# cvrdb.dk

> Danish companies from the public CVR register (Det Centrale Virksomhedsregister, Erhvervsstyrelsen): legal facts, annual-report key figures, owners, management, boards, auditors, production units and status history. Free to use, including in your own applications.

The site is in Danish. Every company and person page also exists as markdown: prefer it over HTML, it is smaller and has no scripts. Phone numbers, e-mail addresses and websites are left out of the markdown, MCP and API. Data is refreshed daily from CVR.

## For agents

- [MCP server](https://cvrdb.dk/mcp): Streamable HTTP, POST only, no key needed for reading. Tools: search_companies, get_company, search_actors, get_actor, companies_at_address, extract_companies (needs an API key).
- [Company as markdown](https://cvrdb.dk/virksomhed/dk/seier-capital-as/28098782.md): `/virksomhed/dk/<slug>/<cvr>.md`. A wrong slug redirects to the right one, so any slug works.
- Person or owner as markdown: `/virksomhed/aktoer/<enhedsnummer>.md`. Company pages and get_company link each person.
- [Developer docs](https://cvrdb.dk/developers): MCP setup for Claude, ChatGPT, Cursor and VS Code. MCP server card: https://cvrdb.dk/.well-known/mcp/server-card.json.
- [REST API](https://cvrdb.dk/api/v1): JSON, `Authorization: Bearer cvrdb_…`. 10,000 free lookups per day; create a key at https://cvrdb.dk/udtraek. [OpenAPI](https://cvrdb.dk/api/v1/openapi.json).
