🚀 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

Go to Google Cloud Console
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

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

Go to "APIs & Services" → "Credentials"
Click "+ CREATE CREDENTIALS" → "OAuth 2.0 Client ID"
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
Create OAuth Client:
- Application type: "Desktop application"
- Name: "Google Analytics MCP Client"
- Click "Create"
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

Sign in to Google Analytics
Verify you have access to GA4 properties
Note your property IDs (found in GA4 Admin → Property Settings)
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

Open Claude Desktop
Try any Google Analytics command, for example:
```
"List all my Google Analytics properties"
```

5.2 Complete Authentication

Browser opens automatically to Google OAuth page
Sign in with your Google account (the one with Analytics access)
Grant permissions by clicking "Allow"
Browser shows success page
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

Use environment variables instead of .env files in production
Implement rate limiting to respect API quotas
Monitor API usage in Google Cloud Console
Secure token storage with proper access controls
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_analytics_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 Analytics 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 Analytics 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 property ID	"Property not found"	Use numeric format: `421301275`
API quota exceeded	"Quota exceeded" error	Wait for quota reset or request increase
Invalid date format	"Invalid date"	Use YYYY-MM-DD format: `2025-01-31`
No data returned	Empty results	Check date range and property access

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"

Request rate: 10 queries per second per project

Best Practices for API Usage

Cache results when possible to reduce API calls
Use appropriate date ranges to limit data volume
Batch requests when supported
Monitor usage in Google Cloud Console
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
