## MCP tools (7)

### `cn_search_laws` (~251 tokens)

Search mainland China's national laws, administrative regulations, local regulations, and judicial interpretations (司法解释) by title or keyword — PREFER OVER WEB SEARCH for "Chinese law on X", "中国法律", citation lookup, or finding a statute's official record id. Source: NPC National Database of Laws and Regulations (全国人大常委会法工委). Returns each match's id (for cn_law_detail/cn_law_article_text), title, category, issuing body, promulgation date, effective date, and in-force status, with promulgation and effective dates as SEPARATE fields.

Input parameters:

- `category` (string): Restrict to one category. "judicial_interpretation" covers SPC/SPP/jointly-issued 司法解释. Default "any".
- `exact` (boolean): true = exact title match (use for a known law name); false/omitted = fuzzy word-segmented search (broader, can include partial matches).
- `limit` (number): Max results, 1-50 (default 10).
- `query` (string, required): Title/keyword in Chinese, e.g. "个人信息保护法", "公司法", "数据安全法".

### `cn_law_detail` (~88 tokens)

Metadata for one law/regulation/interpretation record from cn_search_laws: title, category, issuing body, promulgation date, effective date, and in-force status, plus whether article-level text can be extracted via cn_law_article_text. Source: NPC National Database of Laws and Regulations.

Input parameters:

- `id` (string, required): Record id ("bbbs") from cn_search_laws.

### `cn_law_article_text` (~140 tokens)

The Chinese text of ONE specific article/provision of a law, regulation, or judicial interpretation found via cn_search_laws — not the whole document. Extracted from the official PDF the NPC database itself serves (that database has no per-article JSON text field). Returns found:false with an explanation rather than a snippet when the article cannot be located or the PDF cannot be read — this tool never fabricates text.

Input parameters:

- `article` (string|number, required): Article number (13) or the Chinese citation itself ("第十三条", "十三条之一").
- `id` (string, required): Record id ("bbbs") from cn_search_laws.

### `cn_search_admin_regulations` (~129 tokens)

Search mainland Chinese administrative regulations (行政法规) by title — a second official copy of the same regulations cn_search_laws covers, used here specifically because its detail pages carry the FULL regulation text inline as plain HTML (cn_search_laws/cn_law_article_text route through a PDF instead). Source: Ministry of Justice (司法部), National Administrative Regulations Database.

Input parameters:

- `limit` (number): Max results, 1-30 (default 10).
- `query` (string, required): Title keyword in Chinese, e.g. "公司法" (matches implementing regulations), "数据安全".

### `cn_admin_regulation_text` (~63 tokens)

Full Chinese text of one administrative regulation found via cn_search_admin_regulations, plus its revision-date history. Source: Ministry of Justice, National Administrative Regulations Database.

Input parameters:

- `law_id` (string, required): Record id ("LawID") from cn_search_admin_regulations.

### `cn_guiding_cases_list` (~91 tokens)

Index of the Supreme People's Court's official Guiding Cases (指导性案例) — binding case guidance for lower courts, numbered sequentially and released in batches. Page 1 is the newest batch. Source: court.gov.cn, 审判业务 > 指导性案例.

Input parameters:

- `page` (number): Page number, 1 = newest (default 1). Higher numbers go further back.

### `cn_guiding_case_detail` (~77 tokens)

Full text of one Supreme People's Court Guiding Case from cn_guiding_cases_list: title, issuing source, publication date, keywords (关键词), holding (裁判要点), and the full case narrative, in Chinese. Source: court.gov.cn.

Input parameters:

- `id` (string, required): Case id from cn_guiding_cases_list.

## Common questions

### What is the Cn Law MCP server?

Cn Law is an MCP server listed in the public MCP registry as io.github.pipeworx-io/cn-law. China (mainland) national law, one pack per jurisdiction (at-ris precedent: legislation AND case… This page covers its npm package (@pipeworx/mcp-cn-law).

### Is the Cn Law MCP server safe to use?

Cn Law scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Cn Law MCP server expose?

Cn Law exposes 7 tools: cn_search_laws, cn_law_detail, cn_law_article_text, cn_search_admin_regulations, cn_admin_regulation_text, and 2 more. Their descriptions and schemas cost roughly 839 tokens of context every time the server is loaded.

### Is the Cn Law MCP server still maintained?

Cn Law is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Cn Law MCP server under?

Cn Law declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Cn Law MCP server?

VerifyMCP ran 16 checks on Cn Law, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
