List all categories in a tree structure
AI agents call vtex_list_categories 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 queries and returns category data in hierarchical form. It performs a pure read operation—retrieving existing catalog information without creating, modifying, deleting, or executing any actions. The blast radius of misuse is minimal, as an agent querying categories poses no risk to inventory, orders, payments, or system integrity.
From the tool's definition Tool name 'list_categories' and description 'List all categories in a tree structure' indicate a retrieval operation with no data modification or side effects.
