Query **4,873 Swiss federal laws** -- from Datenschutzgesetz (DSG/nFADP) and Strafgesetzbuch to Obligationenrecht, Fernmeldegesetz, and more -- directly from Claude, Cursor, or any MCP-compatible client.

If you're building legal tech, compliance tools, or doing Swiss legal research, this is your verified reference database -- the entire Systematische Rechtssammlung (SR), machine-readable.

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

## Why This Exists

Swiss legal research means navigating Fedlex, admin.ch, and scattered cantonal portals -- in three official languages. Whether you're:
- A **lawyer** validating citations in a brief or contract
- A **compliance officer** checking if a statute is still in force or how it aligns with EU law
- A **legal tech developer** building tools on Swiss federal law
- A **researcher** tracing legislative provisions across the SR numbering system

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

This MCP server makes Swiss federal law **searchable, cross-referenceable, and AI-readable** -- covering the full accessible SR corpus from Fedlex.
