search_emails
AI agents call search_emails 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.
search_emails queries and retrieves email data based on search criteria. No side effects occur—emails are not created, modified, deleted, or executed. Although the tool description is empty, the name and server context strongly indicate a read-only search operation consistent with email retrieval functionality.
From the tool's definition Tool name 'search_emails' and server description indicating 'reading, searching...emails' via natural language. Sibling tools include read_email, read_folder, read_inbox, and list_folders—all Read category operations.
