RECOMMENDED RULE

The rule that runs create_openai_ads_ad safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Hermoso, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_openai_ads_ad, this is the rule to start with:

create_openai_ads_ad Rate-limited

create_openai_ads_ad stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about create_openai_ads_ad

What does the create_openai_ads_ad tool do? +

Create the actual AD inside a ChatGPT Ads ad group — the object that carries the creative; a campaign or ad group alone shows nothing at all. The creative is a TEXT + IMAGE CARD: a title of 3–50 characters, body copy of 100 characters maximum, one landing page URL and one still image. THERE IS NO VIDEO FORMAT ON THIS PLATFORM — a video URL is refused outright, so never offer one. Created paused; creating it active inside a live ad group starts REAL AD SPEND, so that needs confirm:true. OpenAI REVIEWS every ad (usually a few minutes) and the ad is read back with its review status: until that says approved the ad CANNOT show, so report the review status rather than calling it live. The landing page is also checked against robots.txt for OAI-AdsBot / OAI-SearchBot blocks — a page that blocks those agents cannot run ChatGPT ads at all, and the note says so. It is categorised as a Write tool in the Hermoso MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_openai_ads_ad? +

What risk level is create_openai_ads_ad? +

How do I block create_openai_ads_ad completely? +
