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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "rename_layer",
    "arguments": {
      "newName": "<newName>",
      "compName": "<compName>",
      "layerName": "<layerName>"
    }
  }
}
```

## Why rename_layer is rated Medium

Renaming a layer is a write operation that modifies project state reversibly. The change can be easily undone (Aseprite supports undo per edit as noted in the server description). It does not execute code, delete data irreversibly, or affect financial systems. Confidence is high because the intent is explicit and unambiguous.

From the tool's own definition: "Tool name 'rename_layer' and description 'Rename a layer.' indicate a reversible metadata modification of a layer name within an Aseprite project."

## Use case

AI agents use rename_layer 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)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Ae:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "rename_layer": {
      "limits": [
        {
          "counter": "rename_layer_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
