ChatGPT Deep Research compatibility tool. Returns a ranked list of Swiss court decisions matching a query, each as {id, title, url, snippet}. Pair with `fetch` to retrieve a decision's full text by id. General (non-deep-research) clients should prefer `search_decisions`, which exposes filters (court, canton, date, language) and richer metadata.
ArgumentsA call is made on an account: it counts against an allowance and the publisher sees it, which is why this one asks who you are first.

Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine — this server runs on the publisher’s own infrastructure behind our gateway, and what you install is the connection to it.

ChatGPT Deep Research compatibility tool. Returns a ranked list of Swiss court decisions matching a query, each as {id, title, url, snippet}.

ChatGPT Deep Research compatibility tool. Fetches one Swiss decision's full text by id, returning {id, title, text, url, metadata}. The id comes from a `search` result (a decision_id like bger_6B_1234_2025; a docket number or BGE reference also resolves). General clients should prefer `get_decision`.

Example callreturns →
Use this tool to find COURT DECISIONS (Rechtsprechung): 1,050,000+ Swiss federal and cantonal decisions plus ~2,800 ECtHR decisions concerning Switzerland. Full-text search with keywords, phrases (in quotes), Boolean operators (AND, OR, NOT), prefix matching (word*), docket lookup (6B_1234/2025) and column-scoped search (regeste:keyword). Filter by court, canton, language, date range, chamber. Res
Takes no parameters.
Example callreturns →
Fetch a single court decision with full text. Look up by decision_id (e.g., bger_6B_1234_2025), docket number (e.g., 6B_1234/2025), or partial match. Full text is truncated at 200,000 characters for very long decisions. Set full_text=false to get only metadata and regeste.
Takes no parameters.
Example callreturns →
Use this tool to fetch SEVERAL decisions at once (1-10 ids) instead of calling get_decision repeatedly. Same data per decision — canonical citation strings, Markdown link, Regeste, metadata — in ONE call. Prefer this whenever you are about to read more than one decision from a search result: it is the difference between one tool call and ten, which matters because clients cap tool calls per turn.

Given a decision_id, show what it cites and what cites it. Uses the reference graph database with 9.65M citation edges. Returns resolved citations with confidence scores and unresolved references.
Takes no parameters.
Example callreturns →
Trace the appeal chain (Instanzenzug) for a decision. Shows prior instances (lower courts) and subsequent instances (appeals to higher courts). Reconstructs the full procedural path, e.g. Bezirksgericht → Obergericht → Bundesgericht. Uses the is_prior_instance flag from decision headers.

Find the most-cited decisions for a topic or statute. Authority ranking based on citation graph. Filter by statute (law_code + article), topic query, court, and date range. Top-3 results auto-attach a `pinpoint` field {e_number, matched_sentence, confidence, url, score, source} anchoring the most-relevant Erwägung — see system instructions U3 for how to surface it. Each result also carries citatio

Year-by-year decision counts showing jurisprudence evolution. Use with a statute reference (law_code + article), a text query, or both. Returns yearly counts with visual bar chart.

Build a research-only mock decision outline from user facts. Combines relevant Swiss case law retrieval with statute references. If possible, enriches statutes with Fedlex text excerpts. IMPORTANT: The tool may return clarification questions (high/medium priority). High-priority clarifications must be answered (via the clarifications parameter) before the tool will provide a conclusion. Call again

Structured case brief: regeste, Sachverhalt, key Erwägungen (first 12 only — for orientation, NOT a pinpoint ranking), Dispositiv, statutes, citation authority, related cases. Accepts BGE ref, decision_id, or docket. To pinpoint which Erwägung supports a specific claim, use find_relevant_erwaegung — never guess from key_erwaegungen alone.
Takes no parameters.
Example callreturns →
Structured decision fields: Sachverhalt (facts), Erwägungen as numbered paragraphs ('1', '1.1', '2.3'), Dispositiv (ruling), Regeste (BGE only). Federal decisions only; for cantonal use get_decision. Returns excerpts; for verbatim full text of one Erwägung, use get_erwaegung. PINPOINT POLICY: never guess. If user gave an e_number → verify with get_erwaegung. If user gave only a claim → use find_re

Example callreturns →
Verbatim text of ONE numbered Erwägung — the citable unit in Swiss practice (e.g. 'BGE 140 III 86 E. 2.3'). Use when the user already gave an e_number. If only a claim was given (no e_number): use find_relevant_erwaegung — never guess. Returns text + sibling Erwägung numbers. e_number: '1', '2.3', '5.2.1', …

Example callreturns →
Find which Erwägung paragraph(s) match a legal claim. Server-side FTS5+BM25 over per-paragraph text; returns top-k with confidence labels (high/medium/low) and a highlighted_snippet wrapping the matched sentence in <mark>…</mark> (quote it verbatim). When no_match=true or confidence=low, do NOT cite any Erwägung — report no_match. Federal decisions only. Replaces the 'always-E.-3.1' guessing patte

Return verbatim text from the Federal Council Botschaft (or Erläuterungsbericht) explaining the legislative purpose of a specific article.

Use this tool to retrieve and quote the VERBATIM text of Federal Council Botschaften (legislative messages). Where get_article_purpose answers 'why does Art. X exist?', this tool answers 'show me every Botschaft passage about TOPIC X'. Useful when the caller doesn't know which SR/article to ask for — e.g. starting from a concept like 'Vaterschaftsurlaub' or 'Klimaschutz'. Returns ranked passages (

Chronological story of a single statute article: current text + every linked Botschaft (enacted + amendments) + leading court interpretations + doctrinal commentary, all ordered by date.

X' — a single call return

Example callreturns →
Get the official Regeste (head-note) of a Swiss court decision. The Regeste is the court's own formulation of the legal rule established — for BGEs especially, this is the canonical citation target. Often references specific Erwägungen via '(E. 5.2.1)' which can then be retrieved verbatim with get_erwaegung. USE THIS when the user asks 'what does this case stand for' or 'what is the rule from this

Example callreturns →
Verify whether a Swiss court decision actually supports a legal claim. Uses an independent Sonnet judge to compare the claim against verbatim text from the decision (Erwägung if pinpoint given, else Regeste, else first portion of full text).

MANDATORY FINAL-STEP AUDIT of your draft answer. Checks five hallucination classes: (1) every case citation (BGE/BGer/BVGer/BStGer/BPatGer/MKGE and FR/IT forms) exists in the corpus and any pinpoint (E. X.Y / consid. X.Y) resolves to a real Erwägung; (2) every 'Art. X LAW' statute reference resolves (known abbreviation, existing article); (3) every quoted passage of 30+ chars appears verbatim in a

Get the canonical Swiss citation string for a decision reference. CALL THIS BEFORE writing any case citation in your response. Returns ready-to-embed citation_string (DE/FR/IT variants plus a canonical URL) and a verbatim rule_statement. If the reference doesn't exist, returns exists=false plus close_matches for typo-correction — DO NOT guess or construct citations yourself; if you get exists=fals

Use this tool for DIGESTED legislative history — per-article intent summaries and key arguments, not verbatim text.

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is a hosted endpoint: the publisher runs it and we connect to it. The scanner reads packages and source, and neither exists to read here, so there is no grade — not a withheld one, an unmeasured one. What can be checked instead is on Installation: what it asks to reach and what it writes.

Reviews are earned
Writing one takes an account with at least 50 real tool calls against Swiss Case Law in the last 90 days. That is the whole gate — there is no other way to post, which is why the counts beside each review are worth reading.

Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes an account with 50 real tool calls against it.
