WHAT IT DOES

What list_script_traces does on Ha Nexus Agent

AI agents call list_script_traces 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 list_script_traces is rated Low

This tool retrieves and queries historical execution data (trace summaries) for scripts without modifying, deleting, or executing anything. It is a passive read operation that returns audit/log information about past script runs. No state changes, no code execution, no data destruction. Appropriate for the Read category with low severity.

From the tool's definition Tool name is 'list_script_traces' and description states 'List trace summaries (recent runs) for a script' — clearly a retrieval operation with no side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

list_script_traces Allowed

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

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

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 list_script_traces call is checked against it from then on.
