AI agents call diff_article_versions to retrieve information from Taxlaw Nts without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only tool that analyzes and returns textual differences between two versions of legal articles from the Korean tax law database. The core function is to retrieve and display diffs with markers (【삭제】【신설】) and contextual information. No data is written, deleted, or executed — it only searches and displays comparative information from existing legal records.
From the tool's definition Tool performs word-level machine diff (기계 대조) and retrieves/returns only changed hunks between two versions of tax law articles.

It is categorised as a Read tool in the Taxlaw Nts MCP Server, which means it retrieves data without modifying state.
Register the Taxlaw Nts MCP server in PolicyLayer and add a rule for diff_article_versions: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Taxlaw Nts. Nothing to install.
