CRW Web Scraper (fastCRW) is an open-source web scraping and search MCP server written in Rust, offering scrape, crawl, map, search, and extract capabilities with a Firecrawl-compatible /scrape, /crawl, /search API. It emphasizes a single low-memory binary and self-hosting, while also offering a managed cloud option, making it a fit for developers who want data control and AI-agent integration. Note that it is not an official Firecrawl, Tavily, or Anthropic project, the engine is AGPL-3.0 licensed, and usage must respect target site policies and robots.txt.
CRW Web Scraper (fastCRW) is an open-source web scraper, crawler, and search tool written in Rust, packaged with an MCP server for AI agents. It turns URLs into clean Markdown or structured JSON and covers scrape, crawl, map, search, and extract operations. It exposes a Firecrawl-compatible API (/scrape, /crawl, /search) and can be self-hosted as a single binary (about 6 MB RAM) or used through a managed cloud service. The engine and MCP server are licensed AGPL-3.0, while the Python and TypeScript SDKs are MIT. It is not maintained by Firecrawl, Tavily, or Anthropic.
Option 1 (one-command install): run curl -fsSL https://fastcrw.com/install | sh; local use requires no account. To use the cloud, pass your key in the same command: curl -fsSL https://fastcrw.com/install | CRW_API_KEY=crw_live_... sh, which also registers the MCP server with detected AI coding tools. Option 2 (MCP-only install): run npx -y crw-mcp@latest install to install the CRW skill and MCP server in detected tools. You can also run crw setup on its own for interactive configuration. Container option: use image ghcr.io/us/crw:latest with stdio transport and the positional argument crw-mcp.
