Greek Law MCP Server

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;"

What's Included

Verified data only -- every citation is validated against official sources (Εθνικό Τυπογραφείο, e-nomothesia.gr). Zero LLM-generated content.

See It In Action

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: 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 Tools (5)

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.

See EU_INTEGRATION_GUIDE.md for detailed documentation.

Data Sources & Freshness

All content is sourced from authoritative Greek legal databases:

• e-nomothesia.gr -- Consolidated Greek legislation portal
• Εθνικό Τυπογραφείο / et.gr -- Official Government Gazette (ΦΕΚ -- Φύλλο Εφημερίδας της Κυβερνήσεως)
• EUR-Lex -- Official EU law database (metadata only)

Automated Freshness Checks (Daily)

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.
