Get a specific variant of a product by ID.
AI agents call tiendanube_get_product_variant 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 performs a read-only data retrieval operation. It fetches product variant information by ID, which is a standard query operation with no capability to modify data, execute commands, or trigger irreversible actions. The blast radius of misuse is minimal — an attacker could enumerate product variants but cannot modify inventory, create unauthorized transactions, or cause financial harm.
From the tool's definition Tool name includes 'get' and description states 'Get a specific variant of a product by ID' — retrieves product variant data without modification or side effects.
