resolve_alarm · AIRIOT MCP Server MCP: Risk & Policy

WHAT IT DOES

What resolve_alarm does on AIRIOT MCP Server

AI agents use resolve_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 resolve_alarm needs a policy

This tool modifies existing alarm data by changing their status from active to resolved. This is a reversible operation (alarms can be updated back to other states), fitting the Write category rather than Destructive. Severity is medium because misuse could suppress critical safety alerts in an IoT platform, affecting operational visibility and potentially masking system issues, but the change is not irreversible.

From the tool's definition Tool description states it modifies alarm status to 'resolved' (解除告警，将告警状态改为resolved). The Chinese annotation indicates this is deprecated in favor of update_warning, but the function itself performs a state change operation on alarm records.

Verdict

resolve_alarm Rate-limited

resolve_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.
