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

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

## Why material_list_presets is rated Low

This tool retrieves and displays existing material presets without creating, modifying, deleting, or executing any operations. It is a read-only informational operation with minimal security risk. The blast radius if misused is negligible—an AI agent listing presets cannot damage assets, consume resources significantly, or alter editor state.

From the tool's own definition: "Tool name 'material_list_presets' and description 'List all saved material presets available for quick application' indicate a query/retrieval operation with no side effects."

## Use case

AI agents call material_list_presets to retrieve information from Uefn without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "material_list_presets": {}
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
