Estonian Law MCP Server

▶ Try this MCP instantly via Ansvar Gateway

50 free queries/day · no card required · OAuth signup at ansvar.eu/gateway

One endpoint, one OAuth signup, access from any MCP-compatible client.

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 flow at ansvar.eu/gateway. 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 isthe pre-built database — TDM and standards-licensing constraints on theupstream sources mean we host the corpus on Ansvar infrastructure ratherthan redistribute it as a public artifact.

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

The Riigi Teataja alternative for the AI age.

Query 1,602 Estonian statutes — from the Isikuandmete kaitse seadus (IKS) and the Karistusseadustik to the Tsiviilseadustiku üldosa seadus, Küberturvalisuse seadus, and more — directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Estonian legal research is concentrated in the Riigi Teataja — Estonia's model e-governance platform — but navigating 1,602 seadused across Estonian and cross-referencing with EUR-Lex remains manual work. Whether you're:

• A lawyer validating citations in a brief or leping
• A compliance officer checking obligations under IKS or the Küberturvalisuse seadus
• A legal tech developer building tools on Estonian law
• A researcher tracing legislative history from eelnõu to seadus

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

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

Example Queries

Once connected, just ask naturally (päringud toimivad eesti keeles või inglise keeles):

• "Mida ütleb isikuandmete kaitse seaduse (IKS) § 6 isikuandmete töötlemise põhimõtete kohta?"
• "Otsida 'isikuandmete kaitse' Eesti õigusaktidest"
• "Kas isikuandmete kaitse seadus (RT I, 04.01.2019, 11) on endiselt jõus?"
• "Millised on Karistusseadustiku sätted arvutikuritegude kohta?"
• "Millised Eesti seadused rakendavad NIS2 direktiivi?"
• "Otsida e-allkirja sätteid elektroonilise identimise ja e-tehingute usaldusteenuste seadusest"
• "Find provisions about data breach notification in Estonian law"
• "Validate the citation 'IKS § 6'"

What's Included

Verified data only — every citation is validated against official sources (riigiteataja.ee). Zero LLM-generated content.

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from Riigi Teataja (riigiteataja.ee) official sources
• 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 seadus abbreviation + paragraph number
• Cross-references help navigate without loading everything at once

Technical Architecture:

Traditional Research vs. This MCP

Traditional: Search Riigi Teataja → Download PDF → Ctrl+F → Cross-reference with EUR-Lex → Check AKI guidance → Repeat

This MCP: "Mis on IKS § 6 Euroopa õiguslik alus isikuandmete töötlemise põhimõtete kohta?" → Done.

EU Law Integration Tools (5)

EU Law Integration

Estonia is an EU member state (since 2004) and a digital governance pioneer. Estonian e-governance and digital identity legislation directly shaped EU instruments like eIDAS, making Estonia unique as both an implementer and an originator of EU digital law.

Key Estonian EU Implementations

• Isikuandmete kaitse seadus (IKS) — GDPR national implementation (isikuandmete kaitse)
• Küberturvalisuse seadus — Cybersecurity Act (NIS Directive transposition)
• E-identimise ja e-tehingute usaldusteenuste seadus — eIDAS transposition
• Makseasutuste ja e-raha asutuste seadus — PSD2 transposition

See EU_INTEGRATION_GUIDE.md for detailed documentation.

All content is sourced from authoritative Estonian legal databases:

• Riigi Teataja — Official State Gazette of Estonia (Eesti ametlik väljaanne)
• EUR-Lex — Official EU law database (metadata only)

Data Provenance

Automated Freshness Checks (Daily)

A daily GitHub Actions workflow monitors Riigi Teataja for changes:

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Riigi Teataja publications. However:

• This is a research tool, not a substitute for professional legal counsel
• Court case coverage is not included in the free tier — do not rely solely on this for kohtupraktika research
• Verify critical citations against primary sources (Riigi Teataja) for court filings
• EU cross-references are extracted from statute text and EUR-Lex metadata, not a complete implementation mapping
