Google Analytics MCP Server

An MCP server implementation for accessing Google Analytics 4 (GA4) data, built using the Model Context Protocol TypeScript SDK.

Features

Monitor user behavior metrics (session duration, bounce rate)
Flexible date range selection for all queries

Prerequisites

Node.js 20 or higher
A Google Analytics 4 property.
A Google Cloud project with the Analytics Data API enabled.
A service account with credentials to access the API.

Setup and Configuration

To use this server, you need to configure authentication with Google Analytics. This is done using a service account.

1. Enable the Google Analytics Data API

Go to the Google Cloud Console.
Select the project you want to use.
In the navigation menu, go to APIs & Services > Library.
Search for "Google Analytics Data API" and enable it.

2. Create a Service Account

In the Google Cloud Console, navigate to IAM & Admin > Service Accounts.
Click "Create Service Account".
Give the service account a name (e.g., "GA4 MCP Server").
Click "Create and Continue".
You can skip granting the service account access to the project.
Click "Done".
Find the service account you just created and click on the three dots under "Actions".
Select "Manage keys", then "Add Key" > "Create new key".
Choose JSON as the key type and click "Create". A JSON file with the credentials will be downloaded.

3. Grant Service Account Access to Google Analytics

Open Google Analytics.
Navigate to the Admin section of your GA4 property.
Under the Property column, click on Property Access Management.
Click the "+" button to add a new user.
In the "Email address" field, paste the client_email from the JSON credentials file you downloaded.
Assign the "Viewer" role. You do not need to notify the user.
Click "Add".

4. Set Environment Variables

The server requires the following environment variables:

GOOGLE_CLIENT_EMAIL: The client_email from your service account JSON file.
GOOGLE_PRIVATE_KEY: The private_key from your service account JSON file.
GA_PROPERTY_ID: Your Google Analytics 4 property ID.

You can set them in your environment or use a .env file.

export GOOGLE_CLIENT_EMAIL="your-service-account@your-project.iam.gserviceaccount.com"
export GOOGLE_PRIVATE_KEY="-----BEGIN PRIVATE KEY-----\nYOUR_PRIVATE_KEY\n-----END PRIVATE KEY-----\n"
export GA_PROPERTY_ID="your_property_id"

Security Considerations

Least Privilege: Only grant the service account the "Viewer" role in Google Analytics.
Key Management: Keep your service account key file secure and do not expose it in client-side code.
Environment Variables: Use environment variables to store sensitive information like the client email, private key, and property ID.
