WHAT IT DOES

What container_files_list does on Cloudflare

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

RISK

Why container_files_list is rated Low

The tool performs a directory listing operation which retrieves information about files without any side effects. It is a pure read operation analogous to 'ls' or 'dir'. The low severity reflects that unauthorized directory enumeration alone is unlikely to cause significant harm, though it may reveal system structure information that could inform further attacks.

From the tool's definition Tool description explicitly states 'This just reads the contents of the current working directory' with no modification or execution capability.

RECOMMENDED RULE

The rule that runs container_files_list safely

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

container_files_list Allowed

container_files_list 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": {
    "container_files_list": {}
  }
}

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

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