### 2.2 Find Your Developer Token
Once approved:
1. **Return to API Center in Google Ads**
2. **Copy your Developer Token** (format: `XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX`)
## 🔧 Step 3: Installation & Setup
### 3.1 Clone and Install
```bash
# Clone the repository
git clone https://github.com/yourusername/google-ads-mcp-server.git
cd google-ads-mcp-server
# Create virtual environment (recommended)
python3 -m venv .venv
source .venv/bin/activate # On Windows: .venv\Scripts\activate

```json
{
"mcpServers": {
"google-ads": {
"command": "/full/path/to/your/project/.venv/bin/python",
"args": [
"/full/path/to/your/project/server.py"
]
}
}
}
```
**Real Example:**
```json
{
"mcpServers": {
"google-ads": {
"command": "/Users/marble-dev-01/workspace/google_ads_with_fastmcp/.venv/bin/python",
"args": [
"/Users/marble-dev-01/workspace/google_ads_with_fastmcp/server.py"
]
}
}
}
```
**Important:**
- Use **absolute paths** for all file locations
- On Windows, use forward slashes `/` or double backslashes `\\` in paths
- Replace `your_developer_token_here` with your actual developer token
### 4.3 Restart Claude Desktop
Close and restart Claude Desktop to load the new configuration.
## 🔐 Step 5: First-Time Authentication

## 🔒 Security & Best Practices
### File Security
- ✅ **Credential files are gitignored** - Never committed to version control
- ✅ **Local token storage** - Tokens stored in `google_ads_token.json` locally
- ✅ **Environment variables** - Sensitive data in `.env` file
- ✅ **Automatic refresh** - Minimal token exposure time
### Recommended File Permissions
```bash
# Set secure permissions for sensitive files
chmod 600 .env
chmod 600 google_ads_token.json
chmod 600 client_secret_*.json
```
### Production Considerations
1. **Use environment variables** instead of `.env` files in production
2. **Implement rate limiting** to respect API quotas
3. **Monitor API usage** in Google Cloud Console
4. **Secure token storage** with proper access controls
5. **Regular token rotation** for enhanced security
