List all payment providers/gateways
AI agents call vtex_list_payment_providers 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 existing payment provider configurations. It has no side effects—it does not create, modify, delete, or execute transactions. While payment providers are sensitive infrastructure components, listing them is a read-only operation with minimal blast radius if misused by an AI agent. The tool merely enumerates available providers without triggering payments or modifications.
From the tool's definition Tool name 'vtex_list_payment_providers' and description 'List all payment providers/gateways' indicate a retrieval operation that queries and returns payment provider information without modifying or executing any financial transactions.
