What io.github.hellosverre/brreg does

MCP server for Norway's Brønnøysund business registry — lookup, search, roles.

README

brreg-mcp

MCP server for the Norwegian Central Coordinating Register for Legal Entities (Brønnøysundregistrene / Enhetsregisteret). Gives Claude Code and other MCP-compatible clients direct access to Norwegian company data — lookup, search, roles, subunits, and live updates.

No API key needed. Data is served by the free, public Brønnøysund Open Data API.

Why

Norwegian devs, accountants, and analysts constantly need to look up orgnumbers, find board members, or track subsidiary changes. Doing it through the web UI is slow; doing it with curl loses context. With this MCP, you just ask Claude.

Install

Claude Code

Add to your MCP config (~/.claude/settings.json or per-project .claude/settings.json):

{
  "mcpServers": {
    "brreg": {
      "command": "npx",
      "args": ["-y", "brreg-mcp"]
    }
  }
}

Restart Claude Code. Verify with /mcp — you should see brreg listed with 5 tools.

Claude Desktop

claude_desktop_config.json:

{
  "mcpServers": {
    "brreg": {
      "command": "npx",
      "args": ["-y", "brreg-mcp"]
    }
  }
}

Cursor / Windsurf / Zed / any MCP client

Same command: npx, args: ["-y", "brreg-mcp"] configuration.

Local development

git clone https://github.com/hellosverre/brreg-mcp
cd brreg-mcp
npm install
npm run build

Then point your MCP client at node /absolute/path/to/brreg-mcp/dist/index.js.

Tools

Tool	What it does
`lookup_company`	Full details for one company by its 9-digit orgnr — name, address, NACE codes, employees, VAT status, bankruptcy, foundation date.
`search_companies`	Search by name and optional filters (municipality, org form, industry code, VAT-registered, bankruptcy status). Paginated.
`get_company_roles`	All registered roles (board, CEO, chair, auditor, sole proprietor) for a company.
`search_subunits`	Find subunits (branch offices, production sites) — scope to a parent company or by municipality/industry.
`get_recent_updates`	Feed of entity changes for monitoring new registrations, bankruptcies, status shifts.

Example prompts

"Look up orgnr 984661177 and show me the board."

"Find all VAT-registered software consultancies (NACE 62.010) in Oslo."

"List every subunit of Vygruppen AS."

"What Norwegian companies were just registered in the last hour?"

Data source

All data comes from data.brreg.no. Per Brønnøysund's open data terms, the data is free to use. Some endpoints (roles with personal identification numbers) require Maskinporten authentication and are not exposed by this server.

Development

npm install          # install deps
npm run dev          # run server in watch mode via tsx
npm run smoke        # hit the real brreg API to verify connectivity
npm run build        # compile to dist/
npx tsx scripts/mcp-probe.ts  # end-to-end stdio test
