README

webclaw

Turn websites into clean markdown, JSON, and LLM-ready context.
_{CLI, MCP server, REST API, and SDKs for AI agents and RAG pipelines.}

Most web scraping tools give your agent one of two bad outputs:

a blocked page, login wall, or empty app shell
raw HTML full of nav, scripts, styling, ads, and duplicated boilerplate

webclaw.io is the hosted web extraction API for webclaw. This repo contains the open-source CLI, MCP server, extraction engine, and self-hostable server.

webclaw turns a URL into clean content your tools can actually use.

webclaw https://example.com --format markdown

# Example Domain

This domain is for use in illustrative examples in documents.

You may use this domain in literature without prior coordination or asking for permission.

Use it from the terminal, wire it into Claude/Cursor through MCP, call the hosted API from your app, or self-host the OSS server.

Install

Agent setup

The fastest way to connect webclaw to Claude Code, Claude Desktop, Cursor, Windsurf, OpenCode, Codex CLI, and other MCP-compatible tools:

npx create-webclaw

The installer detects supported clients and configures the MCP server for you.

Homebrew

brew tap 0xMassi/webclaw
brew install webclaw
