Email for humans
and machines.
A desktop email client with a CLI and MCP server. AI-powered, privacy-first, completely free and open source.
Email clients made
you choose.
GUI or terminal. Pretty or programmable. Manual or automated. Every email client picks a side. Maho Mail gives you all three — a desktop app, a CLI, and an MCP server — sharing one local database.
Everything you need.
Desktop App
A clean GUI for daily email. Keyboard shortcuts, dark mode, smart inbox. Read, compose, and organize — fast.
CLI
maho search, maho get, maho list. JSON output, Unix pipes. Script your inbox like any other tool in your stack.
MCP Server
AI agents read, search, and draft email through stdio. Connect Claude, Cursor, or any MCP-compatible tool to your inbox.
AI Built In
Summarize threads, draft replies, classify mail, translate messages. Bring your own API key — OpenAI, Anthropic, Ollama, or any OpenRouter model.
Local & Private
Everything lives on your machine. No cloud sync, no telemetry, no data leaving your device. SQLCipher encrypted at rest.
Free & Open Source
MIT licensed. No paywalls, no feature gates. Optional AI subscription via OpenRouter for those who want a managed experience.
