get_file_info

THE RISK

Low Risk

Why get_file_info needs a policy

This tool queries file/directory metadata and statistics without creating, modifying, deleting, or executing anything. It has no side effects beyond reading filesystem metadata. Severity is low because even if an AI agent misuses it, the blast radius is limited to information disclosure about file system structure, which poses minimal direct risk.

From the tool's definition Tool name is 'get_file_info' and description states it 'Extract[s] comprehensive metadata and statistics for files or directories'—purely informational retrieval with no modification capability.

POLICY

How to control get_file_info

PolicyLayer is an MCP gateway — it sits between your AI agents and Vulcan File Ops, and nothing reaches the server without passing your rules. This is the rule we recommend for get_file_info:

policy.json

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

get_file_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Vulcan File Ops — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
