01 — WHY IT EXISTS

Norway's company registry, exposed to Claude.

Brønnøysundregistrene (Brreg) holds the canonical record of every registered business in Norway — names, org numbers, roles, subunits. The public API is excellent, but every agent that wants company data has to learn its shape from scratch. This MCP fixes that once.

02 — WHAT IT DOES

One server, every Brreg endpoint, idiomatic tool calls.

Drop it into Claude Code (or any MCP client) and the model gets typed tools for searching by name, looking up by org number, walking subunits, listing roles. No API key, no auth — Brreg is open data.
