Retrieve a specific card for a customer
AI agents call retrieve_customer_card to retrieve information from Omise MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves card information for a customer. While the data retrieved is sensitive (payment card details), the tool itself performs no destructive, financial, or executable operations.
From the tool's definition Tool name and description explicitly state 'Retrieve a specific card for a customer' — a query operation with no modification or side effects.
