set_sequence_framerate · Unreal MCP: Risk & Policy

WHAT IT DOES

What set_sequence_framerate does on Unreal

AI agents use set_sequence_framerate 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_sequence_framerate needs a policy

This tool modifies the frame rate parameter of an existing sequence, which is a reversible configuration change. It does not execute arbitrary code, delete data, or trigger financial transactions.

From the tool's definition 'Set the display frame rate of a sequence' modifies the frame rate property of a sequence object without deleting or creating the sequence itself.

Verdict

set_sequence_framerate Rate-limited

set_sequence_framerate 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Unreal, so you can run agents against it safely.

FAQ

Questions about set_sequence_framerate

What does the set_sequence_framerate tool do? +

Set the display frame rate of a sequence. 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_sequence_framerate? +

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

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

Can I rate-limit set_sequence_framerate? +

Yes. Add a rate_limit block to the set_sequence_framerate 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_sequence_framerate completely? +

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

set_sequence_framerate 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.
