What seq_actor_to_spline does on Uefn
AI agents use seq_actor_to_spline to create or update resources in Uefn, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Uefn environment.
Why seq_actor_to_spline is rated Medium
This tool creates or modifies a sequencer track by converting an actor's movement path into a spline-based track. This is a Write operation as it creates new data (a sequencer track) within the UEFN editor. While the conversion could overwrite existing data, it is generally reversible in an editor context. Severity is medium as misuse could corrupt animation/sequencer data in the project.

Attacks that exploit this kind of access
The rule that runs seq_actor_to_spline safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Uefn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For seq_actor_to_spline, this is the rule to start with:
seq_actor_to_spline 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 Uefn, apply this rule, and every seq_actor_to_spline call is checked against it from then on.
Questions about seq_actor_to_spline
Convert an actor's movement path to a spline-based sequencer track. It is categorised as a Write tool in the Uefn MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Uefn MCP server in PolicyLayer and add a rule for seq_actor_to_spline: 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 Uefn. Nothing to install.
seq_actor_to_spline 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 seq_actor_to_spline 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 seq_actor_to_spline. 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.
seq_actor_to_spline is provided by the Uefn MCP server (quangdang46/uefn-verse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
