Search for UE macros (UCLASS, UPROPERTY, UFUNCTION, etc.) with optional filtering by type and specifiers.
AI agents call find_ue_macros to retrieve information from Ue Codegraph without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries metadata about Unreal Engine macros from a SQLite database. It performs read-only operations (search/filter) with no side effects. No code execution, data modification, or destructive actions are possible. The blast radius of misuse is minimal — worst case is disclosure of codebase structure information that is typically non-sensitive.
From the tool's definition Tool description states 'Search for UE macros' — a query/search operation with no mention of modification, deletion, or execution. The tool filters and retrieves macro information from an indexed codebase.
Attacks that exploit this kind of access
Search for UE macros (UCLASS, UPROPERTY, UFUNCTION, etc.) with optional filtering by type and specifiers. It is categorised as a Read tool in the Ue Codegraph MCP Server, which means it retrieves data without modifying state.
Register the Ue Codegraph MCP server in PolicyLayer and add a rule for find_ue_macros: 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 Ue Codegraph. Nothing to install.
find_ue_macros 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 find_ue_macros 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 find_ue_macros. 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.
find_ue_macros is provided by the Ue Codegraph MCP server (yomenstyle/ue-codegraph-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
