LexGuard connects Claude to Korea's Open Law API, exposing 18 MCP tools that query statutes, case law, administrative rulings, and constitutional decisions. It handles natural language questions through legal_qa_tool, which automatically classifies queries across 13 legal domains and searches in parallel. You can also pull specific articles by law name and number, analyze contract clauses for legal issues, or search specialized databases like ministry interpretations and tribunal decisions. The server includes BM25 reranking, asyncio-based parallel fetching, and automatic case number detection for patterns like 2023다12345. Rate limited at 60 requests per minute per IP, it runs as a FastAPI service with both remote and Docker deployment options.
