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

```json
{
  "jsonrpc": "2.0",

## Why unity_terrain_import_heightmap is rated Medium

This tool creates or modifies terrain geometry by importing heightmap data, which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, or move money. While it affects game assets, the operation can be undone through normal version control or re-importing.

From the tool's own definition: "Tool name includes 'import' and description states 'Import a heightmap from a RAW file or texture asset into the terrain' — this modifies terrain data by ingesting external heightmap sources."

## Use case

AI agents use unity_terrain_import_heightmap 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)
