List ads inside a campaign, ad set, or ad account.
AI agents call list_ads to retrieve information from Claude Meta without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries existing ads from a Meta Ads account without creating, modifying, or deleting any data. It is a straightforward read operation that returns information about ads. The potential blast radius is minimal—even if an AI agent calls this repeatedly, it only queries data that is already public or authorized to the account.
From the tool's definition Tool name is 'list_ads' and description states 'List ads inside a campaign, ad set, or ad account.' The verb 'list' indicates data retrieval with no side effects.
