The extension runs all file operations locally in the browser and requires only a claude.ai account and a Chromium-based browser with Manifest V3 and File System Access API support. ClaudeFS is an independent open-source project not affiliated with Anthropic.", "body_md": "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.\n\n**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.\n\n**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/`\n\nfolder via Developer mode → \"Load unpacked\".*(A Chrome Web Store listing is under review — this section will be updated once it's live.)*\n\n- Open\n[claude.ai](https://claude.ai). - Click the connect button at the bottom right of the page and pick a local folder.\n- Ask Claude something like \"read xx file\" — that's it.\n\nTip: 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.\n\nAll 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).\n\nEvery 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.\n\nclaudeFS is an independent open-source project, not affiliated with or endorsed by Anthropic. Claude is a trademark of Anthropic.\n\nMIT — see [LICENSE](/vincentping/claudeFS/blob/main/LICENSE).\n\n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。\n\n**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。\n\n- **Edge（推荐）：**从\n[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\n`src/`\n\n文件夹。*（Chrome 应用商店版本正在审核中，上架后会更新此处。）*\n\n- 打开\n[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。\n- 对 Claude 说\"读一下 xx 文件\"之类的话即可。\n\n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。\n\n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)。\n\n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。\n\n本项目并非 Anthropic 官方产品，与 Anthropic 无关联、未获其背书。Claude 是 Anthropic 的商标。\n\nMIT，见 [LICENSE](/vincentping/claudeFS/blob/main/LICENSE)。", "url": "https://wpnews.pro/news/show-hn-claudefs-give-claude-ai-access-to-a-local-folder-no-local-process", "canonical_source": "https://github.com/vincentping/claudeFS", "published_at": "2026-07-29 15:36:06+00:00", "updated_at": "2026-07-29 15:52:53.460597+00:00", "lang": "en", "topics": ["ai-tools", "developer-tools"], "entities": ["Vincent Ping", "ClaudeFS", "claude.ai", "Chrome", "Edge", "Microsoft Edge Add-ons store", "Anthropic"], "alternates": {"html": "https://wpnews.pro/news/show-hn-claudefs-give-claude-ai-access-to-a-local-folder-no-local-process", "markdown": "https://wpnews.pro/news/show-hn-claudefs-give-claude-ai-access-to-a-local-folder-no-local-process.md", "text": "https://wpnews.pro/news/show-hn-claudefs-give-claude-ai-access-to-a-local-folder-no-local-process.txt", "jsonld": "https://wpnews.pro/news/show-hn-claudefs-give-claude-ai-access-to-a-local-folder-no-local-process.jsonld"}}
