What the publisher says

From the Northdata repository's README, as published. We do not edit it. Read it on GitHub

NorthData Connectors

Generic, product-side wrapper around the NorthData API — a Python CLI, an MCP server, and a Claude Skill, sharing one credit guard.

Unofficial project. This repository is an independent, community-maintained wrapper around the NorthData API. It is not developed, endorsed, or supported by NorthData GmbH. "NorthData" is a trademark of its respective owner; all company data accessed through this tooling remains subject to NorthData's own terms of service. For the official API documentation, see github.com/northdata/api.

This monorepo ships three layers on top of the NorthData API:

All three share one credit guard because NorthData charges per returned company, not per HTTP call.

Why this exists

NorthData's API is the canonical source for German commercial-register data (company profiles, owners, representatives, financials, publications). This repo makes it trivial to consume that data from:

  • Shell scripts and CI pipelines (northdata search ...)
  • AI agents in any MCP-capable client (Claude Desktop, Cursor, Claude Code, …)
  • Claude Skills that want domain-aware guidance without duplicating API code

The three layers never duplicate logic — the CLI is the library, the MCP server imports it, the Skill references the MCP tools.

Quick start

1. Get a NorthData API key

At . Set it as NORTHDATAAPIKEY.

2. Install what you need

# Shell usage
pipx install northdata-cli
export NORTHDATA_API_KEY=XXXX-XXXX
northdata suggest "Siemens" --pretty

# MCP server for Claude Desktop / Cursor / Claude Code
pipx install northdata-mcp
# then add the stdio server to your MCP client config
# (see northdata-mcp/README.md)

# Claude Skill — usage guidance for agents
npx skills add p-meier/northdata-connectors

3. Credit-safe by default

Every billable call respects two tiers:

Use --dry-run (CLI) or dry_run=true (MCP) to inspect a request without spending credits.
