Connect

Claude Code (one line):

claude mcp add ansvar --transport http https://gateway.ansvar.eu/mcp

Claude Desktop / Cursor — add to claude_desktop_config.json (or mcp.json):

{
  "mcpServers": {
    "ansvar": {
      "type": "url",
      "url": "https://gateway.ansvar.eu/mcp"
    }
  }

Claude.ai — Settings → Connectors → Add custom connector → paste https://gateway.ansvar.eu/mcp

First request opens an OAuth flow at ansvar.eu/gateway. After signup, your client is bound to your account; tier (free / premium / team / company) determines fan-out, quota, and which downstream MCPs are reachable.

Self-host this MCP

You can also clone this repo and build the corpus yourself. The schema, fetcher, and tool implementations all live here. What is not in the repo is the pre-built database — TDM and standards-licensing constraints on the upstream sources mean we host the corpus on Ansvar infrastructure rather than redistribute it as a public artifact.

Build your own: run this repo's ingestion script (entry-point varies per repo — typically scripts/ingest.sh, npm run ingest, or make ingest; check the repo root).

The Fedlex alternative for the AI age.

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 -- 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.
