danskcvrapi-mcp

Official MCP server (Model Context Protocol) for DanskCvrApi — gives AI agents such as Claude Desktop, Claude Code and Cursor direct access to Danish company data from the CVR register.

The agent can look up companies, search, fetch financial statements, production units, persons and statistics — without writing a single API call.
