Cn Law MCP server

@pipeworx/cn-law

Mainland China's national laws, administrative regulations, local regulations, judicial interpretations (司法解释), and the Supreme People's Court's official Guiding Cases (指导性案例) — original Chinese text, with promulgation and effective dates kept as separate fields where the source provides them.

Part of Pipeworx — an MCP gateway connecting AI agents to 1815+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

administrative regulations, local regulations, and judicial interpretations by title (exact) or keyword (fuzzy). Returns each result's record id, title, category, issuing body, promulgation date, effective date, and in-force status.

• cnsearchlaws(query, exact?, category?, limit?) — search national laws,

title, category, issuing body, promulgation date, effective date, in-force status, and whether cnlawarticle_text can extract text for it.

• cnlawdetail(id) — metadata for one record from cnsearchlaws:

article/provision (by number or citation, e.g. 13 or "第十三条"). Returns found: false with an explanation — never a fabricated or truncated snippet — when the article cannot be located or the underlying document cannot be read as text.

• cnlawarticle_text(id, article) — the Chinese text of ONE specific

regulations by title, from a second official source whose detail pages carry the full regulation text inline (rather than the PDF route cnlawarticle_text uses).

• cnsearchadmin_regulations(query, limit?) — search administrative

administrative regulation found via cnsearchadmin_regulations, plus its revision-date history.

• cnadminregulationtext(lawid) — full Chinese text of one

official Guiding Cases, newest batch first.

• cnguidingcases_list(page?) — index of the Supreme People's Court's

(关键词), holding (裁判要点), and the full case narrative.

• cnguidingcase_detail(id) — full text of one Guiding Case: keywords

Data sources

People's Congress Standing Committee), National Database of Laws and Regulations — national laws, administrative regulations, local regulations, and judicial interpretations (SPC/SPP/jointly issued), with promulgation and effective dates as separate fields. The publisher's own site is a JavaScript single-page app with no documented API; this pack calls the JSON endpoints that app itself calls, found by reading its bundle. Article-level text is not a field this source exposes directly — only a signed document-viewer link and highlighted search snippets — so cnlawarticle_text extracts it from the same official PDF rendition the site itself serves, via the shared extractPdfText helper (@pipeworx/shared).

• NPC Legislative Affairs Commission (全国人大常委会法工委, National

Database — a second official copy of administrative regulations, whose detail pages carry the full text inline as plain HTML. Its title search silently ignores the query term unless a second, undocumented parameter is also sent — cnsearchadmin_regulations asserts every returned title actually contains the query before returning it, so that failure mode cannot come back silently.

• Ministry of Justice (司法部), National Administrative Regulations

column — a static, paginated index with one full-text page per case.

• Supreme People's Court (最高人民法院), official Guiding Cases (指导性案例)

Not used, by design: the newer People's Court Case Library (人民法院案例库) and China Judgments Online (中国裁判文书网). Both sit behind a login wall for the calls that matter (the case library's search API answers "not logged in" with no session); this pack does not walk around that.
