Does confirm:true skip the ticked-account allowlist?

No. Confirm only applies a write that already passed the allowlist. An unticked account is refused server-side, including through run_tool, before any preview. Ticking is human-only. Confirm is a second human-readable step on a paid plan, not a privilege escalation.

Are new campaigns created active?

No. Campaigns are always created paused, with no option to create them active. Activating is a later write, still preview then confirm, on a paid plan. That matches how we document creates on Meta, Google, TikTok and Pinterest. Official X Ads MCP paused-create behaviour is their product, not ours; we do not ship X.

Which sources can write?

Meta Ads, Pinterest Ads, Google Ads and TikTok Ads have write tools in the catalogue. Search Console and GA4 are read only. Microsoft Advertising has no tools. There is no X Ads source. Counts are read from the catalogue on each build so a new write cannot stay unpublished on this page.

Does Claude ask twice on a write?

Often. This gateway returns a preview until confirm is true. Claude may also ask its own approval the first time it calls a tool and again for anything that writes. Those are two layers. ChatGPT and Codex can use the same URL; they are not the point of this page. The preview is the layer we operate.

Is this the same as Microsoft's open-pilot MCP?

No. Microsoft Advertising MCP is a separate official open pilot, documented as read-oriented, on Microsoft's endpoint. Our Bing row is soon: OAuth exists, tools do not. Do not pause a Microsoft campaign through this gateway. Do not treat our soon badge as their MCP.

Pause a campaign from an assistant: preview, confirm, and the Free plan

Every write tool on this gateway previews first. Without confirm set to true, the tool describes the change and applies nothing. The Free plan has no write tools: they are absent from the list and refused if called. Campaigns are always created paused. That is 1 rule on Meta, Google, TikTok and Pinterest.

What does preview then confirm mean?Link to this section

Every write tool describes the change and stops. Applying it takes a second call with confirm set to true. An assistant that picked the wrong campaign shows you the wrong campaign instead of pausing it. That is true for google_ads_update_campaign_status, meta_update_campaign_status, tiktok_update_campaign_status and pinterest_update_campaign_status.

What does the Free plan do with writes?Link to this section

Free is read only. Write tools are not announced, and calling one is refused before it reaches the platform. The refused call is not counted. 1 ad account, 1 seat, 200 tool calls per period. Upgrade when you want the preview path, not when you want a firehose.

Connect the ad platform and tick the account in the Get MCP Ads dashboard.
Paste the hosted MCP URL into your MCP client on a paid plan.
Ask the assistant to pause a named campaign without confirming yet, and read the preview.
Call the same write again with confirm set to true only after the preview is the campaign you meant.

When should you not write from an assistant?Link to this section

You are on Free. There is no write path.
The account is not ticked. The allowlist is checked server-side, including run_tool.
You need X Ads or Microsoft Advertising tools. This gateway does not ship them.
You need a GA4 or Search Console mutation. Those sources are read only here.
You wanted Meta official mcp.facebook.com/ads writes. That is Meta's server, not this preview rule.
