WHAT IT DOES

What get_actor_properties does on Unreal-MCP

AI agents call get_actor_properties 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 get_actor_properties is rated Low

The tool retrieves properties of an actor in Unreal Engine 5, which is a read operation with no side effects. Even in the context of an editor control interface, querying actor properties does not create, modify, delete, or execute operations. Confidence is slightly reduced due to empty description, but the naming convention and context provide strong evidence for Read classification.

From the tool's definition Tool name 'get_actor_properties' indicates retrieval of actor properties from Unreal Engine. The 'get_' prefix conventionally denotes read-only operations.

RECOMMENDED RULE

The rule that runs get_actor_properties 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 get_actor_properties, this is the rule to start with:

get_actor_properties Allowed

get_actor_properties is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

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 get_actor_properties call is checked against it from then on.
