urlDNA

Dynamically scan and analyze potentially malicious URLs using the urlDNA.io

urlDNA MCP Server

Claude Prompt

The urlDNA MCP Server enables native tool use for security-focused LLM agents like OpenAI GPT-4.1 and Claude 3 Desktop, providing a direct interface to interact with the urlDNA threat intelligence platform via API.


Hosted MCP Server

The urlDNA MCP server is already hosted and available at:

https://mcp.urldna.io/sse

This server is accessible over Server-Sent Events (SSE) protocol, which supports streaming interactions between LLMs and the backend tools.

You can use it directly with any platform or LLM supporting the mcp specification (e.g., Claude Desktop, OpenAI GPT-4.1).


Supported Actions

The following tools are exposed by the MCP interface:

ToolDescription
new_scanSubmit a new scan for a given URL
get_scanRetrieve a scan by ID
searchSearch scans using text, domain, or filters
fast_checkLightweight phishing detection via content + redirect analysis

Integration with Claude Desktop (Anthropic MCP)

To integrate the urlDNA MCP server in Claude Desktop, update your Claude configuration (typically claude.config.json or equivalent) like so:

{
  "mcpServers": {
    "urlDNA": {
      "command": "python",
      "args": [
        "<YOUR_PATH>/run.py"
      ],
      "env": {
        "authorization": "<urlDNA_API_KEY>"
      }
    }
  }
}

Replace <YOUR_PATH> with the actual path to run.py, and <urlDNA_API_KEY> with your API key from https://urldna.io.

Once configured, you can prompt Claude with natural language requests like:

"Search in urlDNA for malicious scans with title like paypal"

Claude will automatically call the correct tool and return results from the urlDNA platform.


Using the MCP Server with OpenAI GPT-4.1 (Python SDK)

from openai import OpenAI

# Initialize OpenAI client (assumes API key is set via env var or config)
client = OpenAI()

response = client.responses.create(
    model="gpt-4.1",
    input=[
        {
            "role": "system",
            "content": [{"type": "input_text", "text": "You are a cybersecurity analyst using urlDNA."}]
        },
        {
            "role": "user",
            "content": [{"type": "input_text", "text": "Search in urlDNA malicious scan with title like paypal"}]
        }
    ],
    text={"format": {"type": "text"}},
    reasoning={},
    tools=[
        {
            "type": "mcp",
            "server_label": "urlDNA",
            "server_url": "https://mcp.urldna.io/sse",
            "headers": {
                "Authorization": "Bearer <URLDNA_API_KEY>"
            },
            "allowed_tools": ["new_scan", "get_scan", "search", "fast_check"],
            "require_approval": "never"
        }
    ],
    temperature=0.7,
    top_p=1,
    max_output_tokens=2048,
    store=True
)

print(response.output)
