WHAT IT DOES

What import_blueprint does on Ha Nexus Agent

AI agents use import_blueprint 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.

RISK

Why import_blueprint is rated Medium

This tool fetches content from an external URL and writes it to the Home Assistant configuration directory. It creates new files on the filesystem, which is a Write operation. The severity is medium because it introduces external content into the config system, which could be misused to install malicious blueprints, but it doesn't directly execute code or delete data.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

import_blueprint Rate-limited

import_blueprint 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 import_blueprint call is checked against it from then on.
