WHAT IT DOES

What deep_search does on Ha Nexus Agent

AI agents call deep_search to retrieve information from Ha Nexus Agent without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why deep_search is rated Low

This tool retrieves and queries data across Home Assistant's entity/device/area/automation catalog. It performs no creation, modification, deletion, or execution of commands. The `kind` tagging mechanism is a filtering/organization feature for search results, not an action that changes state. Therefore, it is classified as Read with low severity and high confidence.

From the tool's definition Tool description states 'Search across entities, devices, areas, and automations' — a query/search operation with no modification capability indicated.

RECOMMENDED RULE

The rule that runs deep_search 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 deep_search, this is the rule to start with:

deep_search Allowed

deep_search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "deep_search": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Ha Nexus Agent, apply this rule, and every deep_search call is checked against it from then on.
