The Retsinformation alternative for the AI age.
Query 62,764 Danish laws -- from Databeskyttelsesloven and Straffeloven to Selskabsloven, Forvaltningsloven, and more -- directly from Claude, Cursor, or any MCP-compatible client.
If you're building legal tech, compliance tools, or doing Danish legal research, this is your verified reference database.
Built by Ansvar Systems -- Stockholm, Sweden
Danish legal research means navigating retsinformation.dk, cross-referencing between lovbekendtgørelser (consolidated laws), forslag (bills), betænkninger (committee reports), and EUR-Lex. Whether you're:
...you shouldn't need dozens of browser tabs and manual PDF cross-referencing. Ask Claude. Get the exact provision. With context.
This MCP server makes Danish law searchable, cross-referenceable, and AI-readable.
Connect directly to the hosted version -- zero dependencies, nothing to install.
Endpoint: https://mcp.ansvar.eu/law-dk/mcp
Note: This server is hosted on Fly.io rather than Vercel because the database (1.6 GB) exceeds Vercel's 50 MB deployment limit. The endpoint is otherwise identical in behaviour to other Ansvar Law MCP servers.

| Traditional Approach | This MCP Server |
|---|---|
| Search retsinformation.dk by document number | Search by plain Danish: "personoplysninger samtykke" |
| Navigate multi-paragraph statutes manually | Get the exact provision with context |
| Manual cross-referencing between laws | build_legal_stance aggregates across sources |
| "Er denne lov stadig i kraft?" → check manually | check_currency tool → answer in seconds |
| Find EU basis → dig through EUR-Lex | get_eu_basis → linked EU directives instantly |
| Check multiple sites for amendments | Daily automated freshness checks |
| No API, no integration | MCP protocol → AI-native |
Traditional: Search retsinformation.dk → Download PDF → Ctrl+F → Cross-reference with betænkning → Check EUR-Lex for EU basis → Repeat
This MCP: "Hvad er EU-retsgrundlaget for Databeskyttelsesloven § 5 om samtykke?" → Done.
| Tool | Description |
|---|---|
search_legislation | FTS5 search on 620,940 provisions with BM25 ranking. Supports quoted phrases, boolean operators, prefix wildcards |
get_provision | Retrieve specific provision by law identifier + paragraph/section (e.g., "Straffeloven" + "263") |
check_currency | Check if a law is in force, amended, or repealed |
validate_citation | Validate citation against database -- zero-hallucination check. Supports "Straffelovens § 263", "Databeskyttelsesloven § 5" |
build_legal_stance | Aggregate citations from multiple laws for a legal topic |
format_citation | Format citations per Danish conventions (full/short/pinpoint) |
list_sources | List all available laws with metadata, coverage scope, and data provenance |
about | Server info, capabilities, dataset statistics, and coverage summary |
| Tool | Description |
|---|---|
get_eu_basis | Get EU directives/regulations that a Danish statute transposes (e.g., Databeskyttelsesloven → GDPR) |
get_danish_implementations | Find Danish laws implementing a specific EU act |
search_eu_implementations | Search EU documents with Danish implementation counts |
get_provision_eu_basis | Get EU law references for a specific provision |
validate_eu_compliance | Check transposition status of Danish statutes against EU directives |
Denmark is a full EU member state. Danish law directly transposes EU directives into national legislation:
| Danish Law | EU Basis |
|---|---|
| Databeskyttelsesloven | GDPR (Regulation 2016/679) |
| Implementeret e-Privacy | ePrivacy Directive (2002/58/EC) |
| Konkurrenceretten | EU Treaty Articles 101-102 (TFEU) |
The EU integration tools support bi-directional lookup: find which EU act a Danish statute transposes, or find all Danish laws implementing a given EU regulation.
Denmark and EU opt-outs: Denmark maintains opt-outs from certain EU policy areas (including Justice and Home Affairs, under Protocol 22 to the Maastricht Treaty). However, data protection law (GDPR), commercial law, and competition law are all fully aligned with EU frameworks. The EU tools in this MCP reflect full transposition coverage for these areas.
See EU_INTEGRATION_GUIDE.md for detailed documentation and EU_USAGE_EXAMPLES.md for practical examples.

THIS TOOL IS NOT LEGAL ADVICE
Statute text is sourced from official retsinformation.dk publications (Danish Ministry of Justice). However:
- This is a research tool, not a substitute for professional legal counsel
- Court case coverage in the free tier is limited -- do not rely solely on this for case law research
- Verify critical citations against primary sources for court filings
- EU cross-references are extracted from Danish statute text and EUR-Lex metadata, not substitute for full EUR-Lex legal text
- Municipal and regional regulations are not included -- this covers national Danish law only

Queries go through the Claude API. For privileged or confidential matters, use on-premise deployment. See PRIVACY.md for Advokatsamfundet (Danish Bar Association) compliance guidance.

We build AI-accelerated compliance and legal research tools for the European market. This MCP server started as our internal reference tool for Danish law -- turns out everyone building for the Danish and Nordic markets has the same research frustrations.
So we're open-sourcing it. Navigating 62,764 laws on retsinformation.dk shouldn't require a law degree.
