FAQ

Questions about create_reddit_ads_audience

What does the create_reddit_ads_audience tool do? +

Create an empty custom audience on a Reddit ad account, then fill it with update_reddit_ads_audience_users. Reddit only supports ONE kind of audience through the API — an uploaded CUSTOMER LIST matched on hashed emails and mobile advertising ids; pixel-retargeting, engagement and lookalike audiences are built by Reddit itself in Ads Manager and cannot be created here. The audience arrives empty and stays unusable until it matches roughly 1,000 redditors, and Reddit takes up to 4 hours to show a size change and up to 36 hours to finish processing a list — so do not create, upload and then report success on reach in the same breath. Free. 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_reddit_ads_audience? +

Register the Hermoso MCP server in PolicyLayer and add a rule for create_reddit_ads_audience: 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_reddit_ads_audience? +

create_reddit_ads_audience is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
