Metis Suite: the open-source email, calendar and drive client for Gmail, Outlook, Zoho and your own servers, with an AI agent, workflows and MCP

Every account you work in, one suite.

Mail, calendars and drives from Google, Microsoft, Zoho and your own servers, joined in one place. An agent, workflows and MCP work across all of it, and the agent asks before anything is sent or deleted.

Every inbox, one list.

Gmail, Outlook, Zoho Mail and IMAP together, with summaries, sorting and tracker blocking built in.

See Mail

Every calendar, one week.

Google Calendar, Outlook, Zoho Calendar and CalDAV side by side, with real editing and RSVPs.

See Calendar

Every drive, one explorer.

Google Drive, OneDrive, S3, WebDAV, FTP and SFTP, with previews in the browser and attachments saved straight from mail.

See Drive

One agent across all of it.

It searches mail, calendars and drives in one conversation, drafts replies and finds the free hour, then waits for your approval before anything is sent or deleted.

See the agent

Rules that run on their own.

When mail arrives, on a schedule or before you send: label, archive, star, mute or Bcc, with an AI question where a plain rule is not enough.

See Workflows

The suite, in your other tools.

Claude, Cursor, Codex and VS Code get the same tools as the agent, limited to the workspaces and tools you approve.

See MCP

Your accounts stay put. The suite joins them.

Metis does not ask you to move anything. It connects to the providers you already use and puts what they hold behind one search, one agent and one set of workspaces.

  • Bring the accounts you have

    Google, Microsoft and Zoho accounts, plus IMAP, CalDAV, S3, WebDAV, FTP and SFTP servers. Nothing moves, and your mail stays with your provider.

  • One search for everything

    ⌘K or Ctrl+K searches mail, events, files and people at once, with filters like from:, after: and type:file, and searches you can save.

  • One agent with the whole picture

    Ask about a thread, a meeting and a file in the same conversation, or point at any of them with @.

    See the agent

  • One workspace for the team

    Share a mailbox, calendar or drive with a workspace and keep the rest private. Roles, invites and branding cover all three.

    See workspaces

Open source. Nothing taken on trust.

Metis is AGPL-3.0. Anyone can read exactly what it does with your accounts, and every page links to the source version it runs.

  • Two-factorRequired for every account before it reaches any mail.
  • EncryptedAccount tokens and server logins are encrypted at rest.
  • AI offEvery mailbox, calendar and drive starts with AI turned off.
  • PrivateThe instance owner sees usage and health, never your mail.
  • No trackingRemote images, tracking pixels and tracking links blocked.

Questions, answered.

What is Metis Suite?

An open-source suite that joins the accounts you already have: mail, calendars and drives from Google, Microsoft, Zoho and your own IMAP, CalDAV and file servers, with an AI agent, workflows and MCP that work across all of them. It does not host your mail: that stays with your provider.

Does Metis store a copy of my mailbox?

It never mirrors your mailbox. It caches the messages you open, plus the summaries and labels it makes, so they load instantly next time. Access tokens and server logins are encrypted before they reach the database.

Which AI model does it use?

The one you bring. Metis includes no model on any plan, Cloud included: whoever runs your instance adds a key for OpenAI, Anthropic or any OpenAI-compatible endpoint, which can be a model on your own hardware. AI stays off for every mailbox, calendar and drive until you turn it on, and turning it on asks for your two-factor code.

Can the agent send mail or delete things on its own?

No. Sending, deleting, unsubscribing and every calendar, drive and workflow write wait for your approval in the chat. Reversible personal actions such as labels, snooze and read later run directly, the same way an archive does.

What license is Metis under?

AGPL-3.0-or-later. You can read every line, run it on your own servers, fork it and contribute. If your organization cannot meet the AGPL's terms, a commercial license is available.

What is the difference between Metis Cloud and self-hosting?

Both run the same release. On Metis Cloud we run an isolated instance for you, on your domain or a trymetis.email subdomain. Self-hosting runs it on a Linux server you own with Docker Compose, free under AGPL-3.0.

Is there a desktop or mobile app?

Yes: a desktop app for macOS, Windows and Linux, and an Android app, free to download. Every app works with any Metis Suite server: you enter its address the first time you open it. There is no iPhone app; the web app works in the iPhone's browser. Download the apps
