# create_meta_catalog_ad

> Create a paused Meta catalog ad chain after validation.

> [!WARNING]
>
> **Change — approval required.** Calling this tool does not change your ad account. ADSMCP checks the arguments and stages the change as a pending action. It runs only after a person approves it on the dashboard [Approvals](https://adsmcp.si/dashboard/approvals) page. Over MCP or REST you can view (`list_pending_actions`) or reject (`manage_action`) it, never approve it. `execution_mode` and similar arguments do not skip the queue.
>
> New campaigns, ad groups, ads and creatives are created paused or as drafts, so nothing starts spending when the approved change runs.
>
> A change that fails when it runs is not retried automatically. It shows on the dashboard Execution Queue.

Create a paused Meta catalog ad chain after validation.

**Platform:** Meta Ads · **Type:** Change

**Also accepted as:** `add_meta_catalog_ad`. These older names run this same tool.

## How to call it

* **MCP:** on `https://mcp.adsmcp.si/mcp`, run it through the `meta_ads_write` tool with `{"action": "execute", "tool_name": "create_meta_catalog_ad", "arguments": { ... }}`, or call `create_meta_catalog_ad` by name. `search_tools` finds it and `get_tool_schema` returns its arguments; `https://mcp.adsmcp.si/mcp/flat` lists every tool by name.
* **REST:** `POST https://mcp.adsmcp.si/api/v1/tools/create_meta_catalog_ad/execute` with `Authorization: Bearer sk_live_...` and a JSON body `{"platform": "meta", "arguments": { ... }}`. The arguments are listed below; they are exactly the tool's input schema.

      description: >-
        Create a paused Meta catalog ad chain after validation. Use this when
        you intend that change. Write tools create paused objects or wait for
        approval, and a failed spend-affecting call is not retried
        automatically.
