Nothing to run from here
OpenCaseLaw — Swiss Caselaw, Statutes & Doctrine is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| query | string | yes | Natural-language or keyword query. |
| limit | integer | no | Max results (default 10, max 50). |
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | Decision id from a search result (decision_id, docket, or BGE reference). |
Use this tool to find COURT DECISIONS (Rechtsprechung): 1,050,000+ Swiss federal and cantonal decisions plus ~2,800 ECtHR decisions concerning Switzerland.

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.

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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| decision_ids | array | yes | Decision ids, docket numbers or BGE references (e.g. ['bge_BGE_140_III_86', '6B_1234/2025']). |

Find OA legal scholarship that cites a specific Swiss court decision.

Citations are extracted deterministically by regex + lookup against the canonical decision corpus, so resolved citations are always to decisi

List the open-access legal scholarship sources currently indexed, with publication counts by source, type, and language. Use this to discover what corpora are available before searching.
No parameter schema on file.
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 n

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

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, o

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).

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 an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither: the repository linked on this page is where this record was collected from, not a copy of what the address serves, so it is not graded in its place. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.3.0.
