This repository is a Model Context Protocol server that transforms 42 Korean legislative APIs into 17 accessible tools covering law, precedents, administrative rules, treaties, and tax interpretations. It provides three core capabilities: citation verification to prevent LLM hallucinations by validating legal references, impact mapping to trace how articles affect downstream precedents and regulations, and temporal diff comparison to show legal text changes between dates. The server integrates with Claude Desktop, Cursor, and other AI coding assistants.
