Query **4,531 Croatian statutes** -- from the Zakon o provedbi GDPR and Kazneni zakon to the Zakon o radu, Zakon o trgovačkim društvima, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

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

---

## Why This Exists

Croatian legal research means navigating Narodne novine, zakon.hr, and EUR-Lex for EU implementation status -- across a dense system of codes and implementing regulations. Whether you're:

- A **lawyer** validating citations before the Vrhovni sud (Supreme Court) or Ustavni sud (Constitutional Court)
- A **compliance officer** checking GDPR implementation status under the Zakon o provedbi Opće uredbe o zaštiti podataka
- A **legal tech developer** building tools on Croatian law
- A **researcher** tracing EU directive transposition across 4,531 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 Croatian law **searchable, cross-referenceable, and AI-readable**.
