+# Unreal Engine
+
+[中文](README_CN.md)
+
+A non-UI ZCode plugin connecting to a separately installed Unreal Editor through Epic's experimental Unreal MCP. Includes the official `unreal-mcp`, `create-toolset`, and `unreal-skill` skills, adapted for ZCode. No engine binaries, native proxy, or UI panel are bundled.
+
+## Setup
+
+1. Install a UE build that includes `ModelContextProtocol` and `AllToolsets` (documented for UE 5.8), then enable both in the intended project.
+2. Open the project in Unreal Editor and run `ModelContextProtocol.StartServer` in the editor console.
+3. Install and enable **Unreal Engine** in the ZCode plugin marketplace. The `endpoint` plugin setting defaults to `http://127.0.0.1:8000/mcp`; change it if your editor uses a different port. Do not add a duplicate project MCP connection.
+4. Ask ZCode: “Use Unreal MCP to identify the connected project and list the scene actors without changing anything.” A successful read-only tool call verifies live access; a configured endpoint alone does not.
+
+Use `unreal-mcp` for editor operations, `create-toolset` to expose new UE tools, and `unreal-skill` for UE project Agent Skills. See [setup](skills/unreal-mcp/references/setup.md) and [troubleshooting](skills/unreal-mcp/references/operations.md).
+
+## Connection and safety
+
+The endpoint is resolved on the machine running the ZCode agent. In SSH/WSL/Docker workspaces, loopback points to that environment, not your desktop. UE MCP has no authentication by default: keep it on loopback or use an explicitly protected connection. Verify the project identity before edits when several editors are running. Save before bulk changes; not all MCP changes are undoable. The editor must be running and tool availability depends on enabled UE toolsets.
+
+## Provenance
+
+Skills originate from [EpicGames/unreal-engine-skills-for-claude-code-plugin](https://github.com/EpicGames/unreal-engine-skills-for-claude-code-plugin), pinned in [upstream.json](skills/upstream.json). MIT notices are retained in each skill directory. ZCode adapts connection/setup guidance; this package is maintained by Z.ai and does not imply Epic endorsement. Unreal Engine licensing remains separate. The marketplace icon is served from the plugin assets CDN.

+# Unreal Engine
+
+[English](README.md)
+
+非 UI 的 ZCode 插件，通过 Epic 实验性 Unreal MCP 连接独立安装的 Unreal Editor。包含适配 ZCode 的官方 `unreal-mcp`、`create-toolset`、`unreal-skill` 三个 Skills，不打包引擎、原生代理或 UI 面板。
+
+## 配置
+
+1. 安装包含 `ModelContextProtocol` 和 `AllToolsets` 的 UE 版本（官方文档对应 UE 5.8），在目标项目中启用两者。
+2. 用 Unreal Editor 打开项目，在编辑器控制台运行 `ModelContextProtocol.StartServer`。
+3. 在 ZCode 插件市场安装并启用 **Unreal Engine**。插件设置 `endpoint` 默认 `http://127.0.0.1:8000/mcp`，端口不同时修改此设置；不要重复添加项目级 MCP 连接。
+4. 对 ZCode 说：“使用 Unreal MCP 确认连接的项目，列出场景中的对象，不做修改。”成功的只读调用才证明已连通；仅配置好地址不代表编辑器可用。
+
+`unreal-mcp` 用于操作编辑器，`create-toolset` 用于扩展 UE 工具，`unreal-skill` 用于编写 UE 项目 Agent Skills。详见[配置](skills/unreal-mcp/references/setup.md)与[排障](skills/unreal-mcp/references/operations.md)。
+
+## 连接与安全
+
+地址由运行 ZCode Agent 的机器解析。SSH、WSL、Docker 工作区里的回环地址指向对应环境，不是桌面。UE MCP 默认无鉴权，应保持回环监听，跨机器时显式使用受保护连接。多个编辑器同时运行时，先确认项目身份再修改。批量修改前保存，不是所有 MCP 操作都支持撤销。编辑器必须运行，可用工具取决于启用的 UE 工具集。
+
+## 来源
+
+Skills 来自 [EpicGames/unreal-engine-skills-for-claude-code-plugin](https://github.com/EpicGames/unreal-engine-skills-for-claude-code-plugin)，版本固定在 [upstream.json](skills/upstream.json)，各 Skill 目录保留 MIT 许可。ZCode 适配连接和配置说明；本插件由 Z.ai 维护，不表示 Epic 背书。Unreal Engine 本身遵循独立授权。市场图标由插件资源 CDN 提供。
