onebox-dsh-bridge

English | 简体中文

A DeepSeek Harness (dsh) plugin that bridges your local dsh web to the OneBox cloud relay, so the OneBox Android app can reach your computer's AI agent over the public internet — scan-to-pair, token management and tunnel frame multiplexing, all inside the plugin. Your agent is online as soon as dsh web starts.

Built for the open-source OneBox (万宝盒) Android app. The plugin page also includes the app download info, so anyone running DSH can pair their phone in a minute.

How it works

OneBox App ⇅ https://api.wanbaohe.com/dsh/* (cloud relay)
                 ⇅ outbound WSS (control tunnel, JSON frame multiplexing)
         onebox-dsh-bridge (this plugin)
                 ⇅ loopback
         local dsh web (127.0.0.1:3080)

• Mounts a /onebox-bridge page in the dsh web GUI (self-contained HTML, zero external deps) showing the pairing QR code and online status
• Pairing: POST /dsh/pair-sessions → a ≥128-bit secret is generated locally and encoded into the QR (oneboxdsh://pair?v=1&g=…&p=…&s=…) → polls GET /dsh/pair-sessions/:id/status?s=… every 2s; once the app scans and claims, the plugin receives its device token
• Goes online via outbound WSS /dsh/agent?token=…; tunnel frames: http → local POST /api/<method> answered by http-resp; ws-open/ws-frame/ws-close bridge the local /api/events.mux|host streams
• Control WS drop → all local bridges closed, exponential-backoff reconnect (1s→30s); token 401 (revoked/expired) → local token deleted, back to scan-to-pair state
• End-to-end encryption: the pairing key travels only inside the QR code, never through the server; all app ↔ computer traffic is AES-256-GCM encrypted — the relay forwards ciphertext only

Install

With the dsh CLI installed:

dsh plugin --profile web add onebox-dsh-bridge

Running dsh from a source checkout (prefix commands with pnpm dsh, from the deepseek-harness repo root):

pnpm dsh plugin --profile web add onebox-dsh-bridge

The package declares dsh.bundle, so add automatically merges the plugin row into the profile's composition layer. Restart dsh web to take effect.

Compatibility: verified against dsh 0.1.0-rc.7 (npm latest) and 0.1.0-rc.8 (npm next) — pairing page, status API and QR pair-session creation all pass on both. The plugin must live in the web profile (it injects the webServer service that only the web composition provides).

Installing straight from GitHub also works:

dsh plugin --profile web add github:wangzhishou/onebox-dsh-bridge

Usage

1. Open http://127.0.0.1:3080/onebox-bridge in dsh web (adjust the port to your deployment)
2. In the OneBox app, open DSH Client → My Computers and scan the QR code on the page
3. Once the page shows Online, pick the device in the app and start chatting with your agent

Page buttons: Regenerate QR code (invalidates the old session and creates a new pairing session; codes expire after 10 minutes and are rebuilt automatically) and Unbind & re-pair (deletes the local token, back to waiting-for-scan).

Get the OneBox app

The plugin is the computer-side half; the phone-side half is the free, open-source OneBox Android app:

• Source code: github.com/wangzhishou/OneBox (Apache-2.0)
• International: Google Play · Official site
• 中国用户: 万宝盒官网 · 小米 / 应用宝 / OPPO / vivo / 华为应用商店搜索「万宝盒」

Configuration

All optional. Priority: environment variable > plugin config > default.

Key	Env var	Default	Description
gateway	ONEBOX_DSH_GATEWAY	https://api.wanbaohe.com	OneBox gateway. For the international app (Google Play build, api.oneboxable.com) you must set this to https://api.oneboxable.com, otherwise scanned pairings land in the CN database and the login state won't match
upstream	ONEBOX_DSH_UPSTREAM	127.0.0.1:3080	Local dsh address (host:port)
deviceName	—	system hostname	Device name reported to the app during pairing
dataDir	ONEBOX_DSH_DATA_DIR	~/.dsh/profiles/web/onebox-dsh-bridge	Token storage directory (token.json, mode 0600; old tokens are invalidated automatically after a gateway change)

To change config, override the whole row in the profile's ~/.dsh/profiles/web/cordis.patch.yml (a patch replaces the entire config value — list every key):

- id: onebox-dsh-bridge
  name: 'onebox-dsh-bridge'
  config:
    gateway: https://api.wanbaohe.com
    upstream: 127.0.0.1:3080
    deviceName: My Mac

Uninstall

dsh plugin --profile web remove onebox-dsh-bridge

Optionally delete the credentials directory ~/.dsh/profiles/web/onebox-dsh-bridge/; paired devices can be revoked in the app under My Computers.

Notes

• The /onebox-bridge page, like dsh web itself, has no extra auth (loopback-only by default); the QR code contains the pairing secret — never expose dsh web directly to the public internet
• Runtime dependencies: just ws + qrcode
