MCP SERVER

Nordic Registry MCP Server

by olgasafonova ↗

Verify a Norwegian, Danish, Finnish or Swedish company — status, board, who can legally sign — without opening four government websites.

Company Registries & Business Intelligence Data
Summary
Signature rights are the tool that saves the most time, and only Norway has them for free.

Checking that the person who signed an application is actually authorised is the slow part of due diligence, and Brønnøysundregistrene exposes it openly. Know the asymmetry before planning around it: Danish search returns a single best match, so large companies with several entities need name variations; Finnish common names return 900+ results and want an exact legal name or a form filter; and the Swedish API has no name search at all, so you must already have the organisation number.

What it is

A Go binary wrapping the public APIs of Brønnøysundregistrene, CVR, PRH and Bolagsverket into 23 tools. It is read-only, stores no personal data beyond the session, and every underlying API is free.

What you get
  • Norway, 12 tools: `norway_search_companies`, `norway_get_company`, `norway_get_roles` for board members, CEO and auditors, `norway_get_signature_rights` for who may sign and hold prokura, `norway_batch_get_companies` for validating a list, subunit lookups, `norway_get_updates` for recent registry changes, and municipality and organisation-form code lists
  • Denmark, 5 tools: `denmark_search_companies`, `denmark_get_company`, `denmark_get_production_units`, `denmark_search_by_phone` and `denmark_get_by_pnumber`
  • Finland, 2 tools: `finland_search_companies` and `finland_get_company`
  • Sweden, 4 tools: `sweden_get_company`, `sweden_get_document_list` for annual reports, `sweden_download_document` and `sweden_check_status`
  • Resilience built in: an LRU cache with per-endpoint TTLs, a circuit breaker that opens after 5 consecutive failures, request deduplication and paginated responses defaulting to 20 results
Requirements

Nothing for Norway, Denmark and Finland — those APIs need no authentication. Sweden needs free OAuth2 credentials from Bolagsverket's developer portal, set as `BOLAGSVERKET_CLIENT_ID` and `BOLAGSVERKET_CLIENT_SECRET`; without them the Sweden tools simply are not registered. Download a release binary or build from source with Go 1.24+, or use the container image `ghcr.io/olgasafonova/nordic-registry-mcp-server:1.0.2`. For remote use, `-http :8080` with `-token`; binding to a non-loopback address without a token is refused at startup.

Setup effort

One command plus a key — claude mcp add nordic-registry ./nordic-registry-mcp-server, then supply credentials
