🚀 Quick Start

Prerequisites

Before setting up the MCP server, you'll need:

• Python 3.10+ installed
• A Google Cloud Platform account
• A Google Ads account with API access

🔧 Step 1: Google Cloud Platform Setup

1.1 Create Google Cloud Project

1. Go to Google Cloud Console
2. Create a new project:
   • Click "Select a project" → "New Project"
   • Enter project name (e.g., "Google Ads MCP")
   • Click "Create"

1.2 Enable Google Ads API

1. In your Google Cloud Console:
   • Go to "APIs & Services" → "Library"
   • Search for "Google Ads API"
   • Click on it and press "Enable"

1.3 Create OAuth 2.0 Credentials

1. Go to "APIs & Services" → "Credentials"
2. Click "+ CREATE CREDENTIALS" → "OAuth 2.0 Client ID"
3. Configure consent screen (if first time):
   • Click "Configure Consent Screen"
   • Choose "External" (unless you have Google Workspace)
   • Fill required fields:
     • App name: "Google Ads MCP"
     • User support email: Your email
     • Developer contact: Your email
   • Click "Save and Continue" through all steps
4. Create OAuth Client:
   • Application type: "Desktop application"
   • Name: "Google Ads MCP Client"
   • Click "Create"
5. Download credentials:
   • Click "Download JSON" button
   • Save file as client_secret_[long-string].json in your project directory

🔧 Step 2: Google Ads API Setup

2.1 Get Developer Token

1. Sign in to Google Ads
2. Go to Tools & Settings (wrench icon in top navigation)
3. Under "Setup", click "API Center"
4. Accept Terms of Service if prompted
5. Click "Apply for token"
6. Fill out application form:
   • Describe your use case (e.g., "MCP integration for campaign analysis")
   • Provide technical details about your implementation
7. Submit and wait for approval (usually 1-3 business days)

Note: You'll initially get a test token with limited functionality. After testing, you can apply for production access.

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

# 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

# Install dependencies
pip install -r requirements.txt

3.2 Environment Configuration

Create a .env file in your project directory:

# Copy the example file
cp .env.example .env

Edit .env with your credentials:

# Required: Google Ads API Developer Token
GOOGLE_ADS_DEVELOPER_TOKEN=your_developer_token_here

# Required: Path to OAuth credentials JSON file (downloaded from Google Cloud)
GOOGLE_ADS_OAUTH_CONFIG_PATH=/full/path/to/your/client_secret_file.json

Example .env file:

GOOGLE_ADS_DEVELOPER_TOKEN=ABCDEFG1234567890
GOOGLE_ADS_OAUTH_CONFIG_PATH=/Users/john/google-ads-mcp/client_secret_138737274875-abc123.apps.googleusercontent.com.json

🖥️ Step 4: Claude Desktop Integration

4.1 Locate Claude Configuration

Find your Claude Desktop configuration file:

macOS:

~/Library/Application Support/Claude/claude_desktop_config.json

Windows:

%APPDATA%\Claude\claude_desktop_config.json

4.2 Add MCP Server Configuration

Edit the configuration file and add your Google Ads MCP server:

{
  "mcpServers": {
    "google-ads": {
      "command": "/full/path/to/your/project/.venv/bin/python",
      "args": [
        "/full/path/to/your/project/server.py"
      ]
    }
  }
}

Real Example:

{
  "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

5.1 Trigger OAuth Flow

1. Open Claude Desktop
2. Try any Google Ads command, for example:

   "List all my Google Ads accounts"
   

5.2 Complete Authentication

1. Browser opens automatically to Google OAuth page
2. Sign in with your Google account (the one with Google Ads access)
3. Grant permissions by clicking "Allow"
4. Browser shows success page
5. Return to Claude - your command will complete automatically!

5.3 Verify Setup

After authentication, you should see:

• A google_ads_token.json file created in your project directory
• Your Google Ads accounts listed in Claude's response

🔒 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

# 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

🛠️ Troubleshooting

Authentication Issues

Issue	Symptoms	Solution
No tokens found	"Starting OAuth flow" message	✅ Normal for first-time setup - complete browser authentication
Token refresh failed	"Refreshing token failed" error	✅ Delete google_ads_token.json and re-authenticate
OAuth flow failed	Browser error or no response	Check credentials file path and internet connection
Permission denied	"Access denied" in browser	Ensure Google account has Google Ads access

Configuration Issues

Issue	Symptoms	Solution
Environment variables missing	"Environment variable not set"	Check .env file and Claude config env section
File not found	"FileNotFoundError"	Verify absolute paths in configuration
Module import errors	"ModuleNotFoundError"	Run pip install -r requirements.txt
Python path issues	"Command not found"	Use absolute path to Python executable

Claude Desktop Issues

Issue	Symptoms	Solution
Server not connecting	No Google Ads tools available	Restart Claude Desktop, check config file syntax
Invalid JSON config	Claude startup errors	Validate JSON syntax in config file
Permission errors	"Permission denied" on startup	Check file permissions and paths

API Issues

Issue	Symptoms	Solution
Invalid customer ID	"Customer not found"	Use 10-digit format without dashes: 1234567890
API quota exceeded	"Quota exceeded" error	Wait for quota reset or request increase
Invalid developer token	"Authentication failed"	Verify token in Google Ads API Center
GAQL syntax errors	"Invalid query"	Check GAQL syntax and field names

Debug Mode

Enable detailed logging for troubleshooting:

# Add to server.py for debugging
import logging
logging.basicConfig(level=logging.DEBUG)

Getting Help

If you encounter issues:

1. Check the error message carefully - it usually indicates the exact problem
2. Verify all file paths are absolute and correct
3. Ensure environment variables are properly set
4. Check Google Cloud Console for API quotas and billing
5. Restart Claude Desktop after any configuration changes

🚀 Advanced Configuration

HTTP Transport Mode

For web deployment or remote access:

# Start server in HTTP mode
python3 server.py --http

Claude Desktop config for HTTP:

{
  "mcpServers": {
    "google-ads": {
      "url": "http://127.0.0.1:8000/mcp"
    }
  }
}

Custom Token Storage

Modify token storage location in oauth/google_auth.py:

# Custom token file location
def get_token_path():
    return "/custom/secure/path/google_ads_token.json"

Manager Account Configuration

For managing multiple accounts under an MCC:

# Add to .env file
GOOGLE_ADS_LOGIN_CUSTOMER_ID=123-456-7890

📊 API Limits and Quotas

Google Ads API Quotas

• Basic access: 15,000 operations per day
• Standard access: 40,000 operations per day
• Request rate: 1,600 requests per minute per developer token

Best Practices for API Usage

1. Cache results when possible to reduce API calls
2. Use date ranges to limit data volume
3. Batch requests when supported
4. Monitor usage in Google Cloud Console
5. Implement retry logic for rate limit errors

Quota Management

# Monitor usage in Google Cloud Console
# Go to APIs & Services → Quotas
# Search for "Google Ads API" to see current usage
