IMAP mailbox Overview

The IMAP mailbox MCP server connects MCP clients to any IMAP account over IMAP and provides tools for reading, searching, organizing, and drafting mail. It supports mailbox and message discovery, attachment handling, folder operations, and configurable new-message tracking. Read-only access is enabled by default, while destructive actions require explicit approval or a confirmation token. Reach for it when an agent needs mailbox access without the ability to send email.

Primary Use Cases for IMAP mailbox:
  • Search an IMAP inbox by sender, subject, body, or date
  • Review new messages without changing the human Seen state
  • Extract or save email attachments
  • Organize messages into folders with approval controls
