08FAQFAQ
Before connecting GA4 to ChatGPT, marketers usually ask about MCP, Universal Analytics, several properties, realtime data, Claude, other Google MCPs and Data Studio. The last three answers help when numbers look off.
What is MCP in data analytics?
MCP (Model Context Protocol) is an open standard that lets an AI assistant such as ChatGPT call tools in other apps. For analytics, an MCP server such as Porter's turns your question into a GA4 report request and returns the rows. ChatGPT then answers from your live GA4 data instead of a pasted export.
Is Google Analytics discontinued, and does this work with Universal Analytics?
No. Google Analytics continues as GA4, which replaced Universal Analytics, and Google ended access to UA data starting the week of July 1, 2024 (Google's notice that GA4 replaced Universal Analytics). Porter reads your GA4 properties, so ChatGPT answers from the data GA4 collects.
Can I connect several GA4 properties as an agency?
Yes. Select several GA4 properties when you connect Porter, then ask ChatGPT to compare them in one table or one summary. Each property is billed as one account, while one Porter subscription covers every client property you manage, with unlimited users on paid plans.
Can ChatGPT read GA4 realtime data?
Yes, in chat. ChatGPT can run a GA4 realtime report through Porter on the last minutes of activity. For example, active users by page or by country right now. Realtime data isn't saved in Porter reports or dashboards, so ask ChatGPT whenever you need a fresh look during a launch or campaign.
Can I use Porter in Claude too?
Yes. Porter's MCP URL, the same one behind the Google Analytics 4 connector for ChatGPT, also works in Claude as a custom connector, with the same Porter account and properties. See Porter's Google Analytics 4 connector for Claude for the Claude setup and what it covers.
Is there a Google Ads or Search Console MCP for ChatGPT too?
Yes. Porter also connects Google Ads and Google Search Console to ChatGPT the same way it connects GA4, with the same MCP URL. Add the Google Ads connector for ChatGPT or the Search Console connector in Porter, then ask about them next to GA4 in one chat.
I already send GA4 to Looker Studio with Porter. Do I need to reconnect for ChatGPT?
No. A GA4 property connected in Porter feeds every Porter destination at no extra cost. That includes both ChatGPT and the GA4 connector for Data Studio (formerly Looker Studio). Just add Porter's MCP URL to ChatGPT as a custom MCP server, then ask your first question.
Troubleshooting
Why don't ChatGPT's numbers match the GA4 interface?
ChatGPT's GA4 numbers through Porter differ from the interface for a few reasons. Users don't add up across days, so ask for the period total, and recent days are still processing. Days with no data are missing rather than 0, rates come back as fractions (0.45 means 45%), and dates follow your property's time zone.
Why are some GA4 rows missing, "(other)" or "unknown"?
GA4 hides rows under its privacy thresholds, such as age, gender, interests and small segments, and you can't turn that off (Google's note on GA4 data thresholds). Very large reports can be sampled or roll rare values into "(other)" (Google's note on GA4 data sampling). Use longer date ranges for thresholded data, but fewer dimensions or shorter ranges for large reports.
Why does a GA4 question fail or return no data?
A GA4 question fails through Porter when it asks for more than 9 dimensions or 12 metrics. It also fails when it mixes item and order fields, or asks for Conversions and Key events together. No data usually means either your Google account lacks Viewer access, or the property wasn't ticked at sign-in. Reconnect GA4 in Porter, then ask ChatGPT again.
