Norwegian Law MCP Server

The Lovdata alternative for the AI age.

Query 3,400 Norwegian statutes -- from Personopplysningsloven and Straffeloven to Arbeidsmiljøloven, Avtaleloven, and more -- directly from Claude, Cursor, or any MCP-compatible client.

If you're building legal tech, compliance tools, or doing Norwegian legal research, this is your verified reference database.

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Norwegian legal research is scattered across Lovdata, Rettsdata, Stortinget publications, and EUR-Lex. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking if a statute is still in force or tracking EEA obligations
• A legal tech developer building tools on Norwegian law
• A researcher tracing legislative history from forarbeider to statute

...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 Norwegian law searchable, cross-referenceable, and AI-readable.

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from official Norwegian legal sources (Lovdata, Stortinget)
• Provisions are returned unchanged from SQLite FTS5 database rows
• Zero LLM summarization or paraphrasing -- the database contains regulation text, not AI interpretations

Smart Context Management:

• Search returns ranked provisions with BM25 scoring (safe for context)
• Provision retrieval gives exact text by law identifier + chapter/section
• Cross-references help navigate without loading everything at once

Technical Architecture:

Lovdata / Stortinget API --> Parse --> SQLite --> FTS5 snippet() --> MCP response
                               ^                        ^
                        Provision parser         Verbatim database query

Traditional Research vs. This MCP

Traditional Approach	This MCP Server
Search Lovdata by law name	Search by plain Norwegian: "personvern samtykke"
Navigate multi-chapter statutes manually	Get the exact provision with context
Manual cross-referencing between laws	build_legal_stance aggregates across sources
"Er denne loven i kraft?" -> check manually	check_currency tool -> answer in seconds
Find EEA basis -> dig through EUR-Lex	get_eu_basis -> linked EU directives instantly
Check 5+ sites for updates	Daily automated freshness checks
No API, no integration	MCP protocol -> AI-native

Traditional: Search Lovdata -> Navigate PDF -> Ctrl+F -> Cross-reference with forarbeider -> Check EUR-Lex for EEA basis -> Repeat

This MCP: "Hvilket EU-direktiv ligger til grunn for personopplysningsloven § 13 om informasjonssikkerhet?" -> Done.

EU/EEA Law Integration

Norway is an EEA member state implementing EU directives via the EEA Agreement. This means:

• GDPR is implemented in Norwegian law via Personopplysningsloven (2018)
• NIS2 Directive shapes Norwegian cybersecurity legislation
• eIDAS Regulation applies via the EEA Agreement to Norwegian eID schemes
• DORA and AI Act are being incorporated through the EEA Joint Committee process
• Norway participates in the EU internal market for goods, services, capital, and persons -- meaning the vast majority of EU single market legislation applies in Norway via EEA incorporation

The EU/EEA integration tools provide bi-directional lookup between Norwegian statutes and their EU/EEA basis.

Note: Norway is not an EU member state and does not participate in EU political institutions (Council, Parliament, Commission). EEA incorporation follows a separate process via the EEA Joint Committee. Some EU acts (Common Foreign and Security Policy, Customs Union, Agriculture/Fisheries) do not apply to Norway.

Data Sources & Freshness

All content is sourced from authoritative Norwegian legal databases:

• Lovdata -- Official Norwegian legal database (primary source)
• Stortinget -- Norwegian Parliament's legislative publications
• EUR-Lex -- Official EU law database (EEA metadata)

Automated Freshness Checks (Daily)

A daily GitHub Actions workflow monitors all data sources:

Source	Check	Method
Statute amendments	Lovdata date comparison	All 3,400 statutes checked
New statutes	Lovdata publications (90-day window)	Diffed against database
Preparatory works	Stortinget proposition feed (30-day window)	New proposisjoner detected
EEA reference staleness	Git commit timestamps	Flagged if >90 days old

The workflow supports auto_update: true dispatch for automated sync, rebuild, version bump, and npm publishing.

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Lovdata/Stortinget publications. However:

• This is a research tool, not a substitute for professional legal counsel
• Court case coverage is limited -- do not rely solely on this for case law research
• Verify critical citations against primary sources for court filings
• EEA cross-references are extracted from Norwegian statute text and EEA Joint Committee decisions, not EUR-Lex full text
• Licensing note: Lovdata's full database is commercial. This server uses publicly available content only

Before using professionally, read: DISCLAIMER.md | PRIVACY.md

Client Confidentiality

Queries go through the Claude API. For privileged or confidential matters, use on-premise deployment. See PRIVACY.md for Den Norske Advokatforening compliance guidance.

About Ansvar Systems

We build AI-accelerated compliance and legal research tools for the European market. This MCP server started as our internal reference tool for Norwegian law -- turns out everyone building for the Norwegian and EEA market has the same research frustrations.

So we're open-sourcing it. Navigating 3,400 statutes and 25,301 forarbeider shouldn't require a law degree.
