What reload_config does on Ha Nexus Agent
AI agents invoke reload_config to trigger actions in Ha Nexus Agent. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why reload_config is rated High
Reloading configuration triggers an active operation that re-processes and applies configuration files for smart home domains. This is an Execute-category action as it runs an external operation (configuration reload) that can alter the runtime state of automations, scripts, and scenes. While not destructive or financial, misuse could disrupt active automations or cause unintended home automation behaviors.

Attacks that exploit this kind of access
The rule that runs reload_config 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 reload_config, this is the rule to start with:
reload_config stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 reload_config call is checked against it from then on.
Questions about reload_config
Reload configuration for a domain (automation, script, scene, input_boolean, etc.). It is categorised as a Execute tool in the Ha Nexus Agent MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ha Nexus Agent MCP server in PolicyLayer and add a rule for reload_config: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ha Nexus Agent. Nothing to install.
reload_config is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the reload_config rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for reload_config. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
reload_config is provided by the Ha Nexus Agent MCP server (fistacho/ha-nexus-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
