What is the Fluxmail MCP server?

Read, search, draft, send, and organize email through Gmail and IMAP/SMTP mailboxes. That is what the fluxmail mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.

The short version

Fluxmail is self-hosted email infrastructure for agents and apps. It connects to Gmail, Microsoft 365, Outlook.com, and IMAP/SMTP mailboxes. Agents use MCP, apps and backend workflows use the versioned REST API, and operators use the CLI to connect mailboxes, manage access, and run the service.

  • 📬 Connect Gmail, Google Workspace, Microsoft 365, Outlook.com, and IMAP/SMTP mailboxes to one instance
  • 🤖 Give agents MCP tools to list, search, read, draft, reply, forward, send, schedule, and organize email
  • 🔌 Use the same mailbox operations from the versioned REST API and CLI
  • 🧵 Fetch complete messages and threads, work across several mailboxes, and download attachments
  • 🗂️ Mark mail as read, star or archive it, move it between folders, send it to Trash, and manage Gmail labels or Outlook categories
  • 🔐 Limit each client to selected mailboxes and actions with permission profiles or custom policies

Getting it running

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

How it compares

Plenty of team communication servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. It is maintained by churichard; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Things to watch

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
