Query **6,870 German federal statutes** -- from the BGB and StGB to the GG, BDSG, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

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

---

## Why This Exists

German legal research is scattered across gesetze-im-internet.de, dejure.org, rechtsprechung-im-internet.de, and DIP Bundestag. Whether you're:
- A **Rechtsanwalt** validating citations in a Schriftsatz or contract
- A **compliance officer** checking if a statute is still in force
- A **legal tech developer** building tools on German law
- A **researcher** tracing legislative history from Drucksache to statute

...you shouldn't need 47 browser tabs and manual PDF cross-referencing. Ask Claude. Get the exact provision. With context.

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