How to install and run CRAWL4AI_MCP

Installation

The simplest and recommended way to use this tool is via uvx, which automatically fetches and runs the latest published version from PyPI without polluting your global environment.

Install Prerequisites

Ensure you have the following installed on your system:

  • uv (The blazing fast Python package manager)
  • Python 3.13+ (Highly recommended, especially for Windows users)

Run the Server

You can run the server directly without installing it globally using uvx:

uvx crawl4ai-mcp-llm

Windows users: If you have multiple Python versions, force the use of 3.13 to avoid async loop issues: uvx --python 3.13 crawl4ai-mcp-llm

Install Playwright Browsers

For the "Magic Mode" and JavaScript rendering features to work properly, you must install the Chromium browser binaries for Playwright. Run the following command in your terminal:

playwright install chromium

All set! Once installed, your server is ready to perform advanced, bot-bypassing web crawling.
