View your payment preferences including last used provider, recent recipients, and usage statistics.
AI agents call get_preferences to retrieve information from Africa Payments MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns user preference data without creating, modifying, deleting, or executing any operations. While it may reveal sensitive information about payment history and habits, the action itself is non-destructive read-only retrieval, making it a Read category tool with low severity.
From the tool's definition Tool name 'get_preferences' and description 'View your payment preferences' indicate a retrieval operation with no modification or side effects. The description explicitly lists read-only outputs: 'last used provider, recent recipients, and usage statistics.'
