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.
FIFA World Cup 2026 — fixtures, nations, squads, group standings, and bookmaker odds (read-only)
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).
# Required browsers
playwright install chromium # for CLIs that require browser-based auth or rendering
python -m camoufox fetch # for CLIs that use stealth browser (anti-bot bypass)
pip install "cli-web-linkedin[browser]"
cli-web-linkedin auth login # required — browser-based LinkedIn SSO
# Search people and jobs
cli-web-linkedin search people "python developer" --limit 5 --json
cli-web-linkedin jobs search "software engineer" --json
# View feed, profile, connections
cli-web-linkedin feed --count 5 --json
cli-web-linkedin profile me --json
cli-web-linkedin network connections --limit 10 --json
Capitol Trades — US congressional stock trades (no auth, CloudFront bypass)
pip install cli-web-capitoltrades
# Latest trades across Congress
cli-web-capitoltrades --json trades list --page-size 20
# Trades for a specific ticker
cli-web-capitoltrades --json trades by-ticker NVDA
# Top politicians by trade volume
cli-web-capitoltrades --json politicians top --by trades --page-size 10
# Rich issuer data with 1-year price history
cli-web-capitoltrades --json issuers search nvidia
YouTube — videos, channels, trending, and transcripts (no auth)
World Cup 2026 — fixtures, teams, rosters, and standings (no auth)
pip install cli-web-worldcup
cli-web-worldcup fixtures list --limit 5 --json
cli-web-worldcup teams list --json
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
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.
