Query **12,045 Lithuanian statutes** -- from the Asmens duomenų teisinės apsaugos įstatymas and Baudžiamasis kodeksas to the Civilinis kodeksas, Darbo kodeksas, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by [Ansvar Systems](https://ansvar.eu) -- Stockholm, Sweden

## Why This Exists

Lithuanian legal research is scattered across e-Seimas, TAR (Teisės aktų registras), 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 Lithuanian law
- A **researcher** tracing legislative provisions across 12,045 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 Lithuanian law **searchable, cross-referenceable, and AI-readable**.
