Web Crawler MCP server

This Model Control Protocol (MCP) service provides powerful tools for Cursor and Claude applications, enabling additional capabilities like web crawling. The service is designed to be easily connected to compatible applications through a simple configuration process.

Connecting to the Service

For Cursor Users

1. Open Cursor
2. Go to Settings > AI > Advanced
3. Under "MCP Endpoint", enter: https://your-render-url.onrender.com
4. Save settings and restart Cursor

For Claude App Users

1. Open Claude App
2. Go to Settings > Advanced
3. Under "MCP Connection", enter: https://your-render-url.onrender.com
4. Save settings

Available Tools

The MCP service currently provides:

• Web Crawler: This tool crawls web pages and returns the content formatted as markdown, making it easy to analyze and work with web content.

Deployment and Configuration

The MCP service runs as a Docker container on Render.com. To use the service:

1. Deploy the container on Render.com
2. Note the URL provided by Render after deployment
3. Use this URL when configuring your applications

When connecting your applications, make sure to replace your-render-url.onrender.com with the actual URL from your deployment.

Environment Variables

You can customize the server behavior with these environment variables:

• MCP_HOST: Host to bind the server (default: 0.0.0.0)
• MCP_PORT: Port to bind the server (default: 8000)

Example configuration:

MCP_HOST=0.0.0.0
MCP_PORT=9000

Service Monitoring

You can check if the service is running properly by accessing the health endpoint:

https://your-render-url.onrender.com/health

This endpoint provides status information about the service and can be used for automated monitoring.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "web-crawler" '{"command":"npx","args":["-y","web-crawler"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "web-crawler": {
            "command": "npx",
            "args": [
                "-y",
                "web-crawler"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

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

2. Add this to your configuration file:

{
    "mcpServers": {
        "web-crawler": {
            "command": "npx",
            "args": [
                "-y",
                "web-crawler"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
