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 🙏

mcp-file-adapter

v0.2.0

Published

Local MCP stdio adapter for remote file service.

Readme

mcp-file-adapter

本地 MCP stdio 适配器:将 4 个工具调用转为远程 HTTP 请求,并直接上传/下载文件。

变更记录见 CHANGELOG.md

最新变更(npm 页面可见)

  • 0.2.0:工具改为结构化入参(biz/req/scope/rel_path),移除旧 path/remote_path 透传。
  • 0.1.9:鉴权 token 改为启动参数 --auth-token
  • 0.1.8:README 增加内联版本摘要,npm 页面可直接查看最近变更。
  • 0.1.7:发布包包含 README.mdCHANGELOG.md

环境变量

  • REMOTE_BASE_URL: 远程服务地址,默认 http://localhost:8080
  • TIMEOUT_MS: 请求超时(毫秒),默认 30000
  • REMOTE_USER: 用户标识(当未传 --user 时生效)

启动参数

  • --remote-base-url=...: 覆盖 REMOTE_BASE_URL
  • --auth-token=...: 远程服务鉴权 token(必填)
  • --user=...: 用户标识,优先级高于 REMOTE_USER

参数解析使用 node:util.parseArgs(严格模式),未知参数会直接报错退出。

鉴权

  • Header: Authorization: Bearer <auth-token>

路径映射规则

  • 工具不再接受完整 remote_path,统一使用结构化字段:bizreqscoperel_path
  • scope=shared -> archive/<biz>/<req>/shared/<rel_path>
  • scope=user -> archive/<biz>/<req>/users/<user>/<rel_path>user 来自 --userREMOTE_USER
  • rel_path 为空时表示对应 scope 的根目录

注意:当前是“约定隔离”,不是“安全隔离”。持有 token 的请求仍可访问任意路径。

工具

  • list_files { biz, req, scope, rel_path? }
    • biz/req: 业务域与需求标识
    • scope: shareduser
    • rel_path: scope 下相对路径,空表示 scope 根目录
  • dir_mkdir { biz, req, scope, rel_path?, recursive? }
    • recursive: 是否递归创建父目录(默认 true)
  • upload_file { local_path, biz, req, scope, rel_path, overwrite?, mkdirs? }
    • local_path: 本地文件路径(相对路径基于当前工作目录)
    • overwrite: 是否覆盖远程同名文件
    • mkdirs: 是否创建远程父目录
  • download_file { biz, req, scope, rel_path, local_path, overwrite?, mkdirs? }
    • local_path: 本地目标路径(相对路径基于当前工作目录)
    • overwrite: 是否覆盖本地同名文件
    • mkdirs: 是否创建本地父目录

使用方式

先固定一组上下文字段:

  • biz: 业务域,例如 kilimallspec
  • req: 需求 ID,例如 234898756
  • scope: shareduser

1) 列共享目录

{
  "tool": "list_files",
  "arguments": {
    "biz": "kilimallspec",
    "req": "234898756",
    "scope": "shared",
    "rel_path": ""
  }
}

2) 在用户目录创建子目录

{
  "tool": "dir_mkdir",
  "arguments": {
    "biz": "kilimallspec",
    "req": "234898756",
    "scope": "user",
    "rel_path": "design",
    "recursive": true
  }
}

3) 上传文件到共享目录

{
  "tool": "upload_file",
  "arguments": {
    "local_path": "kilimallspec/design/234898756/234898756-物品同步-design.md",
    "biz": "kilimallspec",
    "req": "234898756",
    "scope": "shared",
    "rel_path": "234898756-物品同步-design.md",
    "overwrite": true,
    "mkdirs": true
  }
}

4) 下载共享 PRD 到本地

{
  "tool": "download_file",
  "arguments": {
    "biz": "kilimallspec",
    "req": "234898756",
    "scope": "shared",
    "rel_path": "234898756-物品同步-prd.md",
    "local_path": "kilimallspec/design/234898756/234898756-物品同步-prd.md",
    "overwrite": true,
    "mkdirs": true
  }
}

5) 迁移提示(从旧参数到新参数)

  • 旧:list_files(path) -> 新:list_files(biz, req, scope, rel_path)
  • 旧:upload_file(remote_path) -> 新:upload_file(biz, req, scope, rel_path)
  • 旧:download_file(remote_path) -> 新:download_file(biz, req, scope, rel_path)

运行

npm install
npm run dev -- --auth-token=your-token

测试

npm test

发布

npm run build
npm publish
