Get all email accounts configured in Apple Mail
AI agents call mail_get_accounts to retrieve information from MCP Apple Mail without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply queries and returns metadata about configured email accounts. It performs no write, delete, execute, or financial operations. While the account list could be considered sensitive metadata, the tool itself is read-only and has minimal blast radius if misused by an AI agent — at worst it discloses account information already accessible to the Mail application itself.
From the tool's definition Tool name is 'mail_get_accounts' and description states 'Get all email accounts configured in Apple Mail' — a pure retrieval operation with no modification, deletion, or execution of side effects.
