alogin: A Go-based Security Gateway for AI Agents with Human-in-the-Loop

What is alogin?

alogin is a Go-based security gateway powered by Google Antigravity that acts as a secure conduit between AI agents and infrastructure. It's designed to solve the problem of letting Claude or other AI agents safely interact with remote servers without giving them unrestricted access.

Key Features

• Built-in MCP Server (stdio): Works natively with Claude Desktop without complex network setup
• Human-in-the-Loop (HITL): Allows definition of "Safety Rails" where destructive commands like rm or reboot require manual approval
• Multi-hop/Bastion Support: Enables AI agents to reach servers behind multiple jump hosts without exposing network complexity
• Encrypted Vault: Integrates with macOS Keychain and Linux Secret Service so AI agents never see actual passwords or keys
• Full Audit Trail: Every command executed by the AI agent is logged in a structured audit.jsonl file for accountability

Setup with Claude Desktop

Add this configuration to your claude_desktop_config.json:

"mcpServers": {
  "alogin": {
    "command": "/path/to/alogin",
    "args": ["agent", "mcp"]
  }
}

Once connected, you can ask Claude to execute commands through the secure gateway.

Technical Details

The project is written in Go for performance and includes a TUI (Terminal User Interface) for human operators. It's licensed under Apache 2.0 and the developer has 20+ years of infrastructure management experience. The tool is positioned as more than just a bridge—it's designed as a production-grade security gateway for agentic AI.
