🚀 Getting Started with Installation

To set up the RAG Web Browser Actor MCP Server on your local machine, follow these steps:

Prerequisites

Ensure you have:

• MacOS or Windows OS.
• The latest version of Claude Desktop (or another MCP client) installed.
• Node.js (version 18 or higher).
• Apify API Token (APIFY_API_TOKEN environment variable).

Install and Configure

Step-by-Step Instructions for Configuring with Claude Desktop

1. Locate Configuration File

   • On macOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json
   • On Windows: %APPDATA%/Claude/claude_desktop_config.json

2. Modify Configuration JSON

   "mcpServers": {
     "mcp-server-rag-web-browser": {
       "command": "npx",
       "args": [
         "/path/to/mcp-server-rag-web-browser/build/index.js"
       ],
       "env": {
         "APIFY-API-TOKEN": "your-apify-api-token"
       }
     }
   }
   

3. Restart Claude Desktop

   • Quit any running instances of Claude Desktop completely.
   • Restart the application and ensure it recognizes the new MCP server.

4. Verify Connection

   • Look for an icon or notification indicating that the MCP server is connected in your Claude Desktop interface.

Local Development

To facilitate local development, run the following commands:

"mcpServers": {
    "mcp-server-rag-web-browser": {
      "command": "/path/to/mcp-server-rag-web-browser/build/index.js",
    },
    "env": {
        "APIFY-API-TOKEN": "your-apify-api-token"
    }
}

💡 Key Use Cases in AI Workflows

Debugging & Performance Improvements

For a more thorough testing environment, use the MCP Inspector to debug and monitor server performance. Here’s how to initiate it:

1. Build the Package

   npm run build
   

2. Launch MCP Inspector

   npx @modelcontextprotocol/inspector node ~/apify/mcp-server-rag-web-browser/build/index.js APIFY_API_TOKEN=your-apify-api-token
   

Upon launching, the Inspector will display a URL through which you can monitor and debug the server interaction.

Example Client Script

To test the MCP server locally using an example client:

node build/example_client.js

This script starts the server, retrieves available tools, and triggers the search tool with specified arguments.
