AI agents call get_lab_details to retrieve information from Kolas without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about accredited laboratories from a public accreditation database (KOLAS/knab.go.kr). It queries and returns existing data without creating, modifying, deleting, or executing operations.
