Get the full content of a single email by its IMAP message ID.
AI agents call read_email to retrieve information from AOL Mail 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 without side effects. While email may contain sensitive information, the tool itself performs no destructive, executable, or state-changing operations. Classification as Read is appropriate; severity is low because retrieval alone poses minimal risk compared to the destructive tools also present on this server (delete_email, delete_all_in_folder).
From the tool's definition Tool name is 'read_email' and description states 'Get the full content of a single email by its IMAP message ID' — a straightforward retrieval operation with no modification or deletion capabilities.
