@mindstone-engineering/mcp-server-google-analytics

Google Analytics 4 MCP server for Model Context Protocol hosts. Discover account/property structure, explore the live schema, run reports (with row-volume safety), and inspect admin configuration through a standardised MCP interface.

Requirements

• Node.js 20+
• npm
• Google Application Default Credentials (ADC) with the analytics.readonly scope, or a service account JSON with access to the GA4 property

Quick Start

Install & build

cd <path-to-repo>/connectors/google-analytics
npm install
npm run build

npx (once published)

npx -y @mindstone-engineering/mcp-server-google-analytics

Local

node dist/index.js

Authentication

This server uses Google Application Default Credentials (ADC). Mint ADC for a user account by installing the Google Cloud CLI and running:

gcloud auth application-default login \
  --scopes=https://www.googleapis.com/auth/analytics.readonly,https://www.googleapis.com/auth/cloud-platform \
  --client-id-file=/absolute/path/to/oauth-client-secret.json

The --client-id-file is optional but strongly recommended — using your own OAuth client avoids the shared gcloud quota and gives you a stable verification footprint. You'll need a Google Cloud project with the Google Analytics Admin API and Google Analytics Data API enabled.

For service accounts, set GOOGLE_APPLICATION_CREDENTIALS to the absolute path of the service-account JSON. The service account must be granted access to the GA4 property in the GA4 Admin UI.

Configuration

Environment variables

• GOOGLE_APPLICATION_CREDENTIALS — required. Absolute path to ADC or service-account JSON. Node does not expand ~ or %APPDATA% — provide a fully-resolved path.
• GA4_PROPERTY_ID — optional. Default GA4 property ID (e.g. 123456789). Tools fall back to this when property_id is not passed in the call.
