## Facts

- Tool: `light_bulk_adjust`
- Server: Uefn (`quangdang46/uefn-verse-mcp`) — https://policylayer.com/tools/quangdang46-uefn-verse-mcp.md
- Homepage: https://github.com/quangdang46/uefn-verse-mcp
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified

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

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

## Why light_bulk_adjust is rated Medium

Based on the name alone, this tool likely adjusts properties (brightness, color, intensity) of multiple lights in bulk within the UEFN editor. 'Adjust' implies modification of existing data, which maps to Write. Bulk operations increase blast radius slightly. Confidence is reduced due to empty description.

From the tool's own definition: "Tool name 'light_bulk_adjust' — no description provided."

## Use case

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

## Recommended policy (PolicyLayer)

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

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