01它能幫你完成什麼？
Give DeepSeek Harness computer-use MCP tools to control the desktop and Chrome
38 MCP tools (15 desktop + 23 browser) registered in DSH as `mcp__nuphus-mcp__*` — screenshots, window control, mouse/keyboard, Chrome CDP automation
Developers running DeepSeek Harness (dsh) who want their agent to operate the screen, windows and browser hands-free
Automate Chrome workflows from DSH sessions
Browser automation: navigate, snapshot (accessibility tree with `@N` refs), click, type, scroll, extract, screenshot, cookies get/set/import, tabs and downloads
Automation engineers who want an AI agent inside DeepSeek Harness to drive their own Chrome or an external fingerprint browser via CDP
Ground agent actions in what's on screen with vision and local OCR
`desktop_vision` (BYOK screenshot analysis via OpenAI-compatible or Anthropic native API) plus `desktop_perceive` (local PaddleOCR, optional YOLO icon detection) — semantic understanding plus pixel-precise coordinates
Teams building computer-use agents in DSH that need reliable element coordinates without sending screenshots to a hosted vision service
02如何將外掛接入 DeepSeek Harness？
先決條件
- Chrome or Edge installed — required for browser tools (the server auto-detects an installed browser)
- macOS only: Accessibility permission (System Settings → Privacy & Security → Accessibility) for desktop input
- Rust toolchain (stable) only if building from source with Cargo — not needed for the npm install path
安裝步驟
- 01
Install via npm (recommended, all platforms, prebuilt binaries): `npm install -g @nuphus/nuphus-mcp` — puts the `nuphus-mcp` command on your PATH, no Rust toolchain needed
$ npm install -g @nuphus/nuphus-mcp
- 02
Recommended for DSH — install the official plugin: `npx -p @deepseek-ai/dsh dsh plugin --profile web add github:mrpulor-gh/dsh-nuphus-mcp`
$ npx -p @deepseek-ai/dsh dsh plugin --profile web add github:mrpulor-gh/dsh-nuphus-mcp
- 03
Manual alternative — mount in DSH's `cordis.yml` as a stdio MCP server via `@deepseek-ai/dsh-mcp-client` (command: nuphus-mcp, args: ["--confirm-write"], toolCallTimeoutMs: 120000)
- 04
Recommended: enable strict confirmation with `--confirm-write` or `NUPHUS_MCP_CONFIRM_WRITE=1` so destructive tools require an explicit `"confirm": true` argument
驗證整合成功
- Quick smoke test: `echo '{"jsonrpc":"2.0","id":0,"method":"initialize",...}' | nuphus-mcp` — the server reads newline-delimited JSON from stdin and writes JSON-RPC responses to stdout
03DSH 整合程度與能力邊界
Official dsh-nuphus-mcp plugin mounts nuphus-mcp into DeepSeek Harness as native tools with zero config (--confirm-write on by default); manual alternative via DSH's built-in stdio MCP client
38 MCP tools over stdio (15 desktop + 23 browser)
JSON-RPC 2.0 requests from any MCP client over stdin→screenshots, window control, mouse/keyboard, clipboard, Chrome CDP automation — one binary, no daemon, no network service
tools physically control screen, windows, mouse and keyboard on the host machineComputer vision pair (desktop_vision + desktop_perceive)
screenshot of the current screen→semantic analysis from your own vision LLM (BYOK) plus local PaddleOCR text elements with pixel coordinates; optional YOLO icon detection
desktop_vision sends screenshots to your own vision LLM endpoint (BYOK API key required)first perceive call downloads OCR/YOLO models into %APPDATA%\Nuphus\models (or NUPHUS_MODELS_DIR)Chrome automation via CDP (managed or external browser)
browser tool calls; optionally NUPHUS_MCP_BROWSER_CDP_URL to attach to an external/fingerprint browser→navigate, click, type, extract, screenshot, cookies, tabs, downloads — with self-healing port re-resolution for fingerprint browsers
launches and manages a Chrome instance by default; attaches to your external browser when NUPHUS_MCP_BROWSER_CDP_URL is set (never kills it on exit)Safety-first write controls
--confirm-write flag or NUPHUS_MCP_CONFIRM_WRITE=1→destructive tools require an explicit "confirm": true argument, otherwise the tool is rejected with isError; path validation for screenshots, uploads and file drags
04適合誰？何時不該用？
適合
- Developers running DeepSeek Harness (dsh) who want their agent to operate the screen, windows and browser hands-free
- Automation engineers who want an AI agent inside DeepSeek Harness to drive their own Chrome or an external fingerprint browser via CDP
- Teams building computer-use agents in DSH that need reliable element coordinates without sending screenshots to a hosted vision service
不適合
- Desktop control is full on Windows (Win32); on macOS desktop input requires Accessibility permission; on Linux window/input capabilities are partial.
- The server can physically control the machine it runs on; by default write tools run without confirmation, so enabling --confirm-write (or NUPHUS_MCP_CONFIRM_WRITE=1) is strongly recommended.
05相容性、維護與安全提醒
- Desktop control is full on Windows (Win32); on macOS desktop input requires Accessibility permission; on Linux window/input capabilities are partial.
- The server can physically control the machine it runs on; by default write tools run without confirmation, so enabling --confirm-write (or NUPHUS_MCP_CONFIRM_WRITE=1) is strongly recommended.
- Desktop & browser automation need no API key, but desktop_vision requires a BYOK vision endpoint, and the first desktop_perceive call downloads OCR/YOLO models from the network.

06常見問題
如何把 nuphus-mcp 接入 DeepSeek Harness？
建議安裝官方 dsh-nuphus-mcp 外掛：`npx -p @deepseek-ai/dsh dsh plugin --profile web add github:mrpulor-gh/dsh-nuphus-mcp`。它會把 nuphus-mcp 以原生工具形式零設定掛載進 DSH，且預設開啟 --confirm-write。也可以在 DSH 的 cordis.yml 中透過內建的 `@deepseek-ai/dsh-mcp-client` 手動掛載為 stdio MCP 伺服器。
DSH 用的是原生工具還是一般 MCP 模式？
兩種都可以。官方外掛把 38 個工具原生掛載進 DSH；手動方式則把 nuphus-mcp 作為一般 stdio MCP 伺服器接入，工具註冊為 `mcp__nuphus-mcp__*`。無論哪種方式，都請在你想控制的機器上的桌面工作階段中執行 DSH。
需要 API key 嗎？
桌面與瀏覽器自動化都不需要。只有 `desktop_vision` 需要你自備視覺模型（BYOK，透過 NUPHUS_MCP_VISION_* 環境變數支援 OpenAI 相容或 Anthropic 原生協定）；`desktop_perceive` 在本機執行 PaddleOCR，首次呼叫時自動下載模型。
支援哪些平台？
瀏覽器工具在 Windows 與 macOS 上功能完整，Linux 可用。桌面工具在 Windows（Win32）上功能完整，macOS 需授予輔助使用權限，Linux 為部分支援。npm 提供 Windows x64/arm64、macOS arm64 與 Linux x64/arm64 的預編譯二進位檔。
如何保證寫入操作的安全？
該伺服器可以實際控制它所執行的機器。使用 `--confirm-write` 或 `NUPHUS_MCP_CONFIRM_WRITE=1` 開啟嚴格確認後，具破壞性的工具必須攜帶明確的 "confirm": true 參數才會執行；dsh 外掛預設已開啟 --confirm-write。
