WHAT IT DOES

What list_config_categories does on Commodore 64 Ultimate Computer MCP Server

AI agents call list_config_categories 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.

POLICY

How to control list_config_categories

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 list_config_categories:

policy.json

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

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