InternetData MCP Server

The official Model Context Protocol server for the InternetData API.

InternetData publishes IP and ASN databases: geolocation, anonymity, ownership and network data, as gzipped CSV and as MMDB. This server gives an AI agent four read-only tools over them - every database we publish and where your organization's license for each one stands, what is inside one, the digests to verify a copy you already hold, and your recent download history.

Getting Started

We host it at https://mcp.internetdata.io/mcp, and you sign in to it with your InternetData account. It also runs on your own machine from npm. Either way it sees where your organization's license for each database stands. Databases are licensed by contract rather than bought self-serve: see the API documentation, or request an evaluation if your organization doesn't have a license yet.

In Claude

In claude.ai, the desktop app or Cowork, add https://mcp.internetdata.io/mcp as a custom connector and choose Use Claude's published identity when asked. In Claude Code, install our plugin, which adds the server with skills:

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

Either way you sign in with your InternetData account, and Claude never sees your API key. The steps, the skills and how to disconnect: docs.internetdata.io/integrations/claude.

In any other MCP client

Point it at https://mcp.internetdata.io/mcp. A client that supports MCP authorization signs in the same way. One that doesn't can send a key instead, as Authorization: Bearer your-key.

On your own machine

You need an API key carrying the db.download scope. Add this to your MCP client's config:

{
  "mcpServers": {
    "internetdata": {
      "command": "npx",
      "args": ["-y", "internetdata-mcp"],
      "env": { "INTERNETDATA_API_KEY": "your-key" }
    }
  }
}

Requires Node.js 22 or newer. INTERNETDATA_BASE_URL overrides the endpoint if you need to point somewhere else.

Tools

Tool	What it answers
list_databases	Every database we publish, with its standing for your organization (licensed, expired or unlicensed) and the type and term of any license.
database_metadata	A database's columns, sample rows, row count, build date and file sizes.
database_checksum	The published digests for one database file.
list_downloads	Your organization's recent download attempts, refusals included.

Every tool is read-only.

Two spellings of a database id

list_databases answers a base id and a versions array:

{
  "base": "vpn_ip",
  "standing": "licensed",
  "versions": [{ "id": "vpn_ip_v1", "version": 1, "formats": ["csvgz", "mmdb"] }]
}

The base is what a license names. versions[].id is what a download names, and it is the one database_metadata and database_checksum accept. The tools say so in their own descriptions, so an agent generally gets this right on its own; it is worth knowing when you read a transcript where one was refused.

There is no download tool, deliberately

The published builds run to several GB, which is not something an agent should pull into a conversation. database_metadata is how you find out what a transfer would cost, and the client libraries or the API are how you actually move the bytes.

Reading the download history

list_downloads is a bounded window - at most 200 attempts, newest first - and it lists refusals alongside successes, because a denial and its http_status are what answer "it stopped working". A database missing from the answer means it is not in that window, never that it was never fetched.

Other Libraries

There are official InternetData client libraries available for many languages including PHP, Python, Go, Java, and Ruby. See our GitHub at https://github.com/internetdata for more.
