Get detailed information about a specific email
AI agents call get_email_detail to retrieve information from Google Workspace 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 email content and metadata without side effects. It performs a query operation (get) on existing Gmail data, which is characteristic of Read category tools. The blast radius is minimal since no data is created, modified, or destroyed. Severity is low as email retrieval alone poses minimal risk even if misused.
From the tool's definition Tool name 'get_email_detail' and description 'Get detailed information about a specific email' indicate a retrieval operation with no modification or deletion of data.
