What it does
Lists the user-defined VARIABLES in a workspace (name, variableId, type: 'c' = constant / 'v' = Data Layer / 'jsm' = Custom JS…). Also returns each variable's `params` flattened (a constant's value, a Data Layer variable's name), which reads back its config. workspace/container: as in list_gtm_tags. Every variable is retained: limit controls only this response page (0 = as many as fit), and page_token=next_page_token retrieves the cached remainder without another Google request or credit.

How to use it
You don't call tools by name. Write what you want in ChatGPT, Claude or another assistant connected to Opus Growth, in your own words; it picks this tool when it fits.
Parameters

| container | string | Optional | · | Exact container identifier or resource name returned by the relevant container-listing tool. |
| limit | integer | Optional | 0 | Maximum number of rows returned in this response. When the result has_more flag is true, continue with next_page_token rather than assuming the list is complete. |
