set_skeletal_mesh_lod · Unreal MCP: Risk & Policy

WHAT IT DOES

What set_skeletal_mesh_lod does on Unreal

AI agents use set_skeletal_mesh_lod to create or update resources in Unreal — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Unreal environment.

WHY IT NEEDS A POLICY

Why set_skeletal_mesh_lod needs a policy

This tool modifies LOD (Level of Detail) settings on skeletal mesh assets, which is a reversible write operation. It changes asset properties but does not delete data, execute arbitrary code, or cause destructive changes. The severity is medium because misconfiguration could impact game performance or rendering quality, but changes are reversible through reconfiguration.

From the tool's definition Tool name 'set_skeletal_mesh_lod' and description 'Configure LOD settings on a skeletal mesh' indicate modification of mesh properties. The verb 'set' and 'configure' denote state changes to existing assets.

Verdict

set_skeletal_mesh_lod Rate-limited

set_skeletal_mesh_lod stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about set_skeletal_mesh_lod

What does the set_skeletal_mesh_lod tool do? +

Configure LOD settings on a skeletal mesh. It is categorised as a Write tool in the Unreal MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_skeletal_mesh_lod? +

Register the Unreal MCP server in PolicyLayer and add a rule for set_skeletal_mesh_lod: 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. Nothing to install.

What risk level is set_skeletal_mesh_lod? +

set_skeletal_mesh_lod is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_skeletal_mesh_lod? +

Yes. Add a rate_limit block to the set_skeletal_mesh_lod 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.

How do I block set_skeletal_mesh_lod completely? +

Set action: deny in the PolicyLayer policy for set_skeletal_mesh_lod. 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.

What MCP server provides set_skeletal_mesh_lod? +

set_skeletal_mesh_lod is provided by the Unreal MCP server (sam-david/unreal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
