OpenCLI

1. Install OpenCLI

OpenCLI requires Node.js >= 20.

node --version
npm install -g @jackwener/opencli

2. Install the Browser Bridge Extension

OpenCLI connects to Chrome/Chromium through a lightweight Browser Bridge extension plus a small local daemon. The daemon auto-starts when needed.

Option A — Chrome Web Store (recommended): Install OpenCLI from the Chrome Web Store.

Option B — Manual install: 1. Download the latest opencli-extension-v{version}.zip from the GitHub Releases page. 2. Unzip it, open chrome://extensions, and enable Developer mode. 3. Click Load unpacked and select the unzipped folder.

3. Verify the setup

opencli doctor

Install skills (also refreshes existing installs)

npx skills add jackwener/opencli

Or install only what you need:

npx skills add jackwener/opencli --skill opencli-adapter-author
npx skills add jackwener/opencli --skill opencli-autofix
npx skills add jackwener/opencli --skill opencli-browser
npx skills add jackwener/opencli --skill opencli-usage

Quick Start

4. Optional: name your Chrome profile

Each Chrome profile runs its own OpenCLI extension instance. If you use multiple Chrome profiles, list the connected profiles and assign local aliases:

opencli profile list
opencli profile rename <contextId> work
opencli profile use work
opencli --profile work browser state

With only one connected profile, OpenCLI uses it automatically. With multiple connected profiles and no default, OpenCLI asks you to choose instead of guessing.

Configuration

opencli browser * requires an explicit <session> positional, uses a foreground browser window by default, and keeps that session's tab lease until opencli browser <session> close or idle cleanup. Browser-backed adapters use a background adapter window and release one-shot tab leases by default. Interactive adapters can declare siteSession: 'persistent' to keep a stable site tab for continuity; pass --site-session ephemeral for a one-shot tab.

CLI Hub

Unified passthrough for your existing command-line tools. Run opencli <tool> ... for any of:

gh · docker · vercel · wrangler · obsidian · longbridge · lark-cli · ntn(notion) · dws(DingTalk Workspace) · wecom-cli(企业微信) · tg(tg-cli) · discord(discord-cli) · wx(wx-cli)

Register your own with opencli external register <name>; list everything with opencli external list.

Desktop app adapters (Electron, via CDP): Cursor / Codex / Antigravity / ChatGPT App / ChatWise / Discord / Doubao — see docs/adapters/desktop/.

Plugins

Extend OpenCLI with community-contributed adapters:

opencli plugin install github:user/opencli-plugin-my-tool
opencli plugin list
opencli plugin update --all
opencli plugin uninstall my-tool

See Plugins Guide for creating your own plugin.

Troubleshooting

• "Extension not connected" — Ensure the Browser Bridge extension is installed from the Chrome Web Store and enabled in chrome://extensions.
• "attach failed: Cannot access a chrome-extension:// URL" — Another extension may be interfering. Try disabling other extensions temporarily.
• Empty data or 'Unauthorized' error — Your Chrome/Chromium login session may have expired. Navigate to the target site and log in again.
• Node API errors / missing fetch / startup crash on old Node — OpenCLI requires Node.js >= 20. Run node --version, upgrade Node if needed, then retry.
