Why list-layer-effects needs a policy

This tool retrieves metadata about effects applied to a layer in After Effects. It performs no side effects, creates no new data, executes no code, and cannot cause irreversible changes. The 'list' verb and the retrieval-focused description clearly position this as a Read operation with minimal risk.

From the tool's definition Tool name 'list-layer-effects' and description 'List effects on a layer, with optional recursive property details' indicate a query operation that retrieves and displays information without modifying or executing anything.

POLICY

How to control list-layer-effects

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 list-layer-effects:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list-layer-effects": {}
  }
}

list-layer-effects is read-only, so it stays allowed — but 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.
