Search for legal terms (definitions).
AI agents call search_legal_terms to retrieve information from Korean Law MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read operation that queries and retrieves legal terminology definitions. No data is created, modified, deleted, or executed. The action has no state-changing effects and poses minimal security risk even if an AI agent misuses it—the worst outcome would be retrieval of incorrect legal definitions, not data loss or unintended consequences.
From the tool's definition Tool name 'search_legal_terms' and description 'Search for legal terms (definitions)' indicate a retrieval-only operation with no side effects. Returns definitional data from the National Law Information Center API.
