# meta_duplicate_adset

> Duplicate a known-good ad set within the selected account, preserving complex native configuration.

[Documentation](https://www.getmcpads.com/docs) / [Sources](https://www.getmcpads.com/docs/sources) / [Meta Ads](https://www.getmcpads.com/docs/sources/meta-ads)

Duplicate a known-good ad set within the selected account, preserving complex native configuration. Always PAUSED and WITHOUT copying ads. Rename it afterwards with meta_rename_adset. Local preview by default. No automatic retry. Account ownership is checked before Meta validation or mutation.

> **Warning** This tool changes the account. It is absent from the tool list on the Free plan, and it previews by default: without `confirm: true` it describes the change and applies nothing.
