Which integrations are available for this server?

Allows for the retrieval and listing of Google Ads accounts linked to specific Google Analytics 4 properties. Provides comprehensive tools for querying Google Analytics 4 (GA4) data, including property management, report execution via the Data API, and realtime data monitoring.

How do I use GA4 MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@GA4 MCP Server show me a report of active users by country for the last 30 days" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

GA4 MCP Server

A Model Context Protocol (MCP) server for Google Analytics 4 (GA4) that provides tools for querying GA4 data through the Admin API and Data API.

Features

Dual Authentication: Supports both OAuth Playground tokens and Service Account credentials
8 GA4 Tools:
- Account and property management (Admin API)
- Report execution and realtime data (Data API)
- GTM → GA4 parameter validation (cross-platform orchestration)
Compatible with Claude Desktop and other MCP-enabled clients
GTM Integration: Works with GTM MCP Server for end-to-end event validation

Installation

npm install
npm run build

Quick Start (OAuth Setup)

1. Create OAuth Credentials

Go to Google Cloud Console
Create a new project or select an existing one
Enable the Google Analytics Data API and Google Analytics Admin API
Go to Credentials → Create Credentials → OAuth client ID
Select Desktop app as the application type
Download or copy the Client ID and Client Secret

2. Run Setup Script

# Set your OAuth credentials
export GA4_CLIENT_ID="your-client-id.apps.googleusercontent.com"
export GA4_CLIENT_SECRET="your-client-secret"

# Run setup to authenticate with Google
npm run setup

This will:

Open a browser for Google login
Request read-only access to Google Analytics
Save tokens to ~/.ga4-mcp/tokens.json

3. Use the Server

Once authenticated, you can use the MCP server with Claude Desktop or other clients.

Authentication

The server supports two authentication methods, checked in this order:

1. OAuth Playground Tokens (Recommended for personal use)

Set these environment variables:

GA4_ACCESS_TOKEN - OAuth access token
GA4_REFRESH_TOKEN - OAuth refresh token
GA4_CLIENT_ID - OAuth client ID
GA4_CLIENT_SECRET - OAuth client secret

Or create ~/.ga4-mcp/tokens.json:

{
  "access_token": "your-access-token",
  "refresh_token": "your-refresh-token",
  "client_id": "your-client-id",
  "client_secret": "your-client-secret"
}

2. Service Account (Recommended for production)

Options (in priority order):

Set GA4_SERVICE_ACCOUNT_JSON environment variable with JSON string
Set GOOGLE_APPLICATION_CREDENTIALS to the JSON file path
Place JSON file at ~/.ga4-mcp/credentials.json
Place JSON file in ./Credential/ folder

Usage

Claude Desktop Configuration

Add to your Claude Desktop configuration (~/.config/claude-desktop/config.json):

{
  "mcpServers": {
    "ga4": {
      "command": "node",
      "args": ["/path/to/ga4-mcp-server/dist/index.js"],
      "env": {
        "GA4_ACCESS_TOKEN": "your-access-token",

        "GA4_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

Workflow

Extract from GTM: gtm_export_full() → Get GA4 Event tags and parameters
Validate in GA4: ga4_validate_gtm_params() → Check registration and collection
Get recommendations: Parameters not registered or not collecting data

Claude Desktop Configuration (Both Servers)

{
  "mcpServers": {
    "gtm": {
      "command": "node",
      "args": ["/path/to/gtmAgent/mcp-server/dist/index.js"],
      "env": {}
    },
    "ga4": {
      "command": "node",
      "args": ["/path/to/ga4-mcp-server/dist/index.js"],
      "env": {
        "GA4_ACCESS_TOKEN": "your-access-token",
        "GA4_REFRESH_TOKEN": "your-refresh-token",
        "GA4_CLIENT_ID": "your-client-id",
        "GA4_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

API Call Efficiency

Scenario	Traditional	Optimized	Reduction
5 events × 21 params	105 calls	22 calls	79%
14 events × 32 params	448 calls	33 calls	93%

The validation tool queries metadata once, then makes one API call per unique parameter instead of per event-parameter combination.
