Ukrainian Law MCP Server

The Zakon.rada.gov.ua alternative for the AI age.

Query 8,165 Ukrainian statutes -- from the Закон про захист персональних даних and Кримінальний кодекс to Цивільний кодекс, Господарський кодекс, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Ukrainian legal research means navigating zakon.rada.gov.ua, the Верховна Рада's official database, across thousands of statutes with inconsistent numbering and frequent amendments. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking Ukrainian data protection or cybersecurity obligations
• A legal tech developer building tools on Ukrainian law
• A researcher tracking legislative changes during Ukraine's EU accession process

...you shouldn't need dozens of browser tabs and manual cross-referencing. Ask Claude. Get the exact provision. With context.

This MCP server makes Ukrainian law searchable, cross-referenceable, and AI-readable.

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from zakon.rada.gov.ua (Верховна Рада) 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 statute identifier + chapter/section
• Cross-references help navigate without loading everything at once

Technical Architecture:

zakon.rada.gov.ua API --> Parse --> SQLite --> FTS5 snippet() --> MCP response
                            ^                        ^
                     Provision parser         Verbatim database query

Traditional Research vs. This MCP

Traditional Approach	This MCP Server
Search zakon.rada.gov.ua by statute number	Search by plain Ukrainian: "персональні дані згода"
Navigate multi-chapter 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 alignment -- dig through EUR-Lex	get_eu_basis -- linked EU directives instantly
Check multiple portals for amendments	Daily automated freshness checks
No API, no integration	MCP protocol -- AI-native

Traditional: Search zakon.rada.gov.ua --> Download PDF --> Ctrl+F --> Cross-reference with related statutes --> Check EUR-Lex for EU basis --> Repeat

This MCP: "Які вимоги щодо захисту персональних даних в Україні та як вони співвідносяться з GDPR?" -- Done.

EU Law Integration

Ukraine is an EU accession candidate under the EU-Ukraine Association Agreement (in force since 2017). Ukraine is actively harmonising its legislation with EU law as part of the accession process.

Key alignment areas:

• Data protection: Закон про захист персональних даних aligns with GDPR principles; further reforms are underway as part of accession requirements
• Cybersecurity: Ukrainian cybersecurity legislation is being aligned with NIS2 and the EU Cybersecurity Act
• E-commerce and digital markets: Alignment with EU Digital Single Market legislation
• Competition law: Ongoing alignment with EU competition framework

The EU bridge tools allow you to explore these alignment relationships -- checking which Ukrainian provisions correspond to EU requirements, and vice versa.

Note: EU cross-references reflect alignment and approximation relationships under the Association Agreement, not full transposition. Ukraine adopts its own legislative approach, and the EU tools help identify where Ukrainian and EU law address similar domains. Full transposition obligations increase as accession negotiations progress.

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from zakon.rada.gov.ua (Верховна Рада). However:

• This is a research tool, not a substitute for professional legal counsel
• Court case coverage is not included -- do not rely solely on this for case law research
• Verify critical citations against primary sources for court filings
• EU cross-references reflect alignment under the Association Agreement, not full transposition
• Ukrainian law is changing rapidly due to the ongoing EU accession process -- verify currency for any provision you rely on professionally
