Ministry of Government Legislation Open API-based MCP server + CLI. Available directly on Claude Desktop, Cursor, Windsurf, Zed, Claude.ai, and more. - : In addition to confirming the existence of the provision, as in Article 750 of the Civil Act (Contract Termination), ** is detected as [CONTENT_MISMATCH]. Previously, only Article 750 was passed if it existed, but now the cited provision title matches the actual text (LexDiff citation-content-matcher transplant — common substring + bigram Jaccard after normalization). The same applies to legal_analysis (mode=verify_citations) - : When the Ministry of Government Legislation returns a location.assign JS redirect page instead of API data from cloud IP (GCP/AWS/Fly), it parses obfuscated URLs and automatically bypasses to the token URL (maximum 3 hops, retries the original at 404 token URLs). No-op on local/registered IPs — a cloud environment defense layer that cannot be penetrated even with Referer injection (v4.0.9) search_law is scheduled to be implemented (target=eflaw) and is included in the results by performing a supplementary search. - : Displays name changes between promulgation and implementation using new and old name mapping, similar to the Act on the Promotion of Data-Based Administration → the Act on Promotion of Artificial Intelligence and Data-Based Administration (effective 2026-08-28) — Solved the issue where LLMs misidentified as "No Law" when searching for new names - : If there are amendments pending implementation in the searched current laws, information on the enforcement date, promulgation number, and MST of the upcoming version - : Separate notifications are provided for laws that have been promulgated but have not yet been enforced, so there are zero current search results (including warnings indicating no effect). - : Fixes zod at ^4 — New installers interpret zod 3.x and use z.
