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

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

## Why set_static_mesh_properties is rated Medium

This tool creates or modifies engine asset configuration (blueprint component properties) in a reversible manner. It does not execute arbitrary code, delete data permanently, or trigger financial transactions. The modification is scoped to blueprint component mesh assignment and can be undone in the Unreal editor.

From the tool's own definition: "Tool modifies blueprint component properties: 'Set the static mesh on a StaticMeshComponent in a Blueprint' — directly altering mesh assignment within a game asset."

## Use case

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

## Recommended policy (PolicyLayer)

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