OpenCLI

Make any website your CLI. Reuse Chrome login, zero risk, AI-powered discovery.

Install & Run

cd ~/code/opencli
npm install

# Run via source
npx tsx src/main.ts <command>

# Or build first
npm run build && node dist/main.js <command>

Prerequisites

Browser commands require:

1. Chrome browser running (logged into target sites)
2. Playwright MCP Bridge extension
3. Click extension icon to approve connection (or set PLAYWRIGHT_MCP_EXTENSION_TOKEN)

Public API commands (hackernews, github search, v2ex) need no browser.

opencli validate bilibili   # Validate specific site

AI Agent Workflow

# Deep Explore: network intercept → response analysis → capability inference
opencli explore <url> --site <name>

# Synthesize: generate evaluate-based YAML pipelines from explore artifacts
opencli synthesize <site>

# Generate: one-shot explore → synthesize → register
opencli generate <url> --goal "hot"

# Strategy Cascade: auto-probe PUBLIC → COOKIE → HEADER
opencli cascade <api-url>

# Verify: smoke-test a generated adapter
opencli verify <site/name> --smoke

Output Formats

All commands support --format / -f:

opencli bilibili hot -f table   # Default: rich table
opencli bilibili hot -f json    # JSON (pipe to jq, feed to AI agent)
opencli bilibili hot -f md      # Markdown
opencli bilibili hot -f csv     # CSV

Verbose Mode

opencli bilibili hot -v         # Show each pipeline step and data flow

Creating Adapters

YAML Pipeline (declarative, recommended)

Create src/clis/<site>/<name>.yaml:

site: mysite
name: hot
description: Hot topics
domain: www.mysite.com
strategy: cookie        # public | cookie | header | intercept | ui
browser: true

args:
  limit:
    type: int
    default: 20
    description: Number of items

pipeline:
  - navigate: https://www.mysite.com

  - evaluate: |
      (async () => {
        const res = await fetch('/api/hot', { credentials: 'include' });
        const d = await res.json();
        return d.data.items.map(item => ({
          title: item.title,
          score: item.score,
        }));
      })()

  - map:
      rank: ${{ index + 1 }}
      title: ${{ item.title }}
      score: ${{ item.score }}

  - limit: ${{ args.limit }}

columns: [rank, title, score]

For public APIs (no browser):

strategy: public
browser: false

pipeline:
  - fetch:
      url: https://api.example.com/hot.json
  - select: data.items
  - map:
      title: ${{ item.title }}
  - limit: ${{ args.limit }}

TypeScript Adapter (programmatic)

Create src/clis/<site>/<name>.ts and import in clis/index.ts:

import { cli, Strategy } from '../../registry.js';

cli({
  site: 'mysite',
  name: 'search',
  strategy: Strategy.COOKIE,
  args: [{ name: 'keyword', required: true }],
  columns: ['rank', 'title', 'url'],
  func: async (page, kwargs) => {
    await page.goto('https://www.mysite.com');
    const data = await page.evaluate(`
      (async () => {
        const res = await fetch('/api/search?q=${kwargs.keyword}', {
          credentials: 'include'
        });
        return await res.json();
      })()
    `);
    return data.items.map((item, i) => ({
      rank: i + 1, title: item.title, url: item.url,
    }));
  },
});

When to use TS: XHR interception (小红书), cookie extraction (Twitter ct0), Wbi signing (Bilibili), auto-pagination, complex data transforms.

Pipeline Steps

Step	Description	Example
navigate	Go to URL	navigate: https://example.com
fetch	HTTP request (browser cookies)	fetch: { url: "...", params: { q: "..." } }
evaluate	Run JavaScript in page	evaluate: | (async () => { ... })()
select	Extract JSON path	select: data.items
map	Map fields	map: { title: "${{ item.title }}" }
filter	Filter items	filter: item.score > 100
sort	Sort items	sort: { by: score, order: desc }
limit	Cap result count	limit: ${{ args.limit }}
intercept	Declarative XHR capture	intercept: { trigger: "navigate:...", capture: "api/hot" }
snapshot	Page accessibility tree	snapshot: { interactive: true }
click	Click element	click: ${{ ref }}
type	Type text	type: { ref: "@1", text: "hello" }
wait	Wait for time/text	wait: 2 or wait: { text: "loaded" }
press	Press key	press: Enter

Template Syntax

# Arguments with defaults
${{ args.keyword }}
${{ args.limit | default(20) }}

# Current item (in map/filter)
${{ item.title }}
${{ item.data.nested.field }}

# Index (0-based)
${{ index }}
${{ index + 1 }}

5-Tier Authentication Strategy

Tier	Name	Method	Example
1	public	No auth, Node.js fetch	Hacker News, V2EX
2	cookie	Browser fetch with credentials: include	Bilibili, Zhihu
3	header	Custom headers (ct0, Bearer)	Twitter GraphQL
4	intercept	XHR interception + store mutation	小红书 Pinia
5	ui	Full UI automation (click/type/scroll)	Last resort

Environment Variables

Variable	Default	Description
OPENCLI_BROWSER_CONNECT_TIMEOUT	30	Browser connection timeout (sec)
OPENCLI_BROWSER_COMMAND_TIMEOUT	45	Command execution timeout (sec)
OPENCLI_BROWSER_EXPLORE_TIMEOUT	120	Explore timeout (sec)
OPENCLI_EXTENSION_LOCK_TIMEOUT	120	Extension lock timeout (sec)
PLAYWRIGHT_MCP_EXTENSION_TOKEN	—	Auto-approve extension connection

Troubleshooting

Issue	Solution
npx not found	Install Node.js: brew install node
Timed out connecting to browser	1) Chrome must be open 2) Install MCP Bridge extension 3) Click to approve
Extension lock timed out	Another opencli command is running; browser commands run serially
Target page context error	Add navigate: step before evaluate: in YAML
Empty table data	Check if evaluate returns JSON string (MCP parsing) or data path is wrong
