Get all sales with optional filters (date range, email, pagination)
AI agents call get_sales to retrieve information from Gumroad MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries sales data without side effects. It filters but does not create, modify, delete, or move money. The filters (date range, email, pagination) are all query parameters for data retrieval. Classified as Read with low severity because access to sales data poses minimal risk if misused by an AI agent—it cannot alter records or trigger financial actions.
From the tool's definition Tool name is 'get_sales' and description states 'Get all sales with optional filters (date range, email, pagination)' — a retrieval operation with no modification, deletion, or financial transaction capability.
