Compatible with: Claude, Cursor and other MCP clients.

Prerequisites

Check your Python setup:

Required:

• Python 3.8 or higher
• Google Analytics 4 property with data
• Service account with Analytics Reporting API access

Step 1: Setup Google Analytics Credentials

Create Service Account in Google Cloud Console

1. Go to Google Cloud Console
2. Create or select a project:
   • New project: Click "New Project" → Enter project name → Create
   • Existing project: Select from dropdown
3. Enable the Analytics APIs:
   • Go to "APIs & Services" → "Library"
   • Search for "Google Analytics Reporting API" → Click "Enable"
   • Search for "Google Analytics Data API" → Click "Enable"
4. Create Service Account:
   • Go to "APIs & Services" → "Credentials"
   • Click "Create Credentials" → "Service Account"
   • Enter name (e.g., "ga4-mcp-server")
   • Click "Create and Continue"
   • Skip role assignment → Click "Done"
5. Download JSON Key:
   • Click your service account
   • Go to "Keys" tab → "Add Key" → "Create New Key"
   • Select "JSON" → Click "Create"
   • Save the JSON file - you'll need its path

Add Service Account to GA4

1. Get service account email:
   • Open the JSON file
   • Find the client_email field
   • Copy the email (format: ga4-mcp-server@your-project.iam.gserviceaccount.com)
2. Add to GA4 property:
   • Go to Google Analytics
   • Select your GA4 property
   • Click "Admin" (gear icon at bottom left)
   • Under "Property" → Click "Property access management"
   • Click "+" → "Add users"
   • Paste the service account email
   • Select "Viewer" role
   • Uncheck "Notify new users by email"
   • Click "Add"

Find Your GA4 Property ID

1. In Google Analytics, select your property
2. Click "Admin" (gear icon)
3. Under "Property" → Click "Property details"
4. Copy the Property ID (numeric, e.g., 123456789)
   • Note: This is different from the "Measurement ID" (starts with G-)

Test Your Setup (Optional)

Verify your credentials:

Create a test script (test_ga4.py):

Run the test:

If you see "✅ GA4 credentials working!" you're ready to proceed.

Step 2: Install the MCP Server

Choose one method:

Method A: pip install (Recommended)

MCP Configuration:

First, check your Python command:

Then use the appropriate configuration:

If python3 --version worked:

If python --version worked:

Method B: GitHub download

MCP Configuration:

Step 3: Update Configuration

Replace these placeholders in your MCP configuration:

• /path/to/your/service-account-key.json with your JSON file path
• 123456789 with your GA4 Property ID
• /full/path/to/ga4-mcp-server/ with your download path (Method B only)

Usage

Once configured, ask your MCP client questions like:

Discovery & Exploration

• And more specialized metrics

Troubleshooting

If you get "No module named ga4_mcp_server" (Method A):

If you get "executable file not found":

• Try the other Python command (python vs python3)
• Use pip3 instead of pip if needed

Permission errors:

Credentials not working:

1. Verify the JSON file path is correct and accessible
2. Check service account permissions:
   • Go to Google Cloud Console → IAM & Admin → IAM
   • Find your service account → Check permissions
3. Verify GA4 access:
   • GA4 → Admin → Property access management
   • Check for your service account email
4. Verify ID type:
