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 Εθνικό Τυπογραφείο (Government Gazette) alternative for the AI age.

Query 21,119 Greek statutes -- from the Νόμος 4624/2019 (GDPR implementation) and Ποινικός Κώδικας to the Αστικός Κώδικας, κώδικας εταιριών, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Greek legal research is scattered across e-nomothesia.gr, the Εθνικό Τυπογραφείο (National Printing Office), 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 Greek law
• A researcher tracing legislative provisions across 21,119 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 Greek law searchable, cross-referenceable, and AI-readable.

Example Queries

Once connected, just ask naturally:

• "Αναζήτηση 'προστασία προσωπικών δεδομένων' -- ποιες υποχρεώσεις θεσπίζει ο Ν. 4624/2019;"
• "Ισχύει ακόμα ο Ποινικός Κώδικας (Ν. 4619/2019) ως προς το άρθρο 292;"
• "Βρες διατάξεις για την εταιρική διακυβέρνηση στον Αστικό Κώδικα"
• "Ποιες ευρωπαϊκές οδηγίες ενσωμάτωσε ο νόμος για την κυβερνοασφάλεια;"
• "Ποιοι ελληνικοί νόμοι υλοποιούν τον ΓΚΠΔ;"
• "Επαλήθευσε παραπομπή: Ν. 4624/2019, άρθ. 5"
• "Δημιούργησε νομική θέση για τις υποχρεώσεις γνωστοποίησης παραβίασης δεδομένων"
• "Συμμορφώνεται η ελληνική νομοθεσία με τις απαιτήσεις της οδηγίας NIS2;"

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from official Greek legal sources (e-nomothesia.gr, et.gr)
• 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
• Cross-references help navigate without loading everything at once

Technical Architecture:

e-nomothesia.gr / et.gr → Parse → SQLite → FTS5 snippet() → MCP response
                            ↑                      ↑
                    Provision parser        Verbatim database query

Traditional Research vs. This MCP

Traditional Approach	This MCP Server
Search e-nomothesia.gr by law number	Search by plain Greek: "προσωπικά δεδομένα συναίνεση"
Navigate multi-article 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 EU basis → dig through EUR-Lex	get_eu_basis → linked EU directives instantly
Check multiple sites for updates	Daily automated freshness checks
No API, no integration	MCP protocol → AI-native

Traditional: Search e-nomothesia.gr → Download ΦΕΚ PDF → Ctrl+F → Cross-reference → Check EUR-Lex for EU basis → Repeat

This MCP: "Ποιο άρθρο του Ν. 4624/2019 ενσωματώνει το άρθρο 9 ΓΚΠΔ για τις ειδικές κατηγορίες;" → Done.

EU Law Integration

Greece is an EU member state. Greek legislation directly transposes EU directives and implements EU regulations, creating a traceable mapping between Greek and EU law.

Key areas of EU-Greek law alignment:

• GDPR (2016/679) -- implemented via Νόμος 4624/2019 (Αρχή Προστασίας Δεδομένων Προσωπικού Χαρακτήρα)
• NIS2 Directive (2022/2555) -- transposed into Greek cybersecurity legislation
• eIDAS Regulation (910/2014) -- applicable directly; supplemented by Greek electronic identification rules
• DORA (2022/2554) -- digital operational resilience for financial sector entities
• AI Act (2024/1689) -- EU regulation applicable directly across all member states
• AML Directives -- implemented via Greek anti-money laundering legislation (Ν. 4557/2018 and amendments)

The EU bridge tools provide bi-directional lookup: find which Greek statutes implement a given EU act, or find which EU acts underpin a given Greek provision.

Metric	Value
EU Member State	Since 1981
Legal System	Civil law (continental European / Roman law tradition)
Official Gazette	Φύλλο Εφημερίδας της Κυβερνήσεως -- ΦΕΚ (et.gr)
Legislation Portal	e-nomothesia.gr
EUR-Lex Integration	Automated metadata fetching

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Greek legal publications (e-nomothesia.gr, ΦΕΚ). However:

• This is a research tool, not a substitute for professional legal counsel
• Verify critical citations against primary sources (ΦΕΚ) for court filings
• EU cross-references are extracted from Greek statute text, not EUR-Lex full text
• Always confirm current in-force status via e-nomothesia.gr 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 Δικηγορικός Σύλλογος Αθηνών / Ολομέλεια Δικηγορικών Συλλόγων Ελλάδος compliance guidance.
