Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Umodel-MCP

License: MIT GitHub

English | 简体中文

面向 umodel 的 MCP 服务器, 让任意 MCP 客户端通过自然语言完成 Unreal Engine 游戏资源的列表、解包、导出操作

特性

  • 纯解包零依赖:pak_list / pak_extract 为纯 TypeScript 实现,直接解析 .pak 索引并提取原始 .uasset/.uexp 文件,无需下载 umodel
  • 支持加密 pak:AES-256 索引/条目加密,含标准模式与 bitflip 变体; 密钥仅存会话内存
  • 完整导出链路:网格、贴图、动画、声音导出为 gltf、psk、png、dds 等格式 (依赖 umodel 可执行文件)

环境要求

  • Node.js 18 或更高版本
  • 任意支持 MCP 的客户端(Hermes 、Claude Code、Cursor、PI、Codex 等)
  • 仅导出转换功能需要:umodel

安装

标准配置

{
  "mcpServers": {
    "umodel": {
      "command": "npx",
      "args": ["-y", "umodel-mcp"]
    }
  }
}

也可以直接把这句话发给你的 agent:"帮我安装并注册 umodel-mcp,重载 MCP 连接后验证可用"

claude mcp add umodel npx -- -y umodel-mcp
codex mcp add umodel npx "-y" "umodel-mcp"
git clone [email protected]:CHA1007/Umodel-MCP.git
cd Umodel-MCP
npm install
npm run build

然后在 MCP 客户端配置中注册:

{
  "mcpServers": {
    "umodel": {
      "command": "node",
      "args": ["<本仓库绝对路径>/dist/index.js"]
    }
  }
}
