List ad groups for a campaign.
AI agents call list_ad_groups to retrieve information from OpenAI Ads MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists ad groups associated with a campaign without modifying, deleting, or executing any operations. It is a straightforward read operation with minimal risk. The sibling tools (get_*, list_*) all follow the same read-only pattern. Low severity because data exposure is limited to metadata about ad group structure, which is typical operational information accessible to account users.
From the tool's definition Tool name 'list_ad_groups' and description 'List ad groups for a campaign' indicate a retrieval operation with no side effects. The verb 'list' is a standard read operation that queries existing data.
