Cloudflare open-sourced agentic-inbox (7.9k GitHub stars), a self-hosted AI email client running entirely on its Workers edge network.
Architecture
- Email in/out via Cloudflare Email Routing; each mailbox runs in its own Durable Object with built-in SQLite, attachments in R2 — multi-tenant isolation with zero ops.
- Native AI Email Agent built on Cloudflare Agents SDK and Workers AI with 9 email tools; it reads context and drafts replies but always requires human confirmation before sending.
- Exposes a native /mcp endpoint so external coding assistants like Cursor and Claude Code can mount it and process email across workflows.
- Ships with Cloudflare Access JWT verification for enterprise-grade access control out of the box.
Stack: React 19, React Router v7, Tailwind, TipTap, Zustand; Hono + Workers + Durable Objects (SQLite) + R2; AIChatAgent + AI SDK v6 + Workers AI. A reference implementation for Workers-based engineering and privacy-focused automated inboxes.
