Highlights

• Account-safe — Reuses Chrome's logged-in state; your credentials never leave the browser.
• AI Agent ready — explore discovers APIs, synthesize generates adapters, cascade finds auth strategies.
• Dynamic Loader — Simply drop .ts or .yaml adapters into the clis/ folder for auto-registration.
• Dual-Engine Architecture — Supports both YAML declarative data pipelines and robust browser runtime typescript injections.

Prerequisites

• Node.js: >= 18.0.0
• Chrome running and logged into the target site (e.g. bilibili.com, zhihu.com, xiaohongshu.com).

⚠️ Important: Browser commands reuse your Chrome login session. You must be logged into the target website in Chrome before running commands. If you get empty data or errors, check your login status first.

OpenCLI connects to your browser through the Playwright MCP Bridge extension.

Playwright MCP Bridge Extension Setup

1. Install Playwright MCP Bridge extension in Chrome.
2. Obtain your token by clicking the extension icon in the browser toolbar or from the extension settings page.

You must configure this token in BOTH your MCP configuration AND system environment variables.

First, add it to your MCP client config (e.g. Claude/Cursor):

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": ["-y", "@playwright/mcp@latest", "--extension"],
      "env": {
        "PLAYWRIGHT_MCP_EXTENSION_TOKEN": "<your-token-here>"
      }
    }
  }
}

And, so that opencli commands can use it directly in the terminal, export it in your shell environment (e.g. ~/.zshrc):

export PLAYWRIGHT_MCP_EXTENSION_TOKEN="<your-token-here>"

Quick Start

Install via npm (recommended)

npm install -g @jackwener/opencli

Then use directly:

opencli list                              # See all commands
opencli list -f yaml                      # List commands as YAML
opencli hackernews top --limit 5          # Public API, no browser
opencli bilibili hot --limit 5            # Browser command
opencli zhihu hot -f json                 # JSON output
opencli zhihu hot -f yaml                 # YAML output

Install from source (for developers)

git clone git@github.com:jackwener/opencli.git
cd opencli 
npm install
npm run build
npm link      # Link binary globally
opencli list  # Now you can use it anywhere!

Update

npm install -g @jackwener/opencli@latest

Output Formats

All built-in commands support --format / -f with table, json, yaml, md, and csv. The list command supports the same format options, and keeps --json for backward compatibility.

opencli list -f yaml            # Command registry as YAML
opencli bilibili hot -f table   # Default: rich terminal table
opencli bilibili hot -f json    # JSON (pipe to jq or LLMs)
opencli bilibili hot -f yaml    # YAML (human-readable structured output)
opencli bilibili hot -f md      # Markdown
opencli bilibili hot -f csv     # CSV
opencli bilibili hot -v         # Verbose: show pipeline debug steps

For AI Agents (Developer Guide)

If you are an AI assistant tasked with creating a new command adapter for opencli, please follow the AI Agent workflow below:

Quick mode: To generate a single command for a specific page URL, see CLI-ONESHOT.md — just a URL + one-line goal, 4 steps done.

Full mode: Before writing any adapter code, read CLI-EXPLORER.md. It contains the complete browser exploration workflow, the 5-tier authentication strategy decision tree, and debugging guide.

# 1. Deep Explore — discover APIs, infer capabilities, detect framework
opencli explore https://example.com --site mysite

# 2. Synthesize — generate YAML adapters from explore artifacts
opencli synthesize mysite

# 3. Generate — one-shot: explore → synthesize → register
opencli generate https://example.com --goal "hot"

# 4. Strategy Cascade — auto-probe: PUBLIC → COOKIE → HEADER
opencli cascade https://api.example.com/data

Explore outputs to .opencli/explore/<site>/ (manifest.json, endpoints.json, capabilities.json, auth.json).

Troubleshooting

• "Failed to connect to Playwright MCP Bridge"
  • Ensure the Playwright MCP extension is installed and enabled in your running Chrome.
  • Restart the Chrome browser if you just installed the extension.
• Empty data returns or 'Unauthorized' error
  • Your login session in Chrome might have expired. Open a normal Chrome tab, navigate to the target site, and log in or refresh the page to prove you are human.
• Node API errors
  • Make sure you are using Node.js >= 18. Some dependencies require modern Node APIs.

Releasing New Versions

npm version patch   # 0.1.0 → 0.1.1
npm version minor   # 0.1.0 → 0.2.0
git push --follow-tags

The CI will automatically build, create a GitHub release, and publish to npm.
