# attach_google_negative_keyword_list

> Attach a shared negative keyword list to a campaign; an existing attachment is a no-op.

> [!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.

> A change that fails when it runs is not retried automatically. It shows on the dashboard Execution Queue.

Attach a shared negative keyword list to a campaign; an existing attachment is a no-op. Staged for dashboard approval.

**Platform:** Google Ads · **Type:** Change

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

## How to call it

* **MCP:** on `https://mcp.adsmcp.si/mcp`, run it through the `google_ads_write` tool with `{"action": "execute", "tool_name": "attach_google_negative_keyword_list", "arguments": { ... }}`, or call `attach_google_negative_keyword_list` 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/attach_google_negative_keyword_list/execute` with `Authorization: Bearer sk_live_...` and a JSON body `{"platform": "google", "arguments": { ... }}`. The arguments are listed below; they are exactly the tool's input schema.
