Mailbox MCPAOAuth

com.mailbox-mcp.mcp

Hosted remote server for a Microsoft 365, Gmail or IMAP mailbox you already own: read, search, draft, reply in thread, forward and file mail. It moves or flags up to 500 messages in one call, and a send leaves exactly one copy in Sent. A calendar is a separate connection, and connecting one adds diary and scheduling tools.

Read, send, file and search email in any Gmail, Microsoft 365 or IMAP mailbox, plus its calendar.
