Query **45,899 Czech statutes** — from zákon č. 110/2019 Sb. (ochrana osobních údajů) and the Trestní zákoník to the Občanský zákoník, zákon o kybernetické bezpečnosti, and more — directly from Claude, Cursor, or any MCP-compatible client.

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

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

## Why This Exists

Czech legal research is scattered across e-Sbírka, zakonyprolidi.cz, ASPI, and EUR-Lex. Whether you're:
- A **lawyer** validating citations in a brief or smlouva
- A **compliance officer** checking obligations under zákon č. 110/2019 Sb. or zákon č. 181/2014 Sb.
- A **legal tech developer** building tools on Czech law
- A **researcher** tracing legislative history from důvodová zpráva to zákon

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

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