Start asking
Your LLM calls the tools directly. Reads are immediate; anything that writes is drafted for you to confirm.
Every GA4 tool on the gateway. Read-only: nothing in your property can change.
Is this read-only?
Yes. Every GA4 tool on the gateway reads. Nerb cannot change your property configuration, and the tools are annotated read-only so your MCP client knows it too.
Do I need a service account or an API project?
No. You authorize Google once through Nerb and the gateway handles the Analytics Data API access for you.
Can I join GA4 data with my ad spend?
That is the point of putting them behind one endpoint. Connect Google Ads and GA4 and your LLM can answer questions that span both in a single conversation, rather than you reconciling two dashboards.
Which GA4 properties can it see?
Whichever ones the Google account you connect can already see. Nerb never gets more access than the person who authorized it.
Create your Nerb account, connect your first platform, and start asking from any LLM.
