Connecting to the Remote MCP Server

Using Clients with Native Support

If your MCP client directly supports remote MCP servers:

Enter the server URL https://radar.mcp.cloudflare.com when prompted
Complete the authentication flow
Start using the available tools

Using Clients Without Native Support

For clients without built-in remote server support:

Install the mcp-remote package:
```
npm install mcp-remote
```

Create or update your client's configuration file with:

{
  "mcpServers": {
    "cloudflare": {
      "command": "npx",
      "args": ["mcp-remote", "https://radar.mcp.cloudflare.com/sse"]
    }
  }
}

Restart your MCP client
Complete the OAuth authentication flow in the browser window that opens
The Cloudflare Radar tools will now be available in your client

Usage Examples

Here are some example prompts you can use with the server:

What are the most used operating systems?
What are the top 5 ASes in Portugal?
Get information about ASN 13335.
What are the details of IP address 1.1.1.1?
List me traffic anomalies in Syria over the last year.
Compare domain rankings in the US and UK.
Give me rank details for google.com in March 2025.
Scan https://example.com.
Show me HTTP traffic trends from Portugal.

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.
