Estonian Law MCP Server

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 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 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:

Riigi Teataja API → Parse → SQLite → FTS5 snippet() → MCP response

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

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.

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

Client Confidentiality

Queries go through the Claude API. For privileged or confidential matters, use on-premise deployment. See PRIVACY.md for guidance consistent with Eesti Advokatuur (Estonian Bar Association) professional conduct standards.
