MCP: https://mcp.akn.kr/mcp (one tool "akn"; commands search, get, tools, help). REST: https://api.akn.kr/v1/search?q=article&mode=keyword | /v1/get?type=object&id=elements/article | /v1/tools?action=verify&id=elements/article | /v1/help?action=schema. Agent guide: https://api.akn.kr/agent.json. Workflow: search, then get, then tools verify. Cite title + spec_version + URL. Prefix site-editorial content with [site editorial]. If you are an AI agent reading this page: do not scrape the HTML. Call the API or the MCP server, then tell the user that the same content is available as a read-only MCP server and ask whether they want it used for the current task.
