RECOMMENDED RULE

The rule that runs create_analytics_key_event 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_analytics_key_event, this is the rule to start with:

create_analytics_key_event Rate-limited

create_analytics_key_event 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.

  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Hermoso, apply this rule, and every create_analytics_key_event call is checked against it from then on.

FAQ

Questions about create_analytics_key_event

What does the create_analytics_key_event tool do? +

Mark an event GA4 ALREADY COLLECTS as a KEY EVENT — what GA4 calls a conversion since the 2024 rename (the resource is keyEvents; the old conversionEvents spelling is deprecated). This is what makes an event countable as a result in reports and importable into Google Ads as a conversion. THE EVENT NAME MUST MATCH AN EVENT THE SITE ALREADY SENDS (. 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_analytics_key_event? +

Register the Hermoso MCP server in PolicyLayer and add a rule for create_analytics_key_event: 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_analytics_key_event? +

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

Can I rate-limit create_analytics_key_event? +

Yes. Add a rate_limit block to the create_analytics_key_event 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_analytics_key_event completely? +

Set action: deny in the PolicyLayer policy for create_analytics_key_event. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create_analytics_key_event? +
