## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## MCP tools (3)

### `kr_law_search` (~277 tokens)

Search South Korean national statutes by title keyword (국가법령정보, Ministry of Government Legislation). Returns each matching law's id, mst (version id — pass to kr_law_article/kr_law_history), ministry, promulgation/effective dates, and whether it is the current ("현행") or a superseded ("연혁") version. BYOK: requires your own OC from open.law.go.kr (Korean real-name verification to register); pass it as _apiKey.

Input parameters:

- `_apiKey` (string): Your own OC (Open API user id) from https://open.law.go.kr/LSO/main.do. The Ministry's public demo id "test" works here for smoke-testing.
- `display` (number): Results per page, 1-100 (default 20).
- `page` (number): 1-based page number (default 1).
- `query` (string, required): Title keyword, Korean or romanized, e.g. "도로교통법" (Road Traffic Act) or "개인정보".
- `status` (string): Narrow to currently-in-force laws only ("current") or search as-is ("all", default). "historical" still returns the general list; filter client-side on the returned "status" field for superseded vers…

### `kr_law_article` (~308 tokens)

Fetch ONE article (조문) of a South Korean statute by mst (from kr_law_search) and article_no (e.g. "5" or "4-2" for 제4조의2). Never returns the whole law body. Omit article_no to get a paginated table of contents (article numbers + titles) instead. Returns the article's own text, paragraphs (항) and items (호), its own effective date (which can differ from the law's), and law-level metadata (promulgation date, effective date, ministry) kept as separate fields. BYOK: requires your own OC; pass it as _apiKey.

Input parameters:

- `_apiKey` (string): Your own OC (Open API user id) from https://open.law.go.kr/LSO/main.do. The Ministry's public demo id "test" works here for smoke-testing.
- `article_no` (string): Article number, e.g. "5", or "4-2" for a branch article (제4조의2). Omit for a table of contents.
- `display` (number): Table-of-contents mode only: entries per page, 1-200 (default 50).
- `mst` (string, required): Law version id (법령일련번호) from kr_law_search's "mst" field.
- `page` (number): Table-of-contents mode only: 1-based page number (default 1).

### `kr_law_history` (~179 tokens)

Revision history for a South Korean statute: every promulgation with its own date, promulgation number, and entry-into-force date, each as a separate historical mst you can pass to kr_law_article. Requires the caller's OC to have the 법령연혁 (law history) service separately enabled under My Applications at open.law.go.kr — if it is not, this throws a specific, actionable upstream error rather than a generic failure. BYOK: pass your OC as _apiKey.

Input parameters:

- `_apiKey` (string): Your own OC (Open API user id) from https://open.law.go.kr/LSO/main.do, with 법령연혁 enabled under My Applications.
- `mst` (string, required): Law version id (법령일련번호) from kr_law_search's "mst" field.

## Common questions

### What is the Kr Law MCP server?

Kr Law is an MCP server listed in the public MCP registry as io.github.pipeworx-io/kr-law. Korea Law MCP, South Korean national statutes via the Ministry of Government Legislation's (법제처)… This page covers its npm package (@pipeworx/mcp-kr-law).

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

Kr Law scores 81 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 Kr Law MCP server expose?

Kr Law exposes 3 tools: kr_law_search, kr_law_article, kr_law_history. Their descriptions and schemas cost roughly 764 tokens of context every time the server is loaded.

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

Kr 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 Kr Law MCP server under?

Kr 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 Kr Law MCP server?

VerifyMCP ran 16 checks on Kr 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.
