Get a draft with full content
AI agents call gmail.getDraft to retrieve information from Gmail 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 draft email content from the user's Gmail account. It performs a query operation with no side effects—no data is created, modified, deleted, or executed. Even though drafts may contain sensitive information, the tool itself is read-only and causes no state change.
From the tool's definition Tool name 'getDraft' and description 'Get a draft with full content' indicate data retrieval without modification. The verb 'Get' and lack of any modification, deletion, or execution language confirm read-only semantics.
