Maho Core Feature Showcase
Core Architecture

One database. Three interfaces.

Maho Mail combines a desktop app, CLI, and MCP server into a single client. Built with Tauri v2 and React 19 on top of a shared SQLCipher-encrypted SQLite database, it gives you GUI, scripting, and agentic workflows simultaneously.

Three Interfaces

Control your inbox your way.

Tauri v2 + React 19

Desktop Application (GUI)

A clean, keyboard-driven interface built on React 19. Fast searching, smart thread nesting, and instant compose with offline-first capabilities.

CLI Reference

Command-Line Interface (CLI)

Script your email workflows. Output mail data in clean JSON, pipe to tools like jq, grep, or fzf. Complete unix integration.

$ maho search "from:alex invoice" [ { "id": "msg_9f2a81", "subject": "Invoice May 2026", "date": "2026-05-15" } ] $ maho get msg_9f2a81 --body-text
AI Agentic Integration

Model Context Protocol (MCP) Server

Direct stdio-based integration with Claude Desktop, Cursor, or autonomous agents. Let AI agents securely search, draft, or organize your emails locally.
