MCP (Model Context Protocol) server that gives AI agents — Claude Desktop, Claude Code, or any MCP client — access to Danish phone-number data from nummeropslag.dk: company lookup from the official CVR business register, telecom operator + number type from the Danish number register, and a community spam/scam verdict.
