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.

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.
