WHAT IT DOES

What acknowledge_alarm does on AIRIOT MCP Server

AI agents use acknowledge_alarm to create or update resources in AIRIOT MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AIRIOT MCP Server environment.

WHY IT NEEDS A POLICY

Why acknowledge_alarm needs a policy

This tool modifies the state of an alarm record from 'active' to 'acknowledged'. It is a reversible state change/update operation, making it a Write action. It does not delete data, execute code, or involve financial transactions. Severity is medium because misuse could mask active alarms in an IoT platform, potentially hiding real incidents. Confidence slightly reduced because the tool is marked deprecated ([已废弃]).

From the tool's definition 确认告警，将告警状态从active改为acknowledged (changes alarm status from active to acknowledged)

acknowledge_alarm Rate-limited

acknowledge_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.
