AI agents call google_ads.ad_groups.list to retrieve information from Ads without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries ad group data from Google Ads without any side effects. It presents bid information, status, parent campaign, and metrics over a date range, functioning as a read-only wrapper over GAQL (Google Ads Query Language). The optional filtering to a single campaign is still a retrieval operation. No data is created, modified, deleted, or used to trigger financial transactions.
From the tool's definition Tool name contains 'list' and description states 'List Google Ads ad groups' with retrieval of metrics and status information. No modification, deletion, or execution of external operations occurs.
