# Show HN: ClaudeFS – Give claude.ai access to a local folder, no local process

Connect a local folder to [claude.ai](https://claude.ai). A browser extension (MV3) for Chrome and Edge: authorize a folder once, and Claude can read, search, and edit the files in it right from the chat — no desktop app, no API key, no command line. Works on the free claude.ai plan.

**Prerequisites:** a Chromium-based browser (Chrome, Edge, etc.) with Manifest V3 and File System Access API support, plus a [claude.ai](https://claude.ai) account.

**Edge (recommended):** install from the[Microsoft Edge Add-ons store](https://microsoftedge.microsoft.com/addons/detail/claudefs/mfngoeppdmboplcgllagnnggehdcigna).**Chrome / from source:** clone or download this repository (no build step needed), then load the`src/`

folder via Developer mode → "Load unpacked".*(A Chrome Web Store listing is under review — this section will be updated once it's live.)*

- Open
[claude.ai](https://claude.ai). - Click the connect button at the bottom right of the page and pick a local folder.
- Ask Claude something like "read xx file" — that's it.

Tip: the file tools only appear in Claude's available tool list after it discovers them — if Claude doesn't use the tools at first, rephrase and mention file operations explicitly.

All file operations run locally in your browser; the extension itself sends nothing to any server. File content that Claude reads via the tools goes only into your claude.ai conversation — the same as if you had pasted or uploaded it there yourself. Your folder reference is stored only in the browser's local storage (IndexedDB). Full policy: [PRIVACY.md](/vincentping/claudeFS/blob/main/PRIVACY.md).

Every write operation (write / edit / move / delete, etc.) shows a diff confirmation dialog before touching your disk — you review the change and decide whether to approve it.

一个支持 Chrome 与 Edge 的浏览器扩展（MV3），让你在 [claude.ai](https://claude.ai) 授权一个本地文件夹后，Claude 能像 agent 一样直接读写该文件夹里的文件——零安装、无 API Key、无命令行，claude.ai 免费版即可使用。

**前置条件：**一个支持 Manifest V3 与 File System Access API 的 Chromium 内核浏览器（Chrome、Edge 等），以及一个 [claude.ai](https://claude.ai) 账号。

- **Edge（推荐）：**从
[Microsoft Edge 扩展商店](https://microsoftedge.microsoft.com/addons/detail/claudefs/mfngoeppdmboplcgllagnnggehdcigna)直接安装。 - **Chrome / 源码安装：**克隆或下载本仓库（无需构建），在开发者模式下"加载已解压的扩展程序"，选择
`src/`

文件夹。*（Chrome 应用商店版本正在审核中，上架后会更新此处。）*

- 打开
[claude.ai](https://claude.ai)。 - 点击页面右下角的连接按钮，选择要授权的本地文件夹。
- 对 Claude 说"读一下 xx 文件"之类的话即可。

提示：文件工具需要 Claude 先检索到，才会出现在它当次对话可用的工具列表里——如果它一开始没用工具，换个更明确提到文件操作的说法再试一次。

所有文件操作都在你本地浏览器完成，扩展自身不向任何服务器传输任何数据；Claude 通过工具读到的文件内容，只会进入你正在使用的 claude.ai 对话（等同于你手动粘贴/上传给 Claude）。你选的文件夹引用仅保存在浏览器本地存储（IndexedDB）中。完整政策见 [PRIVACY.md](/vincentping/claudeFS/blob/main/PRIVACY.md)。

所有写操作（write / edit / move / delete 等）执行前都会弹出 diff 确认，你可以查看改动内容后再决定是否放行。
