mailbox

Self-hosted REST API and web UI for all your mailboxes (IMAP, JMAP, POP3, Gmail, Microsoft 365, Outlook.com), with a Python client and an MCP server so AI agents read, sort, draft and send mail, only within the rights, folders and send limits you grant. Change feed, signed webhooks, audit.

Installation

MCP client config (paste into mcp.json)

{
  "mcpServers": {
    "benethos-mailbox-mcp": {
      "command": "npx",
      "args": [
        "benethos-mailbox-mcp"
      ]
    }
  }
}

Agent install prompt

Copy and paste into Cursor / Claude / other agents to install this MCP for you

Please read this MCP repository and install it into my current environment:
https://github.com/benethos-hub/mailbox

Known working client config (can write into mcp.json):
{
  "mcpServers": {
    "benethos-mailbox-mcp": {
      "command": "npx",
      "args": [
        "benethos-mailbox-mcp"
      ]
    }
  }
}

Please: 1) check README for deps and env vars; 2) write config for my client; 3) if secrets are missing, tell me what to fill — do not invent values.
