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.
| Parameter | Type | Required | Description |
|---|---|---|---|
output_path | string | Yes | Output FBX file path |
sequence_path | string | Yes | LevelSequence asset path |
Parameters from the server's own tool schema.
Why export_sequence_fbx is rated Medium
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.
Attacks that exploit this kind of access
The rule that runs export_sequence_fbx safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Unreal, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For export_sequence_fbx, this is the rule to start with:
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.
The button opens the PolicyLayer dashboard: create your workspace, connect Unreal, apply this rule, and every export_sequence_fbx call is checked against it from then on.
Questions about export_sequence_fbx
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.
export_sequence_fbx accepts 2 parameters: output_path, sequence_path. Required: output_path, sequence_path. The full parameter table on this page comes from the server's own tool schema.
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.
export_sequence_fbx is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
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.
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.
export_sequence_fbx is provided by the Unreal MCP server (@jjpxdev/unreal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
