What find_actors does on Unreal-MCP
AI agents call find_actors 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.
Why find_actors is rated Low
The 'find' verb is characteristic of Read operations that search or list data. In Unreal Engine context, 'find_actors' would query the scene for actor objects and return results—a retrieval operation with no side effects. Confidence is slightly reduced due to empty description, but the semantic meaning of the name is clear and consistent with Read-category tools.
From the tool's definition Tool name 'find_actors' indicates a search/query operation. The description is empty, but the naming convention and context within Unreal Engine (where actors are game objects) strongly suggest this retrieves or queries actor data without modifying state.
Attacks that exploit this kind of access
The rule that runs find_actors 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 find_actors, this is the rule to start with:
find_actors is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Unreal-MCP, apply this rule, and every find_actors call is checked against it from then on.
Questions about find_actors
find_actors is a read tool on the Unreal MCP server. It is categorised as a Read tool in the Unreal-MCP MCP Server, which means it retrieves data without modifying state.
Register the Unreal MCP server in PolicyLayer and add a rule for find_actors: 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-MCP. Nothing to install.
find_actors 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_actors 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_actors. 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_actors is provided by the Unreal MCP server (aadeshrao123/unreal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
