🚀 Quick Start

Prerequisites

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

• Python 3.10+ installed
• A Google Cloud Platform account
• A Google Analytics 4 property with data 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 Analytics MCP")
   • Click "Create"

1.2 Enable Google Analytics APIs

1. In your Google Cloud Console:
   • Go to "APIs & Services" → "Library"
   • Search for "Google Analytics Data API" and enable it

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 Analytics MCP"
     • User support email: Your email
     • Developer contact: Your email
   • Add scopes:
     • https://www.googleapis.com/auth/analytics
     • https://www.googleapis.com/auth/analytics.readonly
   • Click "Save and Continue" through all steps
4. Create OAuth Client:
   • Application type: "Desktop application"
   • Name: "Google Analytics 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 Analytics Access

2.1 Ensure Analytics Access

1. Sign in to Google Analytics
2. Verify you have access to GA4 properties
3. Note your property IDs (found in GA4 Admin → Property Settings)
4. Ensure your Google account has at least Viewer access to the properties you want to query

🔧 Step 3: Installation & Setup

3.1 Clone and Install

# Clone the repository
git clone https://github.com/yourusername/google-analytics-mcp-server.git
cd google-analytics-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: Path to OAuth credentials JSON file (downloaded from Google Cloud)
GOOGLE_ANALYTICS_OAUTH_CONFIG_PATH=/full/path/to/your/client_secret_file.json

Example .env file:

GOOGLE_ANALYTICS_OAUTH_CONFIG_PATH=/Users/john/google-analytics-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 Analytics MCP server:

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

Real Example:

{
  "mcpServers": {
    "google-analytics": {
      "command": "/Users/marble-dev-01/workspace/google_analytics_mcp/.venv/bin/python",
      "args": [
        "/Users/marble-dev-01/workspace/google_analytics_mcp/server.py"
      ]
    }
  }
}

Important:

• Use absolute paths for all file locations
• On Windows, use forward slashes / or double backslashes \\ in paths

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 Analytics command, for example:

   "List all my Google Analytics properties"
   

5.2 Complete Authentication

1. Browser opens automatically to Google OAuth page
2. Sign in with your Google account (the one with Analytics 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_analytics_token.json file created in your project directory
• Your Google Analytics properties 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_analytics_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_analytics_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

Configuration Issues

Claude Desktop Issues

API Issues

Debug Mode

Enable detailed logging for troubleshooting:

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

🚀 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-analytics": {
      "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_analytics_token.json"

📊 API Limits and Quotas

Google Analytics API Quotas

• Core Reporting API: 100,000 requests per day per project
• Realtime API: 10,000 requests per day per project
• Request rate: 10 queries per second per project

Best Practices for API Usage

1. Cache results when possible to reduce API calls
2. Use appropriate 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 Analytics" to see current usage
