WHAT IT DOES

What mist_ack_alarm does on API-Central

AI agents use mist_ack_alarm to create or update resources in API-Central, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your API-Central environment.

RISK

Why mist_ack_alarm is rated Medium

Acknowledging an alarm is a write operation that marks an alarm as seen/acknowledged. It modifies the state of an alarm record but does not delete data or execute code. The blast radius is low since it only changes the acknowledgment status of a single alarm, which is a reversible and minor state change.

RECOMMENDED RULE

The rule that runs mist_ack_alarm safely

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

mist_ack_alarm Rate-limited

mist_ack_alarm 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.
