With name search

claude mcp add dk-regnskab -e CVR_USER=… -e CVR_PASSWORD=… -- npx -y dk-regnskab-mcp

Name search uses the CVR register and needs free system-to-system credentials from the Danish Business Authority. Everything else works without them.

Five tools

Built for real filings

  • Group and parent are kept apart. Danish GAAP and IFRS mark them in opposite ways, and mixing them up can turn a loss into a profit.
  • Listed companies back to 2015. All three generations of IFRS tagging are read.
  • No guessing. If a filing has two different values for the same fact, the field is left empty with a note.
  • Balance check. If assets don’t equal liabilities and equity, the result says so.
  • Measured against 311 companies on 25 September 2026: 309 parsed, 2 without a machine-readable annual report, 0 errors.

What it can’t do

  • Only companies that file machine-readable annual reports. Sole proprietorships don’t.
  • Only what the company tagged. Management’s review and free-text notes are not included.
  • It has to run on your own computer or a server, not in a browser.
  • The data is public data from the Danish Business Authority. The project is not affiliated with it.
