Preview first, applied after you approve

What it does

Adds AND removes text assets in an existing Performance Max asset group. headlines/long_headlines/descriptions add new text. remove_resource_names: comma-separated `resource_name` values from get_pmax_assets — those assets are unlinked from the group. Both in one call REPLACE an asset atomically (needed when a field is already at its maximum, such as 15 headlines). Google minimums are enforced before anything is sent: 3 headlines, 1 long headline, 2 descriptions, 1 business name. confirm=false → dry-run.

MCP: update_pmax_assets

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.

Because this tool changes your account, your assistant first shows a preview of exactly what will change. Nothing is applied until you say yes, and every applied change is written to your audit log.
