brreg-mcp
MCP server for brreg — Norwegian company lookup in Brønnøysundregistrene / Enhetsregisteret by organisasjonsnummer (orgnr, org.nr).
brreg-mcp is an alias package. It contains no logic: it depends on
registry-mcp and its brreg-mcp
console script is the same entry point, serving the same five tools over stdio.
Install whichever name you searched for — you get the same server.
uvx brreg-mcp # identical to: uvx registry-mcp
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": "you@example.com" }
}
}
}
The same block works for Cursor (~/.cursor/mcp.json) and Claude Desktop
(claude_desktop_config.json).
