@lobsterkit/lobstermail-mcp

MCP server for LobsterMail — email for AI agents. Create real @lobstermail.ai inboxes, receive email in real-time, and send email. No API keys, no human signup, no configuration.

Quick Start

Add to your MCP config (.mcp.json, claude_desktop_config.json, .cursor/mcp.json, etc.):

{
  "mcpServers": {
    "lobstermail": {
      "command": "npx",
      "args": ["-y", "@lobsterkit/lobstermail-mcp@latest"]
    }
  }
}

On first use, an account is created automatically and your token is saved to ~/.lobstermail/token.
