Part of the Korean Law Search MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call article_amendment_diff to retrieve information from Korean Law Search without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though article_amendment_diff only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Compare how a specific article changed between two law versions (조문 신구대조). Use MST values from law_amendment_summary to compare article text across revisions. Args: mst_old: MST of the older version (법령일련번호, from law_amendment_summary) mst_new: MST of the newer version article: Article number (e.g., 52 for 제52조) article_branch: Branch number (e.g., 2 for 제52조의2, default 0) oc: Optional OC override type: Response format - "JSON" (default), "XML", or "HTML" Returns: Side-by-side comparison with line-level diff Examples: >>> article_amendment_diff(mst_old="269000", mst_new="273000", article=52) . It is categorised as a Read tool in the Korean Law Search MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for article_amendment_diff. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Korean Law Search MCP server.
article_amendment_diff is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the article_amendment_diff rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the Intercept policy for article_amendment_diff. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
article_amendment_diff is provided by the Korean Law Search MCP server (rabqatab/lexlink-ko-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
