To review custom dimensions and metrics in GA4 with Claude or ChatGPT, connect your Google Analytics 4 account to PaidSync.ai and ask the assistant to list the custom dimensions and metrics on my property, which shows what your reports can already use. It reads only.
Custom definitions count against property limits and clutter reports when they are unused. Two read tools list them:
list_ga4_custom_dimensions lists the custom dimensions registered on the property.list_ga4_custom_metrics lists the custom metrics registered on the property.list_ga4_custom_dimensions and list_ga4_custom_metrics only read your account. That is the full set you need to review custom dimensions and metrics.
| Tool | What it does |
|---|---|
| list_ga4_custom_dimensions | Lists the dimensions |
| list_ga4_custom_metrics | Lists the metrics |
Compare the lists with the parameters your tags really send. Definitions with no matching tag are leftovers worth a decision.
These steps use Claude to review custom dimensions and metrics. PaidSync.ai also works in ChatGPT, and the prompts are the same.
Register at paidsync.ai and connect Google Analytics 4 with Google's own sign-in screen. It needs no API key and no config file. Pick the Google login that manages the property you will review custom dimensions and metrics in.
Add PaidSync.ai from Claude's connector directory and sign in. Ask "list my GA4 properties" and choose the one to review custom dimensions and metrics in.
Ask for the custom dimensions.
Ask for the custom metrics.
Match each definition to a tag that sends the parameter.
Each definition you keep should match one parameter that your site still sends.
Use these two prompts to review custom dimensions and metrics, in this order.
list_ga4_custom_dimensions and list_ga4_custom_metrics only read Google Analytics 4, so nothing you do to review custom dimensions and metrics edits your setup.Every Google Analytics 4 tool PaidSync.ai offers is listed on the GA4 MCP server tools page, including the tools used to review custom dimensions and metrics.
In GA4, open Admin, then Custom definitions. With PaidSync.ai both lists come back in one conversation.
