antigravity-daemon

A daemon that enables CodexBar's Antigravity provider to work without the Antigravity app running.

Overview

CodexBar detects the Antigravity language server by looking for language_server_macos processes. This daemon mimics the language server endpoints that CodexBar expects, allowing you to use Antigravity's AI capabilities through CodexBar even when the Antigravity app is not open.

How It Works

1. Token Extraction: Reads the OAuth refresh token from Antigravity's SQLite database (~/Library/Application Support/Antigravity/User/globalStorage/state.vscdb)
2. OAuth Refresh: Uses the refresh token to obtain valid access tokens from Google's OAuth service
3. Quota Proxy: Proxies requests to cloudcode-pa.googleapis.com to fetch your quota and model information
4. Endpoint Mimicry: Provides the endpoints CodexBar expects:
   • /exa.language_server_pb.LanguageServerService/GetUserStatus
   • /exa.language_server_pb.LanguageServerService/GetCommandModelConfigs
   • /exa.language_server_pb.LanguageServerService/GetUnleashData
   • /v1internal:retrieveUserQuota

Requirements

• Python 3.7+
• macOS
• CodexBar installed
• Antigravity app installed (duh)

Installation

# Clone the repository
git clone https://github.com/mdgld/antigravity-daemon.git
cd antigravity-daemon

Usage

Running the Daemon

python3 language_server_macos_arm.py [--port PORT]

The default port is 54399. The daemon will:

1. Automatically generate TLS certificates
2. Extract your refresh token from Antigravity's database
3. Start listening for CodexBar connections

Running as a LaunchAgent (Recommended)

To run automatically on login:

# Create the LaunchAgent directory if it doesn't exist
mkdir -p ~/Library/LaunchAgents

# Create the plist file
cat > ~/Library/LaunchAgents/com.user.antigravity-daemon.plist << 'EOF'
<?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.user.antigravity-daemon</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/bin/python3</string>
        <string>/Users/matthewgold/code/antigravity/language_server_macos_arm.py</string>
        <string>--port</string>
        <string>54399</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>StandardOutPath</key>
    <string>/tmp/antigravity-daemon.log</string>
    <key>StandardErrorPath</key>
    <string>/tmp/antigravity-daemon.log</string>
</dict>
</plist>
EOF

# Load the LaunchAgent
launchctl load ~/Library/LaunchAgents/com.user.antigravity-daemon.plist

CodexBar Configuration

Ensure your ~/.codexbar/config.json has the Antigravity provider configured. The daemon will automatically pick up any planLabelOverride setting from your provider config.

Configuration

Plan Label Override

You can customize the plan name displayed in CodexBar by adding a planLabelOverride to your CodexBar provider configuration:

{
  "providers": [
    {
      "id": "antigravity",
      "planLabelOverride": "My Custom Plan"
    }
  ]
}

Custom Port

If you need to use a different port:

python3 language_server_macos_arm.py --port 54398

Logs

Logs are written to stdout. When running as a LaunchAgent, check:

tail -f /tmp/antigravity-daemon.log

Troubleshooting

Token Not Found

If you see "oauthToken not found in globalStorage", make sure:

1. Antigravity app has been launched at least once
2. You are logged into Antigravity

GlobalStorage Not Found

Ensure the path exists:

ls ~/Library/Application\ Support/Antigravity/User/globalStorage/

Port Already in Use

Find and kill the existing process:

lsof -i :54399
kill <PID>

Security

• TLS certificates are generated locally and stored in /tmp/
• Refresh tokens are read from Antigravity's local database
• No credentials are stored by this daemon (tokens are cached in memory only)
