Google Analytics 4

@mindstone/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), create large asynchronous exports, and inspect admin configuration through a standardised MCP interface. With writes explicitly enabled, it can also set up and change property configuration: key events, custom dimensions and metrics, audiences, channel groups, data streams, enhanced measurement, event create and edit rules, calculated metrics, annotations, attribution, Measurement Protocol secrets, product links, and data retention.

Quick Start

Install & build

cd <path-to-repo>/connectors/google-analytics

npm install npm run build

npx (once published)

npx -y @mindstone/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 \ --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.

Enabling writes

Write tools are registered but refuse to run (WRITES_DISABLED) unless GA4_ALLOW_WRITES=true. To use them, mint ADC with the edit scope instead:

gcloud auth application-default login \

--scopes=https://www.googleapis.com/auth/analytics.edit \ --client-id-file=/absolute/path/to/oauth-client-secret.json

The account (or service account) also needs the Editor role on the GA4 property. Service-account credentials request the edit scope automatically when writes are enabled; user ADC keeps whatever scope it was minted with.

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.
• GA4_ALLOW_WRITES — optional. Set to true (or 1) to allow the write tools to change GA4 configuration. Any other value, or unset, keeps the connector read-only.

Admin writes (require GA4_ALLOW_WRITES=true)

Every write is annotated readOnlyHint: false, destructiveHint: true. Archive, delete, acknowledgement, and data-retention tools also require confirm: true. Update tools change only the fields you pass (the update mask is built from them) and fail with NOTHING_TO_UPDATE if you pass none.

Explorations, saved reports, and report layouts have no Google API, so they cannot be created or changed by this connector.

Notes

• Read-only by default. Without GA4_ALLOW_WRITES=true, the only tools that create anything are ga_create_report_task and ga_create_audience_export, which materialise server-side snapshots and charge quota without modifying property configuration. The admin write tools refuse with WRITES_DISABLED before any request is sent. All of these are annotated readOnlyHint: false, destructiveHint: true, so hosts can gate them behind explicit user approval.
• Alpha endpoints. Audiences, channel groups, BigQuery lin
