CLI-Anything-Web is a Claude Code plugin that generates production-grade Python CLIs for any web application by capturing its live HTTP traffic. Point it at a URL, and get a fully working CLI on your PATH — with auth, REPL mode, --json output, and tests.
[!WARNING]
Experimental Project — Use Responsibly
This project uses undocumented web APIs reverse-engineered from live HTTP traffic. These APIs can change without notice.
- Not affiliated with any website — This is an independent open-source project
- APIs may break — Websites can change their internal endpoints, HTML structure, or add protections at any time
- Respect rate limits — Generated CLIs include exponential backoff, but heavy usage may be throttled
- For personal use — Best suited for prototyping, automation, research, and personal productivity
Generated CLIs interact with real production services. Use them responsibly and in accordance with each website's terms of service.
💡 The Idea
Most web apps don't have public APIs. CLI-Anything-Web changes that:
No API docs needed. No reverse-engineering by hand. Just point and generate.
🚀 Quick Start
Prerequisites
| Requirement | Version | Why |
|---|
| Claude Code | With plugin support | Runs the generation pipeline |
| Node.js | 18+ | For playwright traffic capture |
| Python | 3.10+ | Generated CLIs are Python |
Install the Plugin
# Inside Claude Code
/plugin marketplace add ItamarZand88/CLI-Anything-WEB
/plugin install cli-anything-web
/reload-plugins
Generate Your First CLI
/cli-anything-web https://your-favorite-website.com
The agent opens a browser, asks you to log in if needed, captures traffic, and generates a complete CLI. That's it.
📦 Examples

Try them yourself
# Install the entire fleet (every CLI) in one command:
pip install cli-anything-web # or: uv tool install cli-anything-web
# ...or install only the CLIs you want, by name (see the table above):
pip install cli-web-futbin
uvx cli-web-futbin --help # or run it once, no install, via uvx
Working from a clone instead? Install a CLI editable with pip install -e <app>/agent-harness (see QUICKSTART).

Agent-Native: Claude uses the CLIs automatically
Every generated CLI comes with a skill file (.claude/skills/<app>-cli/SKILL.md) that Claude Code loads automatically. The skill tells Claude exactly how to use the CLI — every command, every option, every output format. When you ask Claude a question like "find me a hotel in Paris", it reads the booking skill and runs cli-web-booking search find "Paris" on its own.
Each skill includes:
- All available commands with arguments and options
- Output format for each command
- Auth requirements and setup instructions
- Common agent patterns (piping, filtering, chaining commands)
MCP Server Mode: every CLI is also an MCP server
Every generated CLI doubles as a Model Context Protocol server — run
cli-web-<app> mcp-serve and any MCP client (Claude Desktop, IDEs, other
agents) gets every command as a typed MCP tool, with input schemas derived
from the CLI's own options and the standard --json envelope as tool output:
// e.g. in an MCP client config
{
"mcpServers": {
"hackernews": { "command": "cli-web-hackernews", "args": ["mcp-serve"] }
}
}
No extra dependencies, no separate server code — the adapter walks the Click
command tree at startup, so new commands automatically become new tools.
Every CLI also ships a doctor command (cli-web-<app> doctor [--json])
that diagnoses the local setup — install, Python version, auth file and its
permissions, optional dependencies — before you ever need to open an issue.
⚙️ How It Works
The plugin runs a 4-phase pipeline, fully automated by Claude:
| Phase | What Happens |
|---|
| 1. Capture | Opens browser via Playwright, records all HTTP traffic while you use the site |
| 2. Analyze & Generate | Identifies protocol (REST/GraphQL/RPC/HTML), maps endpoints, generates full Python CLI |
| 3. Test | Writes unit tests (mocked) + E2E tests (live API) + subprocess tests |
| 4. Publish | pip install -e . → on your PATH → smoke tested → Claude skill generated |
🔧 What Every Generated CLI Includes
| Feature | Details |
|---|
| Click commands | cli-web-<app> <group> <command> [options] |
| Interactive REPL | Run with no args — history, autocomplete, branded prompt |
--json output | Machine-readable on every command — pipe into jq, scripts, or agents |
| Auth management | Python Playwright browser login → cookie extraction → auth.json |
| Error handling | Typed exceptions → structured JSON errors: {"error": true, "code": "AUTH_EXPIRED"} |
| Tests | Unit (mocked HTTP) + E2E (live API) + subprocess (_resolve_cli) |
| Installable | pip install -e . puts it on your PATH immediately |
📋 Commands
| Command | Description |
|---|
/cli-anything-web <url> | Full pipeline — capture, analyze, generate, publish |
/cli-anything-web:record <url> | Capture traffic only (for exploration) |
/cli-anything-web:refine <path> | Add more commands to an existing CLI |
/cli-anything-web:test <path> | Run tests and update TEST.md |
/cli-anything-web:validate <path> | Validate against 75-check quality standards |
/cli-anything-web:list | List all generated CLIs |
🌐 Supported Protocols
The plugin auto-detects and handles multiple web architectures:
| Protocol | Example Sites | How It's Handled |
|---|
| REST / JSON API | Monday.com, Dev.to | httpx client, JSON response parsing |
| Server-rendered HTML | GitHub, FUTBIN, Hacker News | BeautifulSoup4 + CSS selectors |
| Anti-bot (curl_cffi) | Product Hunt, Reddit, Amazon | curl_cffi with Chrome TLS impersonation |
| JS proof-of-work challenge | Unsplash, ChatGPT | camoufox (stealth headless Firefox) solves the challenge |
| GraphQL | Shopify, GitHub API v4 | Query abstraction into CLI commands |
| GraphQL + AWS WAF | Booking.com | curl_cffi + WAF cookie bypass |
| Google batchexecute | NotebookLM, Google Docs, Keep | Custom RPC encoder/decoder |
| Browser-rendered (Playwright) | Google AI Mode | Headless browser rendering + content extraction |

🔗 Inspiration
This project is directly inspired by CLI-Anything by HKUDS — a Claude Code plugin that makes desktop software (GIMP, Blender, LibreOffice, OBS Studio) agent-native by analyzing source code and generating CLI wrappers.
CLI-Anything-Web extends the same vision to the web — where there's no source code to analyze, only live HTTP traffic to capture.
| CLI-Anything | CLI-Anything-Web |
|---|
| Target | Desktop apps (GIMP, Blender, OBS) | Web apps (NotebookLM, Booking.com, any website) |
| Input | Source code, GUI APIs, plugin systems | Live HTTP traffic from browser |
| Analysis | Static code analysis + API mapping | Network traffic capture + protocol detection |
| Auth | N/A (local software) | Browser login, cookies, WAF bypass, API keys |
| Output | Click CLI + REPL + --json + tests | Click CLI + REPL + --json + tests |
Together they cover the full spectrum: CLI-Anything for desktop, CLI-Anything-Web for the web.
🗺️ What's Next
We're actively building more CLIs and improving the plugin:
- 🎯 More CLIs — Jira, Notion, Monday.com, Spotify
- 🎵 Content generation — Suno, ElevenLabs, Midjourney
- 🧠 Smarter analysis — Auto-detect auth flows, pagination, WebSocket streams
- 🔄 CI/CD integration — Run CLIs in GitHub Actions with env-var auth
- 📦 Community registry — Share and install CLIs built by other users
