@foretak/brreg-mcp

MCP server for brreg — Norwegian company lookup in Brønnøysundregistrene / Enhetsregisteret by organisasjonsnummer (orgnr, org.nr).

This is an alias package. It contains no logic: it launches the Python server published on PyPI as brreg-mcp, which is itself an alias of registry-mcp — the same five tools, the same entry point. Install whichever name you searched for; you get the same server. You need Python 3.12+ and one of uv or pipx on your PATH.

uvx brreg-mcp             # identical to: uvx registry-mcp
npx -y @foretak/brreg-mcp # the same, launched from Node

Add to Claude Code

claude mcp add brreg-mcp -- uvx brreg-mcp

{
  "mcpServers": {
    "brreg-mcp": {
      "command": "uvx",
      "args": ["brreg-mcp"],
      "env": { "REGISTRY_MCP_CONTACT_EMAIL": "[email protected]" }
    }
  }
}

The same block works for Cursor (~/.cursor/mcp.json) and Claude Desktop (claude_desktop_config.json). No install at all, using the hosted server:

claude mcp add brreg-mcp --transport http https://api.foretak.dev/mcp
