PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • ipapi_lookup_ip

    Look up one IPv4 or IPv6 address in ipapi.is: owner company, network, abuse contact, location, and the flags is_datacenter, is_vpn, is_proxy, is_tor, is_abuser, is_mobile, is_crawler. Spends 1 request of your ipapi.is quota.

  • ipapi_lookup_asn

    Look up one autonomous system (AS number) in ipapi.is: organization, registry, type, country and announced routes. Spends 1 request of your ipapi.is quota.

  • ipapi_bulk_lookup

    Look up up to 100 IP addresses and AS numbers in one ipapi.is request. The result is an object keyed by the entries you sent. Every entry spends 1 request of your ipapi.is quota. Duplicates and invalid entries are dropped silently by ipapi.is.

Common questions

Is ipapi.is MCP by usefulapi safe?

It passed 3 of 3 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 in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.4.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, debuff

ipapi.is MCP by usefulapi

Use your ipapi.is account from Claude, Cursor, or any MCP client. Look up IP addresses and AS numbers: owner, abuse contact, location, and VPN, proxy, Tor and datacenter flags. Hosted, no local install: connect with your own credentials.

Live endpoint: https://ipapi-is.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://ipapi-is.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http ipapi-is https://ipapi-is.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "ipapi-is": { "url": "https://ipapi-is.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your ipapi.is credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/ipapi-is/

On first connect you provide your ipapi.is API key (copy it from your ipapi.is dashboard). The server validates it and stores it per user. No keys go in config files.
