@webclaw/mcp

Clean web access for AI agents, over MCP. Turn any URL into markdown, JSON, or LLM-ready context — including pages that block bots or need JavaScript — straight from Claude, Cursor, and any MCP client.

Zero-install launcher for the webclaw MCP server. npx @webclaw/mcp downloads a prebuilt webclaw-mcp binary once (verified against the release SHA256SUMS), caches it, and runs it as an MCP stdio server. No Rust build, no global install. It runs on your machine; the hosted webclaw cloud is used only for the tools that need it, and only when you set WEBCLAW_API_KEY.

Add to your MCP client

Point any stdio MCP client at the npx command — Claude Desktop, Cursor, Windsurf, Antigravity (mcpServers JSON):

{
  "mcpServers": {
    "webclaw": {
      "command": "npx",
      "args": ["-y", "@webclaw/mcp"]
    }
  }
}

Add a key to unlock the cloud-backed tools (bot-protection bypass, JS rendering, web search, research):

{
  "mcpServers": {
    "webclaw": {
      "command": "npx",
      "args": ["-y", "@webclaw/mcp"],
      "env": { "WEBCLAW_API_KEY": "wc_your_key" }
    }
  }
}

Claude Code:

claude mcp add webclaw -- npx -y @webclaw/mcp

Or run npx create-webclaw to auto-detect your AI tools and write their configs for you.

Tools (12)

scrape, search, crawl, map, batch, extract, summarize, diff, brand, research, plus list_extractors / vertical_scrape for 30+ site-specific extractors (Amazon, GitHub, Reddit, YouTube, npm, PyPI, and more).

• No key needed: scrape, crawl, map, batch, diff, brand, list_extractors, vertical_scrape.
• Needs an LLM (local Ollama or a provider key): extract, summarize.
• Needs WEBCLAW_API_KEY: research, and search when SERPER_API_KEY is unset — plus automatic bot-protection bypass and JS rendering for the fetch tools.
