Icelandic Law MCP Server

The Lagasafn alternative for the AI age.

Query 1,709 Icelandic statutes -- from Persónuverndarlög and Almenn hegningarlög to Lyfjalög, Stjórnarskrá, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Icelandic legal research is scattered across Althingi, Lagasafn (the official legal gazette), 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
• A legal tech developer building tools on Icelandic law
• A researcher tracing legislative provisions across 1,709 statutes

...you shouldn't need dozens of browser tabs and manual cross-referencing. Ask Claude. Get the exact provision. With context.

This MCP server makes Icelandic law searchable, cross-referenceable, and AI-readable.

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from Althingi/Lagasafn official sources
• Provisions are returned unchanged from SQLite FTS5 database rows
• Zero LLM summarization or paraphrasing -- the database contains statute text, not AI interpretations

Smart Context Management:

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

Technical Architecture:

Althingi/Lagasafn → Parse → SQLite → FTS5 snippet() → MCP response

Traditional Research vs. This MCP

Traditional Approach	This MCP Server
Search Lagasafn by statute number	Search by plain Icelandic: "persónuvernd samþykki"
Navigate multi-chapter statutes manually	Get the exact provision with context
Manual cross-referencing between laws	build_legal_stance aggregates across sources
"Is this statute still in force?" → check manually	check_currency tool → answer in seconds
Find EEA/EU basis → dig through EUR-Lex	get_eu_basis → linked EU acts instantly
Check multiple sites for updates	Daily automated freshness checks
No API, no integration	MCP protocol → AI-native

Traditional: Search Lagasafn → Download PDF → Ctrl+F → Cross-reference → Check EUR-Lex for EEA basis → Repeat

This MCP: "Hvaða ESB-reglur eru grundvöllur laga nr. 90/2018 um persónuvernd?" → Done.

EEA Law Integration

Iceland is an EEA member state but not an EU member. Iceland implements EU law via the EEA Agreement, including GDPR (as Regulation (EU) 2016/679 incorporated into EEA Annex XI), NIS2, and most of the EU single market acquis. This creates a close but distinct relationship with EU law.

Key areas of EEA-Icelandic law integration:

• GDPR (2016/679) -- incorporated into EEA Agreement; implemented via lög nr. 90/2018 um persónuvernd og vinnslu persónuupplýsinga
• NIS2 Directive (2022/2555) -- incorporated into EEA and implemented in Icelandic cybersecurity legislation
• eIDAS Regulation (910/2014) -- incorporated into EEA; supplemented by national e-signature provisions
• Financial Services Directives -- MiFID II, Solvency II, and related acts incorporated via EEA Agreement Annex IX
• Product Safety and Market Surveillance -- EEA-incorporated regulations apply directly

Note: Iceland, Liechtenstein, and Norway participate in the EU single market via the EEA Agreement. EU acts must be formally incorporated into the EEA Agreement before applying to Iceland. The EU tools in this server reflect EEA-incorporated acts and their Icelandic implementations.

Metric	Value
EEA Member	Since 1994
Legal System	Civil law (Nordic tradition)
Official Legal Gazette	Lagasafn (lagasafn.is)
Parliament	Althingi (althingi.is)
EUR-Lex Integration	Automated metadata fetching (EEA-incorporated acts)

See EU_INTEGRATION_GUIDE.md for detailed documentation.

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Althingi/Lagasafn publications. However:

• This is a research tool, not a substitute for professional legal counsel
• Verify critical citations against primary sources for court filings
• EEA/EU cross-references reflect EEA-incorporated acts; verify current incorporation status
• Always confirm current in-force status via Lagasafn before relying on a provision professionally

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 Lögmannafélag Íslands (Icelandic Bar Association) compliance guidance.
