List available payment providers configured in the store (extracted from /store).
AI agents call tiendanube_list_payment_providers to retrieve information from Tienda Nube MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves configuration data about payment providers without any side effects. It is a read-only query operation that returns stored information. The blast radius of misuse is minimal—an attacker would only gain visibility into which payment methods are enabled, not access to payment credentials, transaction data, or the ability to process payments.
From the tool's definition Tool name contains 'list' and description states 'List available payment providers configured in the store'. No modification, deletion, or execution of external operations occurs.
