956k Swiss court decisions: full-text search, citation graph, statute lookup (DE/FR/IT)
956k Swiss court decisions: full-text search, citation graph, statute lookup (DE/FR/IT). That is what the swiss case law mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
Spans 1875 to today, covers every Swiss federal court and all 26 cantonal court systems (plus regulators: FINMA, ComCo, FDPIC, IndepBC, ElCom, PostCom, ComCom), mirrors federal legislation directly from Fedlex SPARQL and cantonal legislation by direct portal scraping for all 26 cantons (LexWork: 18 cantons; SIL: NE + JU; ZH OpenData; TI RL — the same publishing systems the cantons operate themselves) with LexFind PDF as fallback supplementing 4 cantons for laws missing from their primary portals and as the discovery catalog for 33,000+ legislative texts. Includes **83,958 Botschaft amendment
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
The server publishes 11 tools. What each one is for:
Natural — language decision search (BM25 + synonym expansion + Haiku reranking, MRR@10 = 0.647 on a 100-query golden set)Leading — case discovery, citation networks, appeal chains, jurisprudence evolutionDecision — structure access** — get_decision_structure (Sachverhalt + Erwägungen + Dispositiv + Regeste split), get_erwaegung (verbatim Schweizer-citationMetric — ValueMethod — For whomSetup — 30 secondsDisk — NoneTools — 38 (no local update tools)Freshness — Nightly (automatic)Offline — NoRequires — Claude, ChatGPT, or Gemini CLI (see plans below)This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Swiss Case Law's toolset — Natural, Leading, Decision and 8 more — is a fair guide to whether it matches your workflow. It is maintained by ch.opencaselaw; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
