List all customers with filtering options
AI agents call list_customers 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 tool queries and retrieves customer data using filters. It performs no writes, deletes, executions, or financial transactions. Although customer data may be sensitive, the tool's function is purely informational retrieval, making it a Read operation. The severity is low because listing customers is a basic query with no destructive potential, though sensitivity of the data warrants basic access controls.
From the tool's definition Tool name 'list_customers' and description 'List all customers with filtering options' indicate a retrieval operation with no data modification or side effects.
