WHAT IT DOES

What search_parent_classes does on Unreal-MCP

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

RISK

Why search_parent_classes is rated Low

This tool retrieves or queries class inheritance information from the Unreal Engine editor—a read-only operation with no side effects. No data is created, modified, executed, or deleted. The empty description reduces confidence slightly, but the clear search semantics and sibling tool patterns (add_*, add_*) confirm this is a retrieval operation.

From the tool's definition Tool name 'search_parent_classes' indicates a query/search operation for class hierarchy information in Unreal Engine. The 'search' verb and 'parent_classes' noun suggest retrieving existing data without modification.

RECOMMENDED RULE

The rule that runs search_parent_classes safely

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

search_parent_classes Allowed

search_parent_classes 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": {
    "search_parent_classes": {}
  }
}

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

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