POLICY

How to control get-audio-info

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 get-audio-info:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get-audio-info": {}
  }
}

get-audio-info 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.
