
`ip_convert`	IPv4 as dotted, integer, hex, binary — from any of them	none
`ipv6_normalize`	Expanded and RFC 5952 compressed forms, and what kind of address it is	none
`mac_lookup`	Vendor from the full IEEE registry (~40,000 assignments, bundled), plus the multicast and locally-administered bits	none
`lookup_port`	What runs on a port, and whether to expose it — 100 ports written up by hand, searchable by service	none
`dns_lookup`	A, AAAA, MX, TXT, NS, CNAME, CAA, SOA, PTR, SRV over DNS-over-HTTPS	DoH
`reverse_dns`	PTR for an IPv4 or IPv6 address	DoH
`dnsbl_check`	Five common blocklists, honest about the ones that refuse public resolvers	DoH
`tls_inspect`	The certificate a host actually serves: expiry, SANs, chain verification, protocol, cipher	direct TLS
`my_public_ip`	The address the internet sees, edge location, ASN, reverse DNS, datacenter/VPN hint	Cloudflare trace + Team Cymru DNS

lookup_port

The one I reach for most. The port pages on the site are opinionated — every port carries a verdict:

Port 3389/tcp+udp — RDP (Remote Desktop Protocol)

Category remote access Software Windows Remote Desktop Services, xrdp, FreeRDP server, Windows Admin Center hosts Exposure NEVER — do not expose to the internet

Internet-facing RDP is the most common initial-access route for ransomware crews, who credential-stuff it around the clock; put it behind WireGuard, Tailscale or an RD Gateway …

Ask by number, or search: lookup_port with query: "redis" finds 6379. detail: true adds the full write-up and FAQ.

What it does not do

No account, no signup, no key.
No telemetry. Nothing about your usage goes anywhere.
Nothing of yours is read from disk. The only file it opens is its own bundled OUI table.
The local tools never open a socket. The network tools talk only to public services — Cloudflare and Google's DNS-over-HTTPS resolvers, Cloudflare's trace endpoint, Team Cymru's ASN DNS, and whichever host you point tls_inspect at. tls_inspect refuses anything that resolves to private or reserved space, so it cannot be turned on your own network.
"Is my port reachable from outside?" needs a machine outside your NAT to try the connection. That is what whatismynetip.com/port-checker does; a local tool cannot.

The port data and the calculators are the same ones the site uses, so the two stay in step.
