Lulu Monitor

LuLu Monitor

AI-powered companion for LuLu Firewall on macOS.

What It Does

1. Monitors LuLu firewall alert popups
2. Extracts connection info (process, IP, port, DNS)
3. Spawns a fast AI (haiku) to analyze the connection
4. Sends Telegram notification with risk assessment
5. Provides 4 action buttons: Always Allow, Allow Once, Always Block, Block Once
6. Executes the action on LuLu when user taps a button

Auto-Execute Mode (Optional)

For reduced interruptions, enable auto-execute mode. When the AI has high confidence (known safe programs like curl, brew, node, git connecting to normal destinations), it will:

1. Automatically execute the Allow action
2. Still send a Telegram notification explaining what was auto-allowed

To enable:

# Create config.json in install directory
cat > ~/.openclaw/lulu-monitor/config.json << 'EOF'
{
  "telegramId": "YOUR_TELEGRAM_ID",
  "autoExecute": true,
  "autoExecuteAction": "allow-once"
}
EOF

Options:

• autoExecute: false (default) - all alerts require manual button press
• autoExecuteAction: "allow-once" (default, conservative) or "allow" (permanent rule)

Installation

Prerequisites

Run the check script first:

bash scripts/check-prerequisites.sh

Required:

• LuLu Firewall: brew install --cask lulu
• Node.js: brew install node
• OpenClaw Gateway: Running with Telegram channel configured
• Accessibility Permission: System Settings > Privacy > Accessibility > Enable Terminal/osascript

Gateway Configuration (Required)

The monitor calls sessions_spawn via OpenClaw's /tools/invoke HTTP API. This tool is blocked by default. Add it to the allowlist in ~/.openclaw/openclaw.json:

{
  "gateway": {
    "tools": {
      "allow": ["sessions_spawn"]
    }
  }
}

Without this, alerts will be detected but fail to forward (404 in logs).

Install

bash scripts/install.sh

This will:

1. Clone the repo to ~/.openclaw/lulu-monitor/
2. Install npm dependencies
3. Set up launchd for auto-start
4. Start the service

Verify

curl http://127.0.0.1:4441/status

Should return {"running":true,...}

Handling Callbacks

When user clicks a Telegram button, OpenClaw receives a callback like:

callback_data: lulu:allow
callback_data: lulu:allow-once
callback_data: lulu:block
callback_data: lulu:block-once

To handle it, call the local endpoint:

curl -X POST http://127.0.0.1:4441/callback \
  -H "Content-Type: application/json" \
  -d '{"action":"allow"}'  # or "block", "allow-once", "block-once"

This will:

1. Click the appropriate button on LuLu alert
2. Set Rule Scope to "endpoint"
3. Set Rule Duration to "Always" or "Process lifetime"
4. Edit the Telegram message to show result

Troubleshooting

Service not running

# Check status
launchctl list | grep lulu-monitor

# View logs
tail -f ~/.openclaw/lulu-monitor/logs/stdout.log

# Restart
launchctl unload ~/Library/LaunchAgents/com.openclaw.lulu-monitor.plist
launchctl load ~/Library/LaunchAgents/com.openclaw.lulu-monitor.plist

Accessibility permission issues

AppleScript needs permission to control LuLu. Go to: System Settings > Privacy & Security > Accessibility Enable: Terminal, iTerm, or whatever terminal you use

Alert not detected

• Ensure LuLu is running: pgrep -x LuLu
• Check if alert window exists: osascript -e 'tell application "System Events" to tell process "LuLu" to get every window'

Uninstall

bash ~/.openclaw/lulu-monitor/skill/scripts/uninstall.sh
