## Why meta_ads_audiences_create_lookalike is rated Medium

This tool creates new advertising audiences, which is a reversible but consequential modification to Meta Ads account configuration. While audiences can typically be deleted, their creation and use can incur advertising costs and impact campaign performance. Classified as Write rather than Financial because the tool itself does not move money—it creates an asset that may subsequently be used in paid campaigns.

From the tool's own definition: "Tool name explicitly states 'create' and description states 'Creates a Lookalike Audience'. This irreversibly creates a new advertising audience in Meta Ads, modifying the account state."

## Use case

AI agents use meta_ads_audiences_create_lookalike to create or update resources in Mureo, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mureo environment.
