URLScan MCP server for AI agents

The Claude MCP Server provides a streamlined way to scan URLs for potential security threats using the Model Context Protocol (MCP). It integrates with the urlscan.io API to retrieve comprehensive scan results for any URLs you specify.

Installation

Setting up the Claude MCP Server is straightforward:

Clone the repository to your local machine:

git clone <repository-url>
cd <repository-directory>

Install the required dependencies using npm:
```
npm install
```

Configuration

To integrate the server with Claude Desktop, you'll need to update your Claude Desktop configuration file with the following entry:

"scan-url": {
    "command": "node",
    "args": [
        "src/index.js FILEPATH"
    ]
}

This configuration allows Claude to utilize the URL scanning functionality through simple commands.

Usage

Once installed and configured, you can use the MCP server to scan URLs directly through Claude Desktop. The server will process the URL, send it to urlscan.io, and return the scan results.

The server handles all the communication with the urlscan.io API, making it simple to check URLs for potential security issues or gather information about websites without leaving your Claude interface.

How to add this MCP server to 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 > MCP and click "Add new global MCP server".

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

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

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 explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
