How to Connect GA4 to Claude: Setup, Prompts and Use Cases

Google Analytics 4 contains everything you need to know about your website. Traffic sources. User behavior. Conversion paths. Attribution data.

Getting answers from GA4? That's another story.

The interface fights you at every turn. Custom reports require clicks through nested menus. Segments need configuration. Comparisons mean manual setup. By the time you find the answer, you've forgotten the question.

This guide shows how to connect GA4 to Claude with the hosted GA4 MCP server, what you can ask once it's connected, and where the limits are.

"What traffic sources drove the most conversions last month?" Just ask.

What Is the Google Analytics MCP Server

The Google Analytics MCP server uses Model Context Protocol to give Claude direct access to your GA4 property.

MCP is Anthropic's open standard for connecting AI to external data sources. Instead of navigating GA4's complex interface, you ask Claude questions. Claude queries your analytics data and returns answers.

For marketers and analysts, this means GA4 insights without the GA4 learning curve.

What Data You Can Access

The Google Analytics MCP server pulls reports from the GA4 Data API and settings from the GA4 Admin API.

Traffic Data:

Sessions, users, and new users
Traffic sources: organic, paid, direct, referral, social
Campaign performance (UTM parameters)
Landing page data

User Behavior:

Views and views per session
Average engagement time
Bounce rate and engagement rate
Scroll depth and engagement metrics
Landing page and page path performance

Conversion Data:

Key events (conversions)
E-commerce transactions and revenue
Key event counts by event name
Conversion rate by source and medium

Channel and Source Views:

Key events by default channel group
Key events by source, medium and campaign
First-user vs. session traffic source comparisons

Audience Insights:

Demographics: age, gender, interests
Geographic data
Device and browser breakdown
New vs. returning users

Property Settings (Admin API):

Key events, custom dimensions and custom metrics
Audiences, channel groups and data streams
Google Ads and BigQuery links

Use Cases

Track Campaign Performance Across Sources

Marketing dollars spread across channels. Understanding which sources actually drive conversions requires constant monitoring.

Ask Claude: "Compare conversion rates by traffic source for the last 30 days. Which channels have the best ROI?"

Get a cross-channel view without building custom reports in GA4.

Understand User Behavior Patterns

GA4 captures detailed engagement data. But surfacing patterns requires knowing where to look.

"What pages have the highest engagement time but lowest conversion rate? Might be content that engages but doesn't convert."

Let Claude identify opportunities hiding in your behavior data.

Diagnose Traffic Drops

When traffic drops, you need answers fast. GA4's interface makes investigation slow.

"My organic traffic dropped 20% this week. What pages lost the most traffic? Is it a specific country or device type?"

Claude can segment the data and surface what changed.

Measure Content Performance

Content marketing success depends on understanding what resonates.

"Which blog posts drove the most key events this quarter? Which traffic sources brought those readers?"

Turn content metrics into actionable insights.

How to Set Up

Setup takes a few minutes. InsightfulPipe hosts the server, so there's nothing to install, and you connect your account with OAuth instead of creating a developer app or API keys.

Create an InsightfulPipe account (7-day trial) and connect your Google Analytics 4 account. Choose Read Only or Read + Write access, then pick the GA4 properties to include.
Copy the server URL: https://google-analytics.insightfulmcp.com/
In Claude, open Settings → Connectors, click Add custom connector, paste the URL and click Add.
Click Connect, then Authorize access in the browser.
Start a new chat, turn the connector on, and ask: "How many sessions did my site have last week?"

Using Claude Code? Run claude mcp add --transport http google-analytics-mcp https://google-analytics.insightfulmcp.com/, then type /mcp and authenticate. Steps for ChatGPT, Cursor, Gemini CLI and Codex CLI are on the Google Analytics 4 MCP server page.

Example Queries

Once connected, you can ask Claude:

"What's my total website traffic this month compared to last month?"
"Which landing pages have the highest bounce rate? Are they the same pages with the most traffic?"
"Which landing pages and traffic sources lead to the most purchases?"
"How does mobile traffic engagement compare to desktop? Are mobile users converting at the same rate?"
"Which landing pages get the most organic search sessions?"
"Which referral sources drive the highest-value users based on revenue per session?"

The more specific your question, the more useful the answer.

Common Questions

Is this Google's official GA4 MCP server?

No. Google publishes an experimental, open-source GA4 MCP server that runs locally and is read-only. InsightfulPipe runs a hosted server you connect with OAuth, which also covers GA4 Admin API tasks such as key events, custom dimensions and audiences.

Can I see real-time data?

The GA4 Data API provides reported data, which has a slight processing delay. For real-time monitoring, you'd still use GA4's real-time reports directly.

How does this compare to Looker Studio?

Looker Studio creates pre-built dashboards. The MCP server enables ad-hoc questions. Use dashboards for regular reporting, use Claude for investigation and analysis.

Can I compare multiple GA4 properties?

Yes. One Google sign-in can connect several GA4 properties, and Claude can query each one and compare them.

Is my data secure?

The server is hosted by InsightfulPipe and connects through Google OAuth. Read Only connections use Google's analytics.readonly scope, and destructive actions such as deleting a property stay off until an admin enables them.
