AI agents call get_card to retrieve information from Privacy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data about an existing virtual card without creating, modifying, deleting, or executing any operations. It is a straightforward read operation. Severity is low because exposure of card details to an unauthorized agent could enable fraud or financial compromise, but the tool itself only retrieves information; the financial risk depends on downstream misuse by the agent.
From the tool's definition Tool name is 'get_card' and description states 'Return details for a single virtual card' — a retrieval operation with no modification or side effects.
