Ch Eli

MCP server for Swiss federal legislation via Fedlex, the Federal Chancellery's official publication platform. Fedlex is genuinely ELI-native (European Legislation Identifier) even though Switzerland is not an EU member. Multilingual: German, French, Italian, English.

What this is not

This connector returns metadata (title, SR number) via SPARQL - not the operative text of the law. source_url points to the public Fedlex page where the full text lives.

Tools

Tool	Purpose
ch_search_acts	Full-text search over act titles, in one of four languages
ch_get_act	Full detail for one act by its Fedlex ELI URI

Every response carries lex_uri (the native ELI URI - not invented, taken directly from Fedlex), source_url (the public HTML page), and human_readable_citation (e.g. "Bundesverfassung der Schweizerischen Eidgenossenschaft (SR 101)" - the SR number is Switzerland's own Systematische Sammlung / Classified Compilation citation convention).
