The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • search unknown never probed

    Minimal search tool following the deep-research search/fetch convention. 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.

  • fetch unknown never probed

    Minimal fetch tool following the deep-research search/fetch convention. 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`.

  • search_decisions unknown never probed

    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. Results are relevance-ranked and enriched with citation counts, statute references and is_leading_case. Use offset to page. Most recent decisions: empty query + sort='date_desc' + court filter. Not for statutes (search_laws), commentary (search_scholarship), or administrative guidance (search_practice).

  • get_decision unknown never probed

    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.

  • get_decisions unknown never probed

    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. full_text defaults to FALSE here (unlike get_decision) because ten full judgments exceed connector response limits; set it true only for a short id list, and each text is excerpted with the cut disclosed. Ids not found are reported individually — the rest of the batch still returns.

  • find_leading_cases unknown never probed

    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 (surface it as 'E. <e_number>' when confidence is high or medium). Each result also carries citation_string_{de,fr,it} + canonical_url + is_leading_case + citation_count for ready-to-quote Swiss-format citations. A statute reference inside `query` ("Art. 29 BV") is used as the statute filter. When the query excludes every candidate, the page is relaxed to ranked OR and flagged `filters_relaxed: true` with a `note` — nearest neighbours, not on-point authority.

  • get_article_purpose unknown never probed

    Return verbatim text from the Federal Council Botschaft (or Erläuterungsbericht) explaining the legislative purpose of a specific article. Joins the verbatim Botschaft corpus (post-2003 BBl publications, Akoma Ntoso XML where available, PDF fallback otherwise) with the article-Botschaft link table. Returns one entry per source — original Botschaft + any amendment Botschaften. All paragraphs are verbatim text the LLM can quote with `bbl_citation, S. {page}` references. USE THIS when the user asks 'what was the purpose of Art. X' or 'what did Parliament intend' or 'why does Art. X exist'. Coverage is rolling — empty `sources` means the verbatim corpus hasn't ingested that article's Botschaft yet; fall back to get_doctrine for the digest layer.

  • search_botschaft unknown never probed

    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 (FTS5 BM25) with bbl_citation, page, section path, and an article anchor where the parser could identify one. Quote verbatim; every snippet has a stable Fedlex ELI URI. When no paragraph carries every term, the page is relaxed to ranked OR and flagged `filters_relaxed: true` with a `note`.

  • get_regeste unknown never probed

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 decision'. Available for ~54% of federal decisions (100% of BGE).

Returns {supports: yes|partial|no|contradicts|unrelated, confidence, supporting_excerpt, qualifying_excerpt, reasoning}. CALL THIS for any claim where citing the wrong authority would mislead the user — especially when paraphrasing a decision or drawing a proposition from a complex Erwägung.

  • attest_response unknown never probed

    MANDATORY FINAL-STEP AUDIT of your draft answer. Checks five hallucination classes: (1) every case citation (BGE/BGer/BVGer/BStGer/BPatGer/MKGE, FR/IT forms) exists and any pinpoint (E. X.Y) resolves to a real Erwägung; (2) every 'Art. X LAW' statute reference resolves; (3) quoted passages (60-400 chars) near a citation or statute reference are verbatim in that source (DE/FR/IT; audit_quotes, on by default); (4) decision dates adjacent to citations match the stored dates; (5) with audit_grounding=true, an LLM judge checks that each cited source supports the preceding claim (one call, ~3 s). Returns the annotated draft, an issues list and a `ledger` (denominator per check). It certifies the draft's own citations, quotations and statute references; it does not certify that no relevant authority is missing. CALL THIS BEFORE emitting any answer with a case citation, statute reference or quotation; set audit_grounding=true for 2+ citations. If ok=false, fix each issue; if ok=true, send linked_text verbatim.

  • cite unknown never probed

    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=false, either re-query with a close match or skip the citation entirely. Accepts any Swiss reference form: decision_id (bger_4A_747_2012), BGE reference (BGE 140 III 86), or docket number (4A_747/2012). Optional pinpoint ('2.3') generates the Erwägung-anchored citation and URL. A pinpoint the decision does not contain returns pinpoint_valid=false plus the UNPINPOINTED citation_string — never re-append the rejected pinpoint to it.

  • get_law unknown never probed

    AUTHORITATIVE LOOKUP for the text of any Swiss law article — federal OR cantonal — from two local mirrors. Federal (canton='CH', default): Fedlex mirror, all federal acts (OR, ZGB, StGB, ZPO, StPO, BV, SchKG, BGG, DBG, AIG, BVG, KVG …) in DE/FR/IT; names match in any language, case, dots or spaces (Cst, OPP2), treaties by common name (IPBPR, KRK, CISG) and former names (OG → BGG, noted; as_of gives the old edition). Cantonal: LexFind mirror, every act of all 26 cantons in the canton's language; name it 'ZH/StG' or pass canton. Use this BEFORE relying on training-data recall — statute text changes often and LLMs hallucinate article content. With as_of: the dated Fedlex edition in force on that date (snapshot_date, in-force window, link); always tell the user the edition date. PDF-only editions carry `text_status` 'heading_only' / 'empty' = no article text recovered; say so and give the Fedlex link. Examples: get_law(abbreviation='BV', article='8'); get_law(canton='ZH', sr_number='554.5', article='1').

Returns ranked snippets with article number, heading, law title, canton, and level ('federal' | 'cantonal'). Use this as the DEFAULT entry point when the user asks about any Swiss legal topic and you don't know which law or which jurisdiction applies. Filter with canton='ZH' (etc.) for cantonal-only, or jurisdiction='federal'/'cantonal' for explicit scoping. Examples: search_laws(query='Verjährung') — find statute-of-limitations provisions in federal + cantonal laws; search_laws(query='Hundehaltung', canton='ZH') — ZH dog-keeping rules; search_laws(query='Mietrecht', jurisdiction='federal') — federal-only tenancy law.

  • find_scholarship_citing_decision unknown never probed

    Find OA legal scholarship that cites a specific Swiss court decision. Reverse direction of the scholarship↔caselaw bridge: given a decision_id (e.g. 'bge_BGE_140_III_86' or 'bger_4A_571_2008'), return open-access publications that cite it in their full text. Citations are extracted deterministically by regex + lookup against the canonical decision corpus, so resolved citations are always to decisions we hold.

  • get_scholarship_full_text unknown never probed

    Fetch the full text of an OA legal publication by pub_id, on demand. Cached after first fetch so subsequent calls are instant. License-gated: only records under CC-BY-* (except CC-BY-ND), OA-Swiss-federal, or OA-author-permitted-reuse are extracted. ND/all-rights-reserved records return the upstream URL only. Use this when search_scholarship or get_scholarship returns only abstract/title and you need the article body to verify a claim or quote a passage.

  • get_materialien unknown never probed

    Look up Materialien for a Swiss federal law article. Returns up to three things: `sources` = per-article digests of legislative intent (BV and BGFA only — 167 articles); `botschaft_documents` = the Federal Council messages that concern this article, with BBl citation, title and Fedlex link (620 SR numbers, 19,809 article links); `amendment_refs` = the AS/BBl publication locators from the statute's own footnotes. Empty `sources` means no digest exists for that law, NOT that the law has no legislative history — read `botschaft_documents` and cite the BBl reference. For full text of a message use search_botschaft. A provision with nothing keyed to it is flagged `found: false` / `no_materialien: true` and lists `leading_cases`, a `doctrine` excerpt and `scholarship_citing_statute` instead — none of it is legislative history.

  • search_materialien unknown never probed

    Use this tool for DIGESTED legislative history — per-article intent summaries and key arguments, not verbatim text. COVERAGE IS NARROW: BV and BGFA digests (167 articles) plus BV debate transcripts, and nothing else. For any other law this returns 0 hits, which means 'outside this index', not 'no materials exist'. Prefer search_botschaft, which covers all 6,154 Federal Council messages verbatim, or get_materialien(law_code) for the messages linked to one statute.

  • search_legislation unknown never probed

    Use this tool to find WHOLE LAWS by name or subject — 33,000+ federal and cantonal enactments from LexFind.ch; the entry point for cantonal questions ('Hundegesetz Bern', 'loi sur l'énergie Vaud'). Not for article-level topic search (search_laws) or the core federal codes (get_law is instant there). All 26 cantons + federal, DE/FR/IT. Also the entry point for municipal regulations and federal ordinances outside the core Fedlex mirror. SINGLE-CALL MODE: set fetch_top_n_texts=1..3 and the top results are returned with the parsed full text + article list of the law itself — no follow-up get_legislation call needed. Ideal for 'what does cantonal law X say about Y' questions. For core federal codes (OR, ZGB, StGB, BV, StPO, ZPO, SchKG, BGG, DBG, IPRG, AIG, BVG, KVG etc.), prefer get_law / search_laws — they are instant and cover all three languages.

  • get_legislation unknown never probed

    Retrieve the FULL TEXT and article list of a specific Swiss law, federal or cantonal, by LexFind ID or SR/systematic number. For federal laws in the Fedlex mirror this is instant (local SQLite). For cantonal laws, the law is downloaded from LexFind as PDF, parsed with PyMuPDF, and segmented into articles (cached 30 days). Returns: title, entity, articles (article_num, heading, text), full_text, article_count. Use search_legislation first to find the right lexfind_id or systematic_number; then pass it here. For the core federal codes, get_law is still the fastest path.

Covered: BSV (AHV/IV/EL/EO/FamZ/BVG Wegleitungen, Kreisschreiben, Mitteilungen, every version), OAK BV (BVG Weisungen, Mitteilungen, drafts), WEKO (Bekanntmachungen, Erläuterungen, all versions), SECO (ArG commentary, AVIG-Praxis), BAG (KVG Kreisschreiben), SEM (Weisungen AIG/Asyl/BüG, Handbuch Asyl), BJ (SchKG Weisungen, Existenzminimum), FINMA, ESTV, BAFU; counts in the filter enums. Returns ranked excerpts with authority, number, date, PDF link. Superseded versions collapse to the newest per document; for past conduct pass include_superseded=true and take the version dated before the facts. NOT covered: cantonal administrations — Sozialhilfe (SKOS, cantonal Handbücher), Prämienverbilligung (IPV) — say so, do not imply absence of guidance. Pre-2017 federal decisions: search_decisions(court='ch_vb').

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
