AI agents call get_stock to retrieve information from Vanam Erp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves inventory data with no side effects—it is a pure read operation that queries current stock levels by item ID. The most severe risk is information disclosure of inventory levels, which is low impact in a business context. The sibling tools (list_*, search_*, lookup_*) reinforce this server's read-only query nature.
From the tool's definition Tool description indicates it "조회한다" (queries/retrieves) current stock quantity and returns itemCode, itemName, currentQty. No modification, deletion, or execution capability mentioned.
