🚀 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

📖 Usage Examples

Basic Account Operations

"List all my Google Ads accounts" "Show me the account details and which ones have active campaigns"

Campaign Analysis

"Show me campaign performance for account 1234567890 in the last 30 days" "Get conversion data for all campaigns in the last week" "Which campaigns have the highest cost per conversion?"

Keyword Research

"Generate keyword ideas for 'digital marketing' using account 1234567890" "Find keyword opportunities for 'AI automation' with search volume data" "Research keywords for the page https://example.com/services"

Custom GAQL Queries

"Run this GAQL query for account 1234567890: SELECT campaign.name, metrics.clicks, metrics.cost_micros FROM campaign WHERE segments.date DURING LAST_7_DAYS" "Get keyword performance data: SELECT ad_group_criterion.keyword.text, metrics.ctr, metrics.average_cpc FROM keyword_view WHERE metrics.impressions > 100"

🔍 Advanced GAQL Examples

Campaign Performance with Revenue

SELECT campaign.id, campaign.name, metrics.clicks, metrics.impressions, metrics.cost_micros, metrics.conversions, metrics.conversions_value FROM campaign WHERE segments.date DURING LAST_30_DAYS ORDER BY metrics.cost_micros DESC

Keyword Performance Analysis

SELECT campaign.name, ad_group_criterion.keyword.text, ad_group_criterion.keyword.match_type, metrics.ctr, metrics.average_cpc, metrics.quality_score FROM keyword_view WHERE segments.date DURING LAST_7_DAYS AND metrics.impressions > 100 ORDER BY metrics.conversions DESC

Device Performance Breakdown

SELECT campaign.name, segments.device, metrics.clicks, metrics.cost_micros, metrics.conversions FROM campaign WHERE segments.date DURING LAST_30_DAYS AND campaign.status = 'ENABLED'

🔒 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
# 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

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
