CLI-Anything-WEB: Open-source plugin that reverse-engineers any website into a Python CLI for Claude Code
CLI-Anything-WEB is a new open-source plugin for Claude Code that automatically turns any website into a Python CLI. The plugin monitors your browser traffic as you interact with a site, captures all HTTP requests/responses, reverse-engineers the protocol, and generates a complete CLI tool — including authentication handling, test generation, and --json output everywhere.
Once generated, each CLI includes a SKILL.md file so Claude can invoke the tool autonomously without extra prompting. For example, you can ask Claude "find me a hotel in Paris under 200" and it will run the generated Booking.com CLI on its own.
Key technical details
- Protocol extraction: Captures HTTP traffic from your browser, deduces the underlying API protocol, and generates a Python CLI from it.
- Auth handling: Manages cookie refresh without user interaction — a hard problem the author had to solve.
- Bypass challenges: The plugin handles Cloudflare and AWS WAF challenges, and can decode Google's
batchexecuteRPC protocol. - 19 sample CLIs: The repo ships with working CLIs for Reddit, NotebookLM, Booking, Airbnb, ChatGPT, Stitch, Capitol Trades, LinkedIn, and others — so you can see how different protocols are handled.
The project is MIT-licensed, open source, and unaffiliated with any of the target websites. Repository: https://github.com/ItamarZand88/CLI-Anything-WEB
The author is actively seeking feedback on which sites to target next.
