RECOMMENDED RULE

The rule that runs create_pinterest_ads_ad_group safely

create_pinterest_ads_ad_group Rate-limited

create_pinterest_ads_ad_group 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_pinterest_ads_ad_group

What does the create_pinterest_ads_ad_group tool do? +

Add an ad group to an existing Pinterest campaign — optionally with its ad in the same call. Created PAUSED by default. Pinterest REQUIRES every ad group to target at least one place, so targetingSpec must carry a GEO array or a LOCATION object. If the parent campaign is already LIVE (ACTIVE), creating this ad group ACTIVE starts REAL AD SPEND on the next auction, exactly like activating it — show the user what would begin serving, get an explicit yes, then pass confirm:true. Leaving it paused never needs confirmation. Read back from Pinterest before you are told it exists. 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_pinterest_ads_ad_group? +

Register the Hermoso MCP server in PolicyLayer and add a rule for create_pinterest_ads_ad_group: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Hermoso. Nothing to install.

What risk level is create_pinterest_ads_ad_group? +

Yes. Add a rate_limit block to the create_pinterest_ads_ad_group rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create_pinterest_ads_ad_group completely? +
