Fedlex Connector tools (4)

write = sends, deletes, buys or posts
  • get_articleFree

    Retrieve a single article when you already know the EXACT article number (e.g. from a cross-reference). Do NOT call this tool repeatedly to search for provisions — use get_law_text instead to fetch the full act or a section and locate relevant articles in the text.

  • get_law_textFree

    Retrieve the official consolidated text of a Swiss federal act (or a specific title/chapter) directly from Fedlex (fedlex.admin.ch). This is the PRIMARY tool for answering Swiss law questions — always start here. Fetch the full act or a specific section, then locate relevant provisions in the returned text. Prefer this over get_article unless you already know the exact article number.

  • list_amendmentsFree

    List consolidation version dates for a Swiss federal act. Returns the dates each consolidated version took effect.

  • search_by_titleFree

    Search Swiss federal legislation titles in the Classified Compilation (RS/SR) on Fedlex. Use to find the RS number of a law when you know its name but not its number. Searches titles only, not article content. Returns only acts currently in force.

Fedlex Connector

Access Swiss Federal Law from Claude

A connector that gives Claude direct access to the official text of Swiss federal legislation on Fedlex, built on the Model Context Protocol (MCP). Covers all acts in the Classified Compilation (SR, RS) in German, French, and Italian.

Why This Exists

Swiss federal law is published exclusively on Fedlex, but the frontend is a JavaScript single-page application that Claude's built-in web tools cannot render. However, Fedlex exposes two machine-readable interfaces that work without JavaScript:

  • A SPARQL endpoint (fedlex.data.admin.ch/sparqlendpoint) for metadata queries
  • A static HTML filestore (fedlex.admin.ch/filestore/...) serving consolidated legislation

This MCP server bridges the gap: it queries SPARQL for metadata (RS numbers, consolidation dates, amendment history), fetches and parses the HTML for the actual legislative text, and returns it to Claude in a structured format. No proprietary database, no cache -- just a stateless bridge to Fedlex's open data infrastructure.

Setup

The server supports two transports: stdio for local use (Claude Code, Claude Desktop) and HTTP for remote use (claude.ai). You can use one or both.

The server is hosted at:

https://mcp.fedlex-connector.ch

claude.ai / Claude Desktop:

  1. Go to claude.ai
  2. Click Customize (Anpassen / Personnaliser / Personalizza) in the sidebar
  3. Click Connectors
  4. Click + → Add connector
  5. Click Add custom connector and paste the URL: https://mcp.fedlex-connector.ch

We suggest naming it "Fedlex Connector".

Claude Code:

claude mcp add --transport http fedlex https://mcp.fedlex-connector.ch

Once connected, Claude can answer questions like "What does art. 1 of the Swiss Civil Code say?" by pulling the text directly from Fedlex.

Deploying Your Own Instance

The server includes a Dockerfile for deploying to any cloud platform that supports Docker containers (Railway, Fly.io, Render, etc.). Set the PORT environment variable and the server runs in HTTP mode. Without PORT, it runs in stdio mode for local use.

Your MCP endpoint will be at https://your-domain. Verify with:

curl https://your-domain/health

Tools

searchbytitle
