WHAT IT DOES

What bootenv_list does on Nasbridge

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

RISK

Why bootenv_list is rated Low

This tool queries and displays information about boot environments without creating, modifying, deleting, or executing any operations. It is a pure read operation with minimal security risk even if misused by an AI agent, as it only retrieves system state information.

From the tool's definition Tool name 'bootenv_list' and description 'List all boot environments. Shows name, active status, creation date, size, and keep flag' indicate a retrieval operation with no side effects.

RECOMMENDED RULE

The rule that runs bootenv_list safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nasbridge, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For bootenv_list, this is the rule to start with:

bootenv_list Allowed

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

  "tools": {
    "bootenv_list": {}
  }
}

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

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