WHAT IT DOES

What list_workspace does on Nodebench

AI agents call list_workspace to retrieve information from Nodebench 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_workspace is rated Low

This tool queries and displays file system information (names, sizes, dates) without modifying, executing, or deleting any data. It is a straightforward directory listing utility with no side effects, fitting the Read category.

From the tool's definition Tool name 'list_workspace' and description 'List files in the agent workspace. Shows folder tree with file sizes and dates.' indicate a read-only operation that retrieves directory and file metadata.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_workspace safely

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

list_workspace Allowed

list_workspace 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": {
    "list_workspace": {}
  }
}

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

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