Fedlex Connector

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.

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.

    },

}

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.

    },
    "section": {
      "type": "string",
      "description": "Limit to a specific title, chapter, or part (e.g. 'Titre huitième', 'Zweiter Teil'). If omitted, returns the full act."
    },
    "language": {
      "type": "string",
      "enum": [
        "fr",

      "description": "Language (default: de)"
    },

      "type": "number",
      "description": "Page number for paginated results (default: 1). Large acts are split across multiple pages."
    }
  },
  "required": [
    "rs_number"

}
