google_ads_list_accounts
AI agents call google_ads_list_accounts to retrieve information from Google Ads MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' operation retrieves account information without side effects. However, severity is elevated to medium because listing accounts in a financial advertising platform could expose sensitive campaign and spending data that an unauthorized agent might exploit for reconnaissance or data exfiltration, even though the operation itself is read-only.
From the tool's definition Tool name 'google_ads_list_accounts' indicates a retrieval operation (list) with no destructive or modifying action.
