What disable_automation does on Ha Nexus Agent
AI agents use disable_automation to create or update resources in Ha Nexus Agent, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ha Nexus Agent environment.
Why disable_automation is rated Medium
Disabling an automation modifies the state of a smart home automation rule, preventing it from triggering. This is a reversible write operation (the automation can be re-enabled), not a destructive deletion. Severity is medium because disabling critical automations (e.g., security, safety systems) could have real-world consequences.
From the tool's definition 'Disable an automation' — turns off an automation, which is a reversible state change (it can be re-enabled)
Attacks that exploit this kind of access
The rule that runs disable_automation safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ha Nexus Agent, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For disable_automation, this is the rule to start with:
disable_automation 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Ha Nexus Agent, apply this rule, and every disable_automation call is checked against it from then on.
