List product reviews with filters
AI agents call vtex_list_reviews 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 filters product reviews, a read-only operation with no side effects. It poses minimal security risk as it only accesses existing data. Even if an AI agent misuses it by listing all reviews, the impact is limited to information disclosure of already-public review data.
