mcp-mail

Superhuman Mail MCP server. Connects an AI assistant to a Superhuman Mail account so it can search mail and calendar, draft and send in your voice, and handle inbox and calendar work from the chat.

Requires a Business or Enterprise plan with Ask AI enabled. The first connection opens an OAuth sign-in.

Add to your MCP client configuration:

{
  "mcpServers": {
    "Superhuman Mail": {
      "type": "http",
      "url": "https://mcp.mail.superhuman.com/mcp"
    }
  }
}

What it can do

• Search email and calendar in natural language, or filter threads by sender, label, and Split Inbox.
• Read a thread, a message, or an attachment, and see who opened mail you sent.
• Draft and revise email in your writing style, then send it, schedule it, or undo it inside the send window.
• Find a meeting time and create or update the event.
• Set reminders, mark threads done or read, star them, change labels, unsubscribe, or move a thread to trash or spam.
• Link more than one Superhuman account and choose which one is the default.

Hosted MCP server

This package connects to https://mcp.mail.superhuman.com/mcp. Clients that support a remote HTTP server can use that URL directly. OAuth still runs on first connection, and the tools above are available only for the signed-in account.
