export_sequence_fbx · Unreal MCP: Risk & Policy

WHAT IT DOES

What export_sequence_fbx does on Unreal

AI agents use export_sequence_fbx 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 export_sequence_fbx needs a policy

This tool writes/creates a new FBX file from an existing level sequence. While it produces output, the action is reversible (the exported file can be deleted or re-exported), making it Write rather than Destructive.

From the tool's definition The tool exports (outputs/writes) a level sequence to FBX format. 'Export' involves creating and writing a new file artifact, which is a reversible data creation action.

export_sequence_fbx Rate-limited

export_sequence_fbx 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 export_sequence_fbx

What does the export_sequence_fbx tool do? +

Export a level sequence to FBX. 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 export_sequence_fbx? +

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

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

Can I rate-limit export_sequence_fbx? +

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

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

export_sequence_fbx 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.
