WHAT IT DOES

What list_dir does on Mcp Control Plane

AI agents call list_dir to retrieve information from Mcp Control Plane 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_dir is rated Low

This tool only queries and returns file metadata from a remote directory without creating, modifying, deleting, or executing any operations. It is a pure read operation with minimal risk—the primary concern would be exposure of sensitive file paths or metadata, but this depends on access controls rather than the tool's inherent capability.

From the tool's definition Tool name 'list_dir' and description 'List a remote directory with file metadata' indicate retrieval of directory contents with no modification or execution capability.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_dir safely

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

list_dir Allowed

list_dir 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_dir": {}
  }
}

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

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