Show the inheritance tree for a class in the project.
AI agents call get_project_class_hierarchy to retrieve information from Unreal Project without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and displays class inheritance relationships from the Unreal Engine project index. It has no side effects, does not modify data, execute code, delete anything, or commit financial actions. It is a pure information retrieval operation consistent with other sibling tools like get_config_values and get_plugin_info.
From the tool's definition Tool name and description indicate retrieval of structural information: 'Show the inheritance tree for a class' is a query operation that returns existing class hierarchy data from the indexed project database without modification.
Attacks that exploit this kind of access
Show the inheritance tree for a class in the project. It is categorised as a Read tool in the Unreal Project MCP Server, which means it retrieves data without modifying state.
Register the Unreal Project MCP server in PolicyLayer and add a rule for get_project_class_hierarchy: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Unreal Project. Nothing to install.
get_project_class_hierarchy is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_project_class_hierarchy rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_project_class_hierarchy. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_project_class_hierarchy is provided by the Unreal Project MCP server (tumourlove/deprecated-unreal-project-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
