set_target_temperature · Zont MCP: Risk & Policy

WHAT IT DOES

What set_target_temperature does on Zont

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

WHY IT NEEDS A POLICY

Why set_target_temperature needs a policy

The tool name strongly suggests it changes a target temperature value in the ZONT heating system, which is a write operation. While the description is empty (lowering confidence), the name and server context (heating control system) indicate this modifies device state. Misuse could affect physical comfort or safety (e.g., setting dangerously high or low temperatures), warranting high severity.

From the tool's definition Tool name 'set_target_temperature' implies modifying a temperature setpoint in a heating system.
