Get all subscribers for a specific Gumroad product
AI agents call get_subscribers 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 queries and retrieves subscriber data from Gumroad. It performs a read-only operation (GET) that returns information about existing subscribers without creating, modifying, deleting, or moving money. The blast radius of misuse is limited to unauthorized access to subscriber list information, which is a low-severity information disclosure risk rather than a destructive, financial, or system-altering action.
From the tool's definition Tool name 'get_subscribers' and description 'Get all subscribers for a specific Gumroad product' indicate a retrieval operation with no modification, deletion, or financial action.
