THE RISK

Why test-animation needs a policy

The tool executes animation functionality inside After Effects, which constitutes running/triggering external operations in a creative application. The description is vague, lowering confidence, but 'test animation functionality' implies executing or rendering animation actions rather than merely reading data or writing static properties.

From the tool's definition 'Test animation functionality in After Effects' — triggers animation operations within After Effects

Documented attack patterns abuse exactly the kind of access test-animation gives an agent:

POLICY

How to control test-animation

PolicyLayer is an MCP gateway — it sits between your AI agents and After Effects MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for test-animation:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "test-animation": {
      "limits": [
        {
          "counter": "test-animation_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

test-animation stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register After Effects MCP Server — 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 test-animation

What does the test-animation tool do? +

Test animation functionality in After Effects. It is categorised as a Execute tool in the After Effects MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on test-animation? +

Register the After Effects MCP Server MCP server in PolicyLayer and add a rule for test-animation: 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 After Effects MCP Server. Nothing to install.

What risk level is test-animation? +

test-animation is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit test-animation? +

Yes. Add a rate_limit block to the test-animation 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 test-animation completely? +

Set action: deny in the PolicyLayer policy for test-animation. 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 test-animation? +

test-animation is provided by the After Effects MCP Server MCP server (thellamainator/after-effects-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every After Effects MCP Server tool call.

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