Why seq_batch_keyframe needs a policy

The name suggests batch keyframe operations in a sequencer (likely animation/cinematic sequencer in UEFN), which could be a Write operation (creating/modifying keyframes). However, with no description, the exact behavior is unclear. Based on sibling tools context (UEFN editor manipulation), this likely writes keyframe data to a sequencer timeline, which would be Write category.

From the tool's definition Tool name is 'seq_batch_keyframe' but description is empty/uninformative.

POLICY

How to control seq_batch_keyframe

PolicyLayer is an MCP gateway — it sits between your AI agents and Uefn, and nothing reaches the server without passing your rules. This is the rule we recommend for seq_batch_keyframe:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "seq_batch_keyframe": {
      "limits": [
        {
          "counter": "seq_batch_keyframe_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

seq_batch_keyframe gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register Uefn — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about seq_batch_keyframe

What does the seq_batch_keyframe tool do? +

seq_batch_keyframe. It is categorised as a Other tool in the Uefn MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on seq_batch_keyframe? +

Register the Uefn MCP server in PolicyLayer and add a rule for seq_batch_keyframe: 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.

What risk level is seq_batch_keyframe? +

seq_batch_keyframe is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit seq_batch_keyframe? +

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

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

seq_batch_keyframe 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.

Enforce policy on every Uefn tool call.

Start from Uefn, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
