To turn on built in variables in Google Tag Manager with Claude or ChatGPT, connect your Google Tag Manager account to PaidSync.ai and ask the assistant to turn on built in variables, which makes values like click URL and form ID usable. It changes the workspace, so read the request before you approve.
Many triggers use built in variables that are off by default. A write tool switches them on:
list_gtm_builtin_variables shows which are on now.enable_gtm_builtin_variables enables built in variables such as click URL, form ID and page path.list_gtm_builtin_variables only reads your account. enable_gtm_builtin_variables changes it. That is the full set you need to turn on built in variables.
| Tool | What it does |
|---|---|
| list_gtm_builtin_variables | Shows what is on |
| enable_gtm_builtin_variables | Enables them |
Only enable what you need. Extra variables clutter the workspace.
These steps use Claude to turn on built in variables. PaidSync.ai also works in ChatGPT, and the prompts are the same.
Create a free account at paidsync.ai and approve Google Tag Manager on Google's own sign-in screen. You do not need an API key or any config file, only a login with access to the container where you will turn on built in variables.
Install PaidSync.ai from Claude's connector directory and sign in. Ask "list my Google Tag Manager containers" and select the one to turn on built in variables in.
List the enabled built in variables.
Ask for the click or form variables your trigger uses.
Confirm they are enabled.
The new variables appear in the list and in preview mode.
Use these two prompts to turn on built in variables, in this order.
list_gtm_builtin_variables only reads Google Tag Manager, so the lookup before you turn on built in variables changes nothing.enable_gtm_builtin_variables applies on the first call without a dry run, so when you turn on built in variables, your assistant's approval prompt is the check before it runs.enable_gtm_builtin_variables runs to turn on built in variables.Every Google Tag Manager tool PaidSync.ai offers is listed on the Google Tag Manager MCP server tools page, including the tools used to turn on built in variables.
In Tag Manager, open Variables, then Configure. With PaidSync.ai you name the variables and the assistant enables them.
Only a few are. Click and form variables usually need to be enabled.
Yes. PaidSync.ai connects Google Tag Manager to ChatGPT and to Claude, and the same tools run in both, so you can ask it to turn on built in variables the same way you would in Claude.
