Integration details

Description

Connect supported IMAP mailboxes to your agent with access limited to the mailboxes you authorize. Read incoming email events, message details and plain-text bodies, together with saved owner preferences or connector defaults identified by source and revision. Your agent performs the analysis. An optional tool records a local decision and stops remaining local delivery and retries for that event; requests already sent may still complete. inboxmcp does not classify or rank email, send replies, delete or move messages, or mark source messages as read. Attachments are not analyzed. This MCP plugin does not provide native background subscriptions or user notifications. An inboxmcp account and a supported mailbox connection are required. Currently in limited public beta.
