just-every/mcp-read-website-fast: Quickly reads webpages and converts to markdown for fast, token efficient web scraping

Fast, token-efficient web content extraction for AI agents - converts websites to clean Markdown.

Existing MCP web crawlers are slow and consume large quantities of tokens. This pauses the development process and provides incomplete results as LLMs need to parse whole web pages.

This MCP package fetches web pages locally, strips noise, and converts content to clean Markdown while preserving links. Designed for Claude Code, IDEs and LLM pipelines with minimal token footprint. Crawl sites locally with minimal dependencies.

Note: This package now uses @just-every/crawl for its core crawling and markdown conversion functionality.

• Fast startup using official MCP SDK with lazy loading for optimal performance
• Content extraction using Mozilla Readability (same as Firefox Reader View)
• HTML to Markdown conversion with Turndown + GFM support
• Smart caching with SHA-256 hashed URLs
• Polite crawling with robots.txt support and rate limiting
• Concurrent fetching with configurable depth crawling
• Stream-first design for low memory usage
• Link preservation for knowledge graphs
• Optional chunking for downstream processing

Settings → Tools → AI Assistant → Model Context Protocol (MCP) → Add

Choose “As JSON” and paste:

{"command":"npx","args":["-y","@just-every/mcp-read-website-fast"]}

Or, in the chat window, type /add and fill in the same JSON—both paths land the server in a single step. 

{
  "mcpServers": {
    "read-website-fast": {
      "command": "npx",
      "args": ["-y", "@just-every/mcp-read-website-fast"]
    }
  }
}

Drop this into your client’s mcp.json (e.g. .vscode/mcp.json, ~/.cursor/mcp.json, or .mcp.json for Claude).

• read_website - Fetches a webpage and converts it to clean markdown
  • Parameters:
    • url (required): The HTTP/HTTPS URL to fetch
    • pages (optional): Maximum number of pages to crawl (default: 1, max: 100)

• read-website-fast://status - Get cache statistics
• read-website-fast://clear-cache - Clear the cache directory

npm install
npm run build

npm run dev fetch https://example.com/article

npm run dev fetch https://example.com --depth 2 --concurrency 5

# Markdown only (default)
npm run dev fetch https://example.com

# JSON output with metadata
npm run dev fetch https://example.com --output json

# Both URL and markdown
npm run dev fetch https://example.com --output both

• -p, --pages <number> - Maximum number of pages to crawl (default: 1)
• -c, --concurrency <number> - Max concurrent requests (default: 3)
• --no-robots - Ignore robots.txt
• --all-origins - Allow cross-origin crawling
• -u, --user-agent <string> - Custom user agent
• --cache-dir <path> - Cache directory (default: .cache)
• -t, --timeout <ms> - Request timeout in milliseconds (default: 30000)
• -o, --output <format> - Output format: json, markdown, or both (default: markdown)

The MCP server includes automatic restart capability by default for improved reliability:

• Automatically restarts the server if it crashes
• Handles unhandled exceptions and promise rejections
• Implements exponential backoff (max 10 attempts in 1 minute)
• Logs all restart attempts for monitoring
• Gracefully handles shutdown signals (SIGINT, SIGTERM)

For development/debugging without auto-restart:

# Run directly without restart wrapper
npm run serve:dev
