Vietnamese Law MCP Server

The thuvienphapluat.vn alternative for the AI age.

Query 93 Vietnamese laws -- from the Cybersecurity Law and Personal Data Protection to the Civil Code, Penal Code, and Enterprise Law -- 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

Why This Exists

Vietnamese legal research is scattered across thuvienphapluat.vn, vbpl.vn, vanban.chinhphu.vn, and luatvietnam.vn. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking cybersecurity or data protection requirements
• A legal tech developer building tools on Vietnamese law
• A business navigating enterprise law, investment, or tax regulations

...you shouldn't need to navigate multiple portals in Vietnamese. Ask Claude. Get the exact provision. With context.

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