Get a code discount by DiscountCodeNode ID. This compatibility tool replaces the older Price Rules workflow.
AI agents call get_price_rule to retrieve information from Kockatoos Shopify MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves discount/pricing information by ID. The verb 'Get' and absence of any mutation language (create, update, delete, modify) establish this as a read-only query operation. Even though the server context involves financial data (Shopify commerce), the tool itself only fetches existing discount configuration data without moving money, creating obligations, or modifying state.
From the tool's definition Tool name 'get_price_rule' and description 'Get a code discount by DiscountCodeNode ID' indicate a retrieval operation with no side effects.
