OpenCLI

Turn websites into CLI commands while reusing an existing Chrome login session when needed.

When to Use

• You need data from a website that already works in the browser but does not expose a clean public API.
• You want browser-backed extraction without exporting credentials out of Chrome.
• You want structured output from a website in table, json, md, or csv.
• You want to explore a site, generate an adapter, probe auth strategy, or smoke-test a generated workflow.

Install

npm install -g @jackwener/opencli
opencli list

Prerequisites

Browser-backed commands require:

1. Chrome running and already logged into the target site
2. Playwright MCP Bridge installed
3. PLAYWRIGHT_MCP_EXTENSION_TOKEN configured for the Playwright MCP server

Public API commands such as hackernews, v2ex, and some github search flows do not need the browser setup.

Core Usage

opencli <site> <command> [flags]
opencli list
opencli list --json
opencli hackernews top --limit 5 -f json
opencli bilibili hot --limit 10
opencli github search --keyword "cli"

AI-Native Workflows

opencli explore <url> --site <name>
opencli synthesize <site>
opencli generate <url> --goal "hot"
opencli cascade <api-url>
opencli verify <site/name> --smoke

• explore: inspect a site and capture artifacts for later generation
• synthesize: generate adapters from existing explore artifacts
• generate: run the end-to-end explore to register flow in one step
• cascade: auto-probe auth strategy from public to cookie to header
• verify: smoke-test a generated adapter

If you need to build new adapters, read references/cli-creator.md.

Output And Debugging

opencli <site> <command> -f table
opencli <site> <command> -f json
opencli <site> <command> -f md
opencli <site> <command> -f csv
opencli <site> <command> -v

Common Targets

• Browser-backed: bilibili, zhihu, xiaohongshu, twitter, reddit, weibo, youtube, boss, yahoo-finance, reuters, smzdm, ctrip
• Public or mixed: hackernews, v2ex, github, bbc

Notes

• Tabs opened during execution are usually auto-closed afterwards.
• If a browser command returns empty data, first verify the site is reachable in Chrome and the session is logged in.
