List all brands
AI agents call vtex_list_brands 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 brand information from the VTEX catalog without creating, modifying, or deleting data. It is a simple data query operation with no capability to alter system state or trigger external actions. The scope is limited to read access of catalog metadata, making it low severity and low risk if misused by an AI agent.
From the tool's definition Tool name 'vtex_list_brands' with description 'List all brands' indicates a retrieval operation with no side effects. The verb 'list' is explicitly a read-only operation that queries and returns brand data without modification.
