Estonian Law MCP Server
<!-- ANSVAR-CTA-BEGIN --> > The Estonian 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/mcpClaude 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). <!-- ANSVAR-CTA-END -->
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.

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
| Category | Count | Details | |----------|-------|---------| | Statutes | 1,602 seadust | Comprehensive Estonian legislation from Riigi Teataja | | Provisions | 63,624 paragrahvi | Full-text searchable with FTS5 | | Premium: Case law | 0 (free tier) | Riigikohus and circuit court decisions planned | | Premium: Preparatory works | 163,383 documents | Seaduseelnõud and seletuskirjad | | Premium: Agency guidance | 0 (free tier) | Andmekaitse Inspektsioon guidance planned | | Database Size | ~116 MB | Optimized SQLite, portable | | Daily Updates | Automated | Freshness checks against Riigi Teataja |
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 ↑ ↑ Provision parser Verbatim database query ``
Traditional Research vs. This MCP
| Traditional Approach | This MCP Server | |---------------------|-----------------| | Search Riigi Teataja by seaduse nimetus | Search by plain Estonian: "isikuandmete töötlemine nõusolek" | | Navigate multi-chapter seadused manually | Get the exact provision with context | | Manual cross-referencing between seadused | build_legal_stance aggregates across sources | | "Kas see seadus on jõus?" → check manually | check_currency tool → answer in seconds | | Find EU basis → dig through EUR-Lex | get_eu_basis → linked EU directives instantly | | No API, no integration | MCP protocol → AI-native |
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.
| Metric | Value | |--------|-------| | EU Member State | Yes — since 1 May 2004 | | Eurozone | Yes — since 1 January 2011 | | EU References | Cross-references linking Estonian statutes to EU law | | Directives transposed | GDPR, NIS2, DORA, eIDAS, AI Act, PSD2, AML directives, and more | | EUR-Lex Integration | Automated metadata fetching | | e-Governance | Estonian digital ID legislation helped define eIDAS standards |
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
