🔧 Configuration

MCP Configuration for AI Assistants

To use this crawler with AI assistants like VScode Cline, configure your cline_mcp_settings.json file:

{
  "mcpServers": {
    "crawl": {
      "command": "PATH\\TO\\YOUR\\ENVIRONMENT\\.venv\\Scripts\\python.exe",
      "args": [
        "PATH\\TO\\YOUR\\PROJECT\\crawl_mcp.py"
      ],
      "disabled": false,
      "autoApprove": [],
      "timeout": 600
    }
  }
}

Replace PATH\\TO\\YOUR\\ENVIRONMENT and PATH\\TO\\YOUR\\PROJECT with the appropriate paths on your system.

Concrete Example (Windows)

{
  "mcpServers": {
    "crawl": {
      "command": "C:\\Python\\crawl4ai-mcp\\.venv\\Scripts\\python.exe",
      "args": [
        "D:\\Python\\crawl4ai-mcp\\crawl_mcp.py"
      ],
      "disabled": false,
      "autoApprove": [],
      "timeout": 600
    }
  }
}

🖥️ Usage

Usage with an AI Assistant (via MCP)

Once configured in your AI assistant, you can use the crawler by asking the assistant to perform a crawl using the following syntax:

Can you crawl the website https://example.com with a depth of 2?

The assistant will use the MCP protocol to run the crawling tool with the specified parameters.

Usage Examples with Claude

Here are examples of requests you can make to Claude after configuring the MCP tool:

• Simple Crawl: "Can you crawl the site example.com and give me a summary?"
• Crawl with Options: "Can you crawl https://example.com with a depth of 3 and include external links?"
• Crawl with Custom Output: "Can you crawl the blog example.com and save the results in a file named 'blog_analysis.md'?"

📁 Result Structure

Crawl results are saved in the crawl_results folder at the root of the project. Each result file is in Markdown format with the following structure:

# https://example.com/page

## Metadata
- Depth: 1
- Timestamp: 2023-07-01T12:34:56

## Content
Extracted content from the page...
