List all draft emails
AI agents call list_drafts to retrieve information from Enhanced 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 draft emails from Gmail. It has no side effects, does not modify data, does not execute external code or operations, and does not involve financial transactions. The only potential concern is access to email content, but the operation itself is non-destructive query/retrieval, fitting the 'Read' category.
From the tool's definition Tool name 'list_drafts' and description 'List all draft emails' indicate a retrieval operation that queries existing draft email data without modifying, deleting, or executing any actions.
