Running Clawdbot.app with a Remote Gateway

Clawdbot.app uses SSH tunneling to connect to a remote gateway. This guide shows you how to set it up.

Quick Setup

​
Step 1: Add SSH Config

Edit ~/.ssh/config and add: 
Host remote-gateway
    HostName <REMOTE_IP>          # e.g., 172.27.187.184
    User <REMOTE_USER>            # e.g., jefferson
    LocalForward 18789 127.0.0.1:18789
    IdentityFile ~/.ssh/id_rsa
Replace <REMOTE_IP> and <REMOTE_USER> with your values.

​
Step 2: Copy SSH Key

Copy your public key to the remote machine (enter password once): 
ssh-copy-id -i ~/.ssh/id_rsa <REMOTE_USER>@<REMOTE_IP>

​
Step 3: Set Gateway Token

launchctl setenv CLAWDBOT_GATEWAY_TOKEN "<your-token>"

​
Step 4: Start SSH Tunnel

ssh -N remote-gateway &

​
Step 5: Restart Clawdbot.app

# Quit Clawdbot.app (⌘Q), then reopen:
open /path/to/Clawdbot.app
The app will now connect to the remote gateway through the SSH tunnel.

​
Auto-Start Tunnel on Login

To have the SSH tunnel start automatically when you log in, create a Launch Agent.

​
Create the PLIST file

Save this as ~/Library/LaunchAgents/com.clawdbot.ssh-tunnel.plist: 
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.clawdbot.ssh-tunnel</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/bin/ssh</string>
        <string>-N</string>
        <string>remote-gateway</string>
    </array>
    <key>KeepAlive</key>
    <true/>
    <key>RunAtLoad</key>
    <true/>
</dict>
</plist>

​
Load the Launch Agent

launchctl bootstrap gui/$UID ~/Library/LaunchAgents/com.clawdbot.ssh-tunnel.plist
The tunnel will now:
  • Start automatically when you log in
  • Restart if it crashes
  • Keep running in the background

​
Troubleshooting

Check if tunnel is running: 
ps aux | grep "ssh -N remote-gateway" | grep -v grep
lsof -i :18789
Restart the tunnel: 
launchctl kickstart -k gui/$UID/com.clawdbot.ssh-tunnel
Stop the tunnel: 
launchctl bootout gui/$UID/com.clawdbot.ssh-tunnel

​
How It Works

ComponentWhat It Does
LocalForward 18789 127.0.0.1:18789Forwards local port 18789 to remote port 18789
ssh -NSSH without executing remote commands (just port forwarding)
KeepAliveAutomatically restarts tunnel if it crashes
RunAtLoadStarts tunnel when the agent loads
Clawdbot.app connects to ws://127.0.0.1:18789 on your MacBook. The SSH tunnel forwards that connection to port 18789 on the remote machine where the Gateway is running.
