nu:legal Deutsches Recht MCP Server

What changed here, as JSON. Two ways to read it. The cursor feed (send `kinds`, or `cursor`): everything that changed, oldest first, readable to the end without gaps: decisions added or changed, provisions with a new text (new Fassung, new provision, new law), and new citation links (decision X now cites Y, or decision Y gained a citer). Start with `kinds` (and `since`, default 7 days ago), then pass `next_cursor` back unchanged, with the same filters, until `has_more` is false; keep the cursor and poll with it later. Without those arguments: the provisions that got a new text recently, newest first. Poll it with `since` set to the newest `observed` you have processed. `observed` / `observed_at` is when the change reached this service, not when a court decided or a law came into force. Say so if you report a date. The window is the last 120 days; a provision's own history is listNormVersions.

What the corpus holds and what it does not: laws, decisions, courts, the version archive and the Länder covered. Call it before you report that something does not exist. The answer's `coverage` block is /v1/coverage: statutes per Land (`statutes`: full_text, partial or none), decisions per court level, the citation graph and what every version date is, all from one daily table. Example: {}

The text of one provision (§ or Article) as Markdown. `law` is the abbreviation ('BGB', 'StGB', 'DSGVO'; Hessen: 'HBO'), `ref` the number ('573', '3a'). For the text on a past date add `as_of` (YYYY-MM-DD; versions are held from 2019-06-10; for EU acts, the EMRK and some Landesrecht from the day their held text applies). The answer says how many versions are held (`versions_held`) and how many decisions cite the provision (`cited_by`). A version date is not always its Inkrafttreten: `date_basis` says what it is. For most federal law it is the day the text was first seen here; for an EU act it is the day its text applies (`applies_from`). With `compare_to` (YYYY-MM-DD) the answer adds `diff`, the word diff to the version stored for that date. DATES: each version carries `date_basis`, `in_force_from` (a date the source states) and `observed_from` (first seen here), each with its `*_basis`; the one we do not hold is null. Example: {"law": "BGB", "ref": "573"}

One lawyer's profile by `id` from search_lawyers: the official register entry with the date it was checked (chamber, admission, firm, office address, phone, fax, e-mail, website, beA id), Fachanwalt titles, contact data, languages, focus areas, opening hours and ratings per platform with the combined score. It holds what the public profile page (`profile_url`) shows, no more. Example: {"id": "8a0fa1b2c3d4e5f6"}

Find lawyers in Germany in the official register of the Bundesrechtsanwaltskammer. Give `city` (a German city or place; English names such as Munich or Cologne work; a 5-digit postcode is searched 10 km around, a smaller place 25 km), `name` (a lawyer or a firm), or both. Narrow with `area`, one of the 24 Fachanwalt areas in German or English ('Arbeitsrecht' or 'employment law', 'Strafrecht' or 'criminal law'), and `language` ('Türkisch' or 'Turkish'). Lawyers holding the Fachanwalt title for the area come first, then distance (postcode and place searches), then the combined rating. No paid placement; the order is no quality judgement. Next page: pass `next_offset` as `offset`. Each result has an `id` for get_lawyer and a `profile_url` to show the user. In-house lawyers (Syndikusrechtsanwälte) and lawyers who left the bar are not listed. Example: {"city": "Köln", "area": "Strafrecht", "language": "Arabic"}

Read a decision: its paragraphs, each with the court's Randnummer (`rn`) and a link. `case` takes an ECLI, our decision URL or an Aktenzeichen. Jump to a Randnummer with `around`, page with `offset` and `limit`. The first page also says how often the decision is cited and by whom. The answer carries `card`: typed `headnotes` (Leitsatz apart from Orientierungssatz), the `tenor` where the source marks it, `cited_norms`, `fundstellen`, `cite_as`; never generated text. Example: {"case": "bgh/2017-03-29/viii-zr-45-16", "around": 15, "limit": 5}

What one decision cites: the provisions (with how often) and the decisions it relies on. Example: {"case": "bgh/2017-03-29/viii-zr-45-16"}

Who cites this: the decisions citing a provision (`law` + `ref`) or a decision (`case`). Ranked by weight; `sort: "recent"` gives the newest first. Each citer links to the Randnummer where it cites. The graph is built over every decision held, federal, Land and EU courts alike, and links federal, EU and Land provisions; it does not link Hessen provisions, which answer `total: 0` with `coverage.complete_for_this_norm: false`: then fall back to `search` on the provision's wording. `coverage` carries the counts for the provision's jurisdiction. Example: {"law": "BGB", "ref": "573", "sort": "recent", "limit": 5} or {"case": "bgh/2017-03-29/viii-zr-45-16"}

Every stored version of one provision with its dates, newest first. Use it to see when a provision changed, then read a version with getNorm `as_of`. `at_archive_floor` marks a text that was already in force when the archive began. To compare two versions, call `getNorm(compare_to=…)`: the answer's `diff` is the word diff, and each side says what its date is (`date_basis`: `in_force`, `eurlex_consolidation`, `source_stated`, `observed` or `archive_floor`), so a floor date stays visible. DATES: each version carries `date_basis`, `in_force_from` (a date the source states) and `observed_from` (first seen here), each with its `*_basis`; the one we do not hold is null. Example: {"law": "BGB", "ref": "288"}

Look up German legal citations, up to 100 at once: a § or Article, an Aktenzeichen, an ECLI or a Fundstelle. Use it to find a decision by its docket and to check a citation before you state it. Pass each citation as you hold it, with court and date: they pick the right decision where a docket repeats. It never guesses. A miss is `not_in_corpus`; `attested` / `known_missing` means the decision exists but its text is not held; `date_mismatch` / `court_mismatch` mean your citation is wrong there. A found decision carries `cited_by`: how many decisions cite it, and the top citers with a link to the Randnummer where they do. Example: {"citations": ["BGH, Urteil vom 29.03.2017 - VIII ZR 45/16", "§ 573 Abs. 2 BGB"]}

Find statutes and decisions on a topic or a question, in one call. Use it when you hold no citation yet. German keywords or a full question both work; decisions are matched by meaning. A decision hit carries `url` (pass it as `case` to the decision tools), `ecli` and `cited_by`; a statute hit carries `slug` and `ref_norm` (pass them as `law` and `ref` to getNorm). Full text is held for Bayern, Brandenburg, Hessen, Nordrhein-Westfalen and Sachsen (see `getCoverage`). Hessen rows (`jurisdiction` 'HE'): pass `law_key` as `law` and `ref_norm` as `ref` to getNorm. Decisions can be filtered by `court`, `court_level`, `state`, `panel`, `from`/`to` and `decision_type`, and sorted with `sort` (relevance, weight: most cited first, newest); the answer counts them in `cases_total`. Example: {"q": "Eigenbedarf Kündigung Härtefall"}
