Liechtenstein Law MCP Server

Liechtenstein Law MCP Server

The Liechtenstein law corpus is now served through the Ansvar Gateway. Connect your AI assistant (Claude, Copilot, Cursor, custom MCP client) to https://gateway.ansvar.eu/mcp — one OAuth connection, free tier available, covering this corpus plus EU regulations, national law across dozens of audited jurisdictions (Europe + the US), and CVE/security intelligence, every result with a verbatim source citation. Start at https://ansvar.eu/docs/quickstart

Connect

Claude Code (one line):

claude mcp add ansvar --transport http https://gateway.ansvar.eu/mcp

Claude Desktop / Cursor — add to claude_desktop_config.json (or mcp.json):

{
  "mcpServers": {
    "ansvar": {
      "type": "url",
      "url": "https://gateway.ansvar.eu/mcp"
    }
  }
}

Claude.ai — Settings → Connectors → Add custom connector → paste https://gateway.ansvar.eu/mcp

First request opens an OAuth signup flow (setup details: ansvar.eu/docs/quickstart). After signup, your client is bound to your account; tier (free / premium / team / company) determines fan-out, quota, and which downstream MCPs are reachable.

Self-host this MCP

You can also clone this repo and build the corpus yourself. The schema, fetcher, and tool implementations all live here. What is not in the repo is the pre-built database — TDM and standards-licensing constraints on the upstream sources mean we host the corpus on Ansvar infrastructure rather than redistribute it as a public artifact.

Build your own: run this repo's ingestion script (entry-point varies per repo — typically scripts/ingest.sh, npm run ingest, or make ingest; check the repo root).

The liechtensteinisches-landesgesetzblatt.li alternative for the AI age.

Query 3,614 Liechtenstein statutes -- from the Datenschutzgesetz and Personen- und Gesellschaftsrecht to the Strafgesetzbuch, E-Commerce-Gesetz, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Why This Exists

Liechtenstein legal research means navigating gesetze.li, the LLGBl (Liechtensteinisches Landesgesetzblatt) publications, and cross-referencing EEA Agreement annexes. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking EEA-derived obligations under Liechtenstein law
• A legal tech developer building tools on Liechtenstein law
• A researcher tracing EEA implementation across Liechtenstein 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 Liechtenstein law searchable, cross-referenceable, and AI-readable.

Example Queries

Once connected, just ask naturally (queries in German):

• "Was sagt das Datenschutzgesetz (DSG) über die Einwilligung zur Datenverarbeitung?"
• "Ist das Personen- und Gesellschaftsrecht (PGR) noch in Kraft?"
• "Suche nach Bestimmungen über 'Datenschutz' im liechtensteinischen Recht"
• "Welche EU-Richtlinien setzt Liechtenstein über das EWR-Abkommen um?"
• "Was regelt das Strafgesetzbuch zum Thema Cyberkriminalität?"
• "Suche nach 'Gesellschaft' im PGR"
• "Welche liechtensteinischen Gesetze setzen die DSGVO um?"
• "Zitierformat für Art. 5 Abs. 1 DSG prüfen"

---

What's Included

Verified data only -- every citation is validated against official sources (gesetze.li / LLGBl). Zero LLM-generated content.

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from gesetze.li (official Liechtenstein legal database)
• 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 identifier and article number
• Cross-references help navigate without loading everything at once

Technical Architecture:

gesetze.li / LLGBl --> Parse --> SQLite --> FTS5 snippet() --> MCP response
                         ^                        ^
                  Provision parser         Verbatim database query

Traditional Research vs. This MCP

Traditional: gesetze.li suchen --> PDF herunterladen --> Strg+F --> EWR-Anhänge prüfen --> Wiederholen

This MCP: "Welche DSGVO-Anforderungen setzt das liechtensteinische DSG um?" --> Done.

EU/EEA Law Integration

Liechtenstein is a member of the European Economic Area (EEA) via the EEA Agreement, which means it implements the core EU Single Market legislation without being an EU member state.

Liechtenstein implements EU law via the EEA Agreement, including the GDPR equivalent, product liability directives, financial services regulations, and consumer protection rules. The EU bridge tools let you trace which Liechtenstein statutes implement which EU acts, and verify EEA compliance.

Note: Not all EU law applies to Liechtenstein. EEA coverage excludes Common Foreign and Security Policy, justice and home affairs (with exceptions), and other non-Single Market areas. The EU tools reflect EEA-relevant instruments.

Data Sources & Freshness

All content is sourced from authoritative Liechtenstein legal databases:

• gesetze.li -- Official consolidated Liechtenstein statutes (Liechtensteinisches Landesgesetzblatt)

Data Provenance

Automated Freshness Checks (Daily)

A daily GitHub Actions workflow monitors gesetze.li for changes:

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from gesetze.li (official Liechtenstein legal database). However:

• This is a research tool, not a substitute for professional legal counsel
• Court case coverage is not included -- do not rely solely on this for case law research
• Verify critical citations against primary sources (LLGBl) for court filings
• EEA cross-references reflect implementation relationships, not direct EU law applicability

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 bar association compliance guidance.
