# set_component_property

Set component property values for UI components or custom script components. Supports setting properties of built-in UI components (e.g., cc.Label, cc.Sprite) and custom script components. Note: For node basic properties (name, active, layer, etc.), use set_node_property. For node transform properties (position, rotation, scale, etc.), use set_node_transform.

## Facts

- Tool: `set_component_property`
- Server: Cocos (`caravanglory/cocos-mcp-server`) — https://policylayer.com/tools/caravanglory-cocos-mcp-server.md
- Homepage: https://github.com/caravanglory/cocos-mcp-server
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why set_component_property is rated Medium

The tool modifies component properties in the Cocos Creator editor, which is a write operation that changes the state of game objects and UI elements. While reversible (can be undone via the undo system present in this server), the blast radius is high because a malicious agent could corrupt game logic, UI appearance, or script component behavior by setting arbitrary property values.

From the tool's own definition: "Tool description states it 'Set component property values' and 'supports setting properties of built-in UI components (e.g., cc.Label, cc.Sprite) and custom script components.' This is a modification operation that changes component state reversibly."

## Use case

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

## Recommended policy (PolicyLayer)

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

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