ch-eli-mcp
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).
