WHAT IT DOES

What create_folder does on Ae

AI agents use create_folder to create or update resources in Ae, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ae environment.

Parameter	Type	Required	Description
`name`	string	Yes	Folder name.
`save`	boolean	—	Save the project after creating the folder. Defaults to false.
`timeoutMs`	number	—	Process timeout in milliseconds. Defaults to 120000.
`parentName`	string	—	Optional existing parent folder name.
`projectPath`	string	—	Optional absolute path to an .aep file to open first.

Parameters from the server's own tool schema.

RISK

Why create_folder is rated Medium

An AI agent can call create_folder faster than any human can review: one bad instruction and it creates or modifies resources in Ae by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_folder safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ae, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_folder, this is the rule to start with:

create_folder Rate-limited

create_folder 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.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_folder": {
      "limits": [
        {
          "counter": "create_folder_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Ae, apply this rule, and every create_folder call is checked against it from then on.
