## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "ae_apply_effect",
    "arguments": {}

## Why ae_apply_effect is rated Medium

The tool modifies existing layers by applying effects, which is a reversible write operation typical of creative software. While it changes project state, the effects can be removed or adjusted. This is less severe than Execute (which would run arbitrary code) or Destructive (which would permanently delete), making it Write category.

From the tool's own definition: "Tool applies visual effects to layers, which modifies the composition's visual properties. The description uses 'Apply' and context includes sibling tools like ae_add_keyframe, ae_animate_property, and ae_apply_effect_preset, all of which are reversible…"

## Use case

AI agents use ae_apply_effect 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.

## Recommended policy (PolicyLayer)
