`kr_law_history`

Pack: kr-law · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/kr_law_history for the schema, then POST the same URL with its arguments for the data.

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.

Parameters

Name	Type	Required	Description
`mst`	string	yes	Law version id (법령일련번호) from kr_law_search’s “mst” field.
`_apiKey`	string	no	Your own OC (Open API user id) from https://open.law.go.kr/LSO/main.do, with 법령연혁 enabled under My Applications.
