Mailroom

Mailroom is a hosted MCP connector that gives your AI client access to the mailbox you already use. It doesn't create a new agent inbox. Sign up, connect any IMAP/SMTP mailbox with an app password (Fastmail, iCloud, Yahoo, Zoho, your own domain, or Gmail with an app password), and you get one remote MCP URL and an API key to paste into Cursor, Claude Code, Claude Desktop (via mcp-remote), VS Code, or another MCP client that supports custom headers. Your assistant can then list folders, search and read messages, flag and move mail, and send email. Sending is deliberately two-step: send_email returns a preview, and nothing leaves your mailbox until the call is repeated with confirm=true. Mailbox credentials are encrypted at rest, API keys are stored hashed and shown once, and each account's data is isolated from other tenants. The free tier includes one mailbox and 100 MCP calls a day. Gmail one-click sign-in is coming soon; paid plans are not live yet.
