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

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

## Why unity_terrain_resize is rated Medium

Resizing terrain modifies scene geometry and asset properties, which classifies it as a Write action (creates or modifies data reversibly). It is not Read (no side effects), Execute (doesn't run arbitrary code), Destructive (the operation is reversible and doesn't permanently delete data), Financial (no money involved), or Other.

From the tool's own definition: "Tool name 'unity_terrain_resize' and description 'Resize an existing terrain' indicate modification of terrain data in a Unity scene. This is a reversible write operation that alters existing game assets."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
