WHAT IT DOES

What get_file_info does on Commodore 64 Ultimate Computer MCP Server

AI agents call get_file_info to retrieve information from Commodore 64 Ultimate Computer MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why get_file_info needs a policy

This tool retrieves and queries file metadata from a Commodore 64 device without creating, modifying, deleting, or executing any operations. It is purely informational and carries minimal security risk—the worst outcome would be exposure of file metadata, which is typically low-impact information.

From the tool's definition Tool name 'get_file_info' and description 'Get metadata about a file' indicate data retrieval with no modification or side effects.

POLICY

How to control get_file_info

PolicyLayer is an MCP gateway — it sits between your AI agents and Commodore 64 Ultimate Computer MCP Server, 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.
