create_level_sequence · Unreal MCP: Risk & Policy

WHAT IT DOES

What create_level_sequence does on Unreal

AI agents use create_level_sequence 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 create_level_sequence needs a policy

This tool creates a new LevelSequence asset, which is a reversible write operation (the asset can be deleted or recreated). It does not delete data (ruling out Destructive), execute arbitrary code (ruling out Execute), involve financial transactions (ruling out Financial), or merely read data (ruling out Read).

From the tool's definition Tool name 'create_level_sequence' and description 'Create a new LevelSequence asset for cinematics' indicate creation of a new asset resource.

Verdict

create_level_sequence Rate-limited

create_level_sequence 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 create_level_sequence

What does the create_level_sequence tool do? +

Create a new LevelSequence asset for cinematics. 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 create_level_sequence? +

Register the Unreal MCP server in PolicyLayer and add a rule for create_level_sequence: 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 create_level_sequence? +

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

Can I rate-limit create_level_sequence? +

Yes. Add a rate_limit block to the create_level_sequence 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 create_level_sequence completely? +

Set action: deny in the PolicyLayer policy for create_level_sequence. 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 create_level_sequence? +

create_level_sequence 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.
