List all promotions
AI agents call vtex_list_promotions to retrieve information from MCP VTEX Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists promotions from the VTEX e-commerce platform. The 'list' operation is a standard read query with no side effects—it does not create, modify, delete, execute code, or trigger financial transactions. Even though promotions relate to commerce, merely listing them poses minimal risk; the tool cannot itself authorize or apply discounts.
From the tool's definition Tool name 'vtex_list_promotions' and description 'List all promotions' indicate a retrieval operation that queries existing promotion data without modification or execution of external operations.
