  4. Your API key

Claude can look up IP addresses, ASes and domains, look into any of our IP databases and tell you which ones your organization holds. It connects to our hosted MCP server, https://mcp.internetdata.io/mcp, you sign in with your InternetData account, and every tool is read-only.

In claude.ai, the desktop app and Cowork

Go to Customize > Connectors, click + Add and choose Add custom connector. Name it InternetData, enter https://mcp.internetdata.io/mcp and click Continue, then Continue again past the authentication settings Claude detected. Under Authentication choose Sign in now, and under OAuth client choose Use Claude's published identity: there's no client ID or secret to enter. Click Add, sign in, pick which of your organization's API keys the connection uses, and approve. To use it in a chat, turn it on under + > Connectors.

On a Team or Enterprise plan an Owner adds it once under Organization settings > Connectors, through Add and Custom > Web, with the same steps. Each member then clicks Connect on it under Customize > Connectors and signs in with their own account.

In Claude Code

Install the InternetData plugin. It adds the same server, with skills for looking up addresses, screening a list, looking into a domain or an AS, reading a database's contents, checking its files and downloads, and analyzing a copy:

console
/plugin marketplace add internetdata/claude-plugin
/plugin install internetdata@internetdata

It asks you to sign in the first time one of its tools runs. To add the server alone, without the skills:

bash
claude mcp add --transport http internetdata https://mcp.internetdata.io/mcp

Then run /mcp, pick internetdata and sign in. Once it's connected, ask something like "Where is 8.8.8.8, and whose network is it on?".

What the plugin adds

SkillWhat it does
check-ipsLooks up one address or a list: where each is, whose network, and whether it's a VPN, a proxy, Tor or a hosting provider.
review-trafficScreens an export or a log for anonymized traffic, keeping each answer next to its record.
investigate-domain-or-asLooks into a domain's DNS, ranges and disposable flag, or an AS's operator and prefixes.
database-filesAnswers which databases you hold, how big they are, whether your copy is intact and why a download failed.
analyze-databaseExplains a database's columns and sample rows, and in Claude Code analyzes a downloaded copy.

Your API key

Claude never sees the key. Our server uses it on your behalf, so every lookup counts against that key's plan. The database tools need a key with the db.download scope, which your organization's Default key has. Databases are licensed by contract. The Open ones are licensed to every organization from the start and are free under CC BY-SA 4.0. For the rest, see the API documentation or request an evaluation. Approving needs permission to share your organization's API keys, and asks you to confirm it's you. You can disconnect it at any time from the console, under Settings > Sessions & devices > Connected applications; access ends within about a minute.

Every other MCP client, and what each tool answers: MCP Server.
