01What can it help you accomplish?
Operate your real Chrome tab from DeepSeek Harness — read pages, click controls, fill forms, scroll and navigate for ai web search and browser tasks
Browser actions executed in the tab you already use, with login state, session and cookies preserved; conversation UI in the Chrome side panel
DSH users who want AI web browsing and automation on their own logged-in browser instead of a headless copy
Run text-first browser automation in dsh without any vision capability
Pages converted to structured text with a numbered inventory of interactive elements; the model addresses elements by number — screenshots never enter the pipeline
Developers building browser workflows on DeepSeek Harness who want fast, token-efficient automation without vision models
02How to install into DeepSeek Harness
Prerequisites
- Node.js `^22.19` or `>=24`
- Corepack/pnpm
- Google Chrome
Installation steps
- 01
Run the one-line installer: `curl -fsSL https://raw.githubusercontent.com/Lum1104/dsh-browser/refs/heads/main/scripts/install.sh | bash` — it downloads main, builds and registers the bridge plugin, and builds the Chrome extension into ~/.dsh/browser-extension
$ curl -fsSL https://raw.githubusercontent.com/Lum1104/dsh-browser/refs/heads/main/scripts/install.sh | bash
- 02
When the installer opens chrome://extensions, load ~/.dsh/browser-extension as an unpacked extension (first install) or click Reload (updates); restart dsh if it is already running
- 03
Start the managed installation with `cd ~/.dsh/dsh-browser && pnpm start` (or `npx @deepseek-ai/dsh web` to use the latest public dsh release)
$ npx @deepseek-ai/dsh web
- 04
Open an http:// or https:// page, click the DeepSeek whale icon, and wait for Connected
Verify the integration
- The side panel shows Connected after clicking the DeepSeek whale icon on an http:// or https:// page
- Open http://127.0.0.1:3080/ext/bridge-config — it should return JSON such as {"wsUrl":"ws://127.0.0.1:3080/ext/bridge"}; if it returns a web page instead, restart dsh and refresh
03DSH integration and capability boundaries
dsh bridge plugin + Chrome MV3 extension installed into DeepSeek Harness via a one-line installer; exposes browser tools (snapshot/click/type/scroll/navigate) inside dsh
Text-first page reading
any http:// or https:// page in the controlled Chrome tab→structured text snapshot — title, URL, main text, numbered controls, and masked form fields; `delta: true` returns only changes
read page text is sent to the selected modelInteractive control by element number
numbered inventory from browser_snapshot→clicks on links/buttons/checkboxes, React/Vue-compatible typing, keyboard events (Enter, Tab, Escape, arrows), and viewport scrolling
acts on your real browser tab; click, type, keypress, navigation, history, and reload calls fail closed until the user approves themLogin-preserving navigation
URLs, back/forward history, or reload commands in the controlled tab→navigation inside the tab you already use, retaining logins, sessions and cookies
Guarded local bridge
local dsh web server (default http://127.0.0.1:3080)→authenticated bridge connection; the extension binds tools to one user-controlled tab and probes ports 3080, 3081, 3090 automatically
privileged gateway methods such as settings.*, credentials.*, and host.open* reject non-loopback sources
04Who is it for? When not to use it?
Good for
- DSH users who want AI web browsing and automation on their own logged-in browser instead of a headless copy
- Developers building browser workflows on DeepSeek Harness who want fast, token-efficient automation without vision models
Not for
- Chrome-only: works on http:// and https:// pages; protected pages such as chrome:// and the Chrome Web Store are not supported.
- Requires Node.js ^22.19 or >=24, Corepack/pnpm and Google Chrome; not published on npm — the unscoped dsh-browser package on npm belongs to a different project, so use the repository installer.
05Compatibility, maintenance and safety notes
- Chrome-only: works on http:// and https:// pages; protected pages such as chrome:// and the Chrome Web Store are not supported.
- Requires Node.js ^22.19 or >=24, Corepack/pnpm and Google Chrome; not published on npm — the unscoped dsh-browser package on npm belongs to a different project, so use the repository installer.
- Read page text is sent to the selected model; the default auto mode reads the controlled tab without an extra prompt (ask for per-read confirmation or off to block reads). Passwords and payment-card values are masked and never leave the page.

06Frequently asked questions
How does dsh-browser integrate with DeepSeek Harness?
It ships a dsh bridge plugin plus a Chrome MV3 extension in one pnpm workspace. The one-line installer downloads main, builds and registers the bridge plugin into dsh, and builds the extension into ~/.dsh/browser-extension; you then load it in chrome://extensions and restart dsh if it is running.
Is it an MCP server or a native dsh plugin?
It is a dsh plugin (browser bridge) that registers with the running dsh web server — default http://127.0.0.1:3080 — and exposes browser tools such as browser_snapshot, browser_click, browser_type and browser_navigate, not an MCP server.
What do I need before installing?
Node.js ^22.19 or >=24, Corepack/pnpm, and Google Chrome. Local use requires no configuration; the extension probes ports 3080, 3081 and 3090 automatically. For remote or custom-port deployments, set the address and bridge token in the side panel settings.
Where does my page data go?
The model-facing pipeline is text-only — pages become structured text with numbered controls, and screenshots never enter the pipeline. Read page text is sent to the selected model, while passwords and payment-card values are always masked and never leave the page.
What are the limitations?
Only http:// and https:// pages work — protected pages such as chrome:// and the Chrome Web Store are not supported. Click, type, keypress and navigation calls fail closed until you approve them, and the assistant binds to one user-controlled tab.
