Before setting up the MCP server, you'll need:
client_secret_[long-string].json
in your project directoryNote: You'll initially get a test token with limited functionality. After testing, you can apply for production access.
2.2 Find Your Developer TokenOnce approved:

)# 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.txt3.2 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.json4.2 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:
/
or double backslashes \\
in pathsyour_developer_token_here
with your actual developer tokenClose and restart Claude Desktop to load the new configuration.
🔐 Step 5: First-Time Authentication"List all my Google Ads accounts"
After authentication, you should see:
google_ads_token.json
file created in your project directory"List all my Google Ads accounts"
"Show me the account details and which ones have active campaigns"
"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?"
"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"
"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 DESCKeyword 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 DESCDevice 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'

Enable detailed logging for troubleshooting:
# Add to server.py for debugging import logging logging.basicConfig(level=logging.DEBUG)
If you encounter issues:
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" } } }
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
