Google Analytics 4 Data API MCP

A Model Context Protocol (MCP) server for accessing Google Analytics 4 reporting data.

Installation

npm install -g mcp-ga4-data

Or use it directly via npx:

npx mcp-ga4-data

Requirements

1. A Google Cloud project with the Google Analytics Data API enabled
2. A service account with appropriate permissions for Google Analytics
3. A credentials.json file for the service account

Usage with Claude (or other MCP Clients)

This MCP is designed to work with Claude or other MCP Clients. To use it with Claude, create a claude-mcp-config.json file with the following content:

{
  "mcpServers": {
    "google-analytics-data": {
      "command": "npx",
      "args": ["mcp-ga4-data"],
      "cwd": "/tmp",
      "env": {
        "GOOGLE_APPLICATION_CREDENTIALS": "/path/to/your/credentials.json"
      }
    }
  }
}

Replace /path/to/your/credentials.json with the actual path to your Google service account credentials file.

Configuration

You need to provide the path to your Google service account credentials file. There are two ways to do this:

Option 1: Environment Variable

Set the GOOGLE_APPLICATION_CREDENTIALS environment variable directly:

export GOOGLE_APPLICATION_CREDENTIALS=path/to/your/credentials.json

Option 2: .env File (Optional)

Alternatively, you can create a .env file in the directory where you want to use the MCP with the following content:

GOOGLE_APPLICATION_CREDENTIALS=path/to/your/credentials.json

Note: The .env file is completely optional. The package will work fine with just the environment variable set.
