GET ORDER CUSTOM FIELDS - Retrieve all custom fields for a specific order.
AI agents call tiendanube_get_order_custom_fields 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 only retrieves custom field data from an existing order. It performs a read-only query operation without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal: an unauthorized agent could read order metadata, potentially exposing customer information, but cannot alter order state, trigger financial transactions, or execute arbitrary operations.
From the tool's definition Tool name contains 'get' and description states 'Retrieve all custom fields for a specific order' — pure data retrieval with no modification or side effects.
