A self-hosted MCP server that plugs Claude Code into any IMAP/SMTP inbox. 15 tools covering what you actually need for inbox automation: list/search across folders, fetch full messages and attachments, draft and revise replies, send, move, copy, flag, delete, and folder operations.
Multi-account is built in. Every tool call takes an account argument, so a single instance speaks to Gmail, Fastmail, Proton via Bridge, iCloud, Outlook 365, and generic IMAP servers at once. I run three accounts on mine.
Self-hosted means credentials live in your .env and never leave it. The only outbound traffic is the TLS connection to your mail provider. No telemetry, no SaaS proxy in the middle.
Works with Claude Code over stdio. Tested daily on Hostinger and Gmail. mail-tester.com scores 10/10 on the SMTP setup (SPF, DKIM, DMARC all pass) when the sending domain is configured properly.
$49 one-time, commercial license, perpetual updates, same-day refund if it doesn't fit your setup.
