Tools & capabilities
Magic MCP tools
No tool names declared yet. Check the project README from the listing page.
Fedlex Connector tools 4
search_by_titleSearch 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.get_articleRetrieve 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_textRetrieve 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_amendmentsList consolidation version dates for a Swiss federal act. Returns the dates each consolidated version took effect.
