📦 Installation

Prerequisites

• uv (Python package manager)

• Chrome/Chromium browser (for Selenium)

• OpenAI API key (for Q&A functionality)

🚀 Quick Start with uv (Recommended)

# Clone the repository
git clone https://github.com/kimdonghwi94/web-analyzer-mcp.git
cd web-analyzer-mcp

# Run directly with uv (auto-installs dependencies)
uv run mcp-webanalyzer

Installing via Smithery

To install web-analyzer-mcp for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @kimdonghwi94/web-analyzer-mcp --client claude

IDE/Editor Integration

Add to your Claude Desktop_config.json file. See Claude Desktop MCP documentation for more details.

  "mcpServers": {
    "web-analyzer": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/web-analyzer-mcp",
        "run", 
        "mcp-webanalyzer"
      ],

    }
  }
}

Add the server using Claude Code CLI:

claude mcp add web-analyzer -e OPENAI_API_KEY=your_api_key_here -e OPENAI_MODEL=gpt-4 -- uv --directory /path/to/web-analyzer-mcp run mcp-webanalyzer

Add to your Cursor settings (File > Preferences > Settings > Extensions > MCP):

{
  "mcpServers": {
    "web-analyzer": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/web-analyzer-mcp",
        "run", 
        "mcp-webanalyzer"
      ],
      "env": {
