What list_apple_ads_keywords does on Hermoso
AI agents call list_apple_ads_keywords to retrieve information from Hermoso without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_apple_ads_keywords is rated Low
Even though list_apple_ads_keywords only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

The rule that runs list_apple_ads_keywords 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 list_apple_ads_keywords, this is the rule to start with:
list_apple_ads_keywords is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

Questions about list_apple_ads_keywords
Targeting or negative keywords with their match type, status and bid. THE TWO RESOURCES SCOPE DIFFERENTLY and Apple enforces it: TARGETING keywords (the default) need campaignId OR adGroupId — campaignId alone now returns every targeting keyword in the campaign, which Apple’s older API had no way to ask for. NEGATIVE keywords (negative:true) always need one of the two as well, and Apple splits them by LEVEL: campaignId alone returns the CAMPAIGN-level negatives that suppress the whole campaign (scope ‘campaign’, the default), scope ‘adgroup’ returns every AD-GROUP-level negative across that campaign in one call, and naming an adGroupId returns just that ad group’s. The reply states which level it counted, because the row shapes are identical and the number means different things. There is no account-wide keyword list. Apple allows up to 5000 keywords per ad group. Read-only, free. It is categorised as a Read tool in the Hermoso MCP Server, which means it retrieves data without modifying state.
Register the Hermoso MCP server in PolicyLayer and add a rule for list_apple_ads_keywords: 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.
