Vietnamese Law MCP Server

The Cổng thông tin pháp luật (thuvienphapluat.vn) alternative for the AI age.

Query 93 Vietnamese statutes -- from the Luật An ninh mạng (Cybersecurity Law) and Nghị định về bảo vệ dữ liệu cá nhân to Bộ luật Hình sự, Bộ luật Dân sự, Luật Giao dịch điện tử, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Vietnamese legal research means navigating thuvienphapluat.vn and luatvietnam.vn, parsing Bộ luật, Luật, Nghị định, Thông tư, and Quyết định across multiple ministries, and manually tracking amendments from the National Assembly and Government. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking cybersecurity law obligations or personal data protection requirements
• A legal tech developer building tools on Vietnamese law
• A researcher tracing how legislation flows from National Assembly through ministerial decrees

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

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

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from thuvienphapluat.vn and luatvietnam.vn 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 luật/nghị định identifier + điều/khoản
• Cross-references help navigate without loading everything at once

Technical Architecture:

thuvienphapluat.vn → Parse → SQLite → FTS5 snippet() → MCP response
                       ↑                      ↑
                Provision parser       Verbatim database query

Traditional Research vs. This MCP

Traditional Approach	This MCP Server
Search thuvienphapluat by tên văn bản	Search by plain Vietnamese: "bảo vệ dữ liệu cá nhân"
Navigate multi-điều statutes manually	Get the exact provision with context
Manual cross-referencing between luật and nghị định	build_legal_stance aggregates across sources
"Luật này còn hiệu lực không?" → manual check	check_currency tool → answer in seconds
No API, no integration	MCP protocol → AI-native

Traditional: Search thuvienphapluat → Download PDF → Ctrl+F → Cross-reference with nghị định → Repeat

This MCP: "Điều nào trong Nghị định 13/2023 quy định về đồng ý của chủ thể dữ liệu?" → Done.

International & Comparative Law Alignment

Vietnam is not an EU member state, but Vietnamese law increasingly references and aligns with international frameworks, particularly in data protection, cybersecurity, and e-commerce.

ASEAN Framework Alignment

Vietnam is a member of ASEAN and participates in regional legal harmonisation:

ASEAN Framework	Vietnamese Alignment
ASEAN Digital Masterplan 2025	Luật An ninh mạng 2018, Nghị định 13/2023
ASEAN Cross-Border Data Flows	Under development
ASEAN Framework on Personal Data Protection	Nghị định 13/2023

WTO Commitments

WTO Agreement	Vietnamese Implementation
TRIPS	Luật Sở hữu trí tuệ (amended 2022)
GATS (e-commerce)	Luật Giao dịch điện tử 2023
TBT Agreement	Various technical standards legislation

Comparative EU Alignment

Vietnam has no EU adequacy decision. However, the international bridge tools allow you to explore comparative alignment:

• Nghị định 13/2023 (Personal Data Protection) vs. GDPR -- similar consent, purpose limitation, and data subject rights principles, but with Vietnam-specific data localization requirements
• Luật An ninh mạng 2018 vs. NIS2 -- overlapping cybersecurity incident reporting obligations with different scope and authority
• Luật Giao dịch điện tử 2023 vs. eIDAS -- electronic signature and authentication frameworks with partial alignment

Note: These tools identify comparative alignment, not legal equivalence. Vietnamese law operates under a civil law system with distinct legislative hierarchy (Luật > Nghị định > Thông tư > Quyết định).

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from thuvienphapluat.vn. However:

• This is a research tool, not a substitute for professional legal counsel
• Coverage is limited to 93 curated statutes -- not all Vietnamese legislation is included
• Court case coverage is not included -- do not rely on this for case law research
• Verify critical citations against primary sources for filings
• Ministerial guidance (Thông tư) is only partially covered -- check relevant ministry websites for complete guidance
• Amendment tracking -- Vietnamese law is frequently amended; always verify the current version
