URLhaus MCP Server

A comprehensive Model Context Protocol (MCP) server that provides access to URLhaus, a project from abuse.ch that collects and shares malicious URLs used for malware distribution. This server enables AI agents to perform threat intelligence research and cybersecurity analysis through the URLhaus database.

Features

This MCP server provides the following tools for querying URLhaus data:

URL Analysis Tools

• get_recent_urls: Get the most recent malicious URLs from URLhaus

• lookup_url: Get detailed information about a specific URL

• search_urls: Search for URLs by various criteria (host, URL, tag, or signature)

Host/Domain Analysis Tools

• lookup_host: Get information about URLs hosted on a specific host/domain

Malware Analysis Tools

• lookup_payload: Get information about a malware payload by its hash

• get_payloads: Get recent malware payloads from URLhaus

• get_urls_by_tag: Get URLs associated with a specific malware tag/family

• get_urls_by_signature: Get URLs associated with a specific malware signature

Installation

From GitHub

1. Clone the repository:

   git clone https://github.com/Cyreslab-AI/urlhaus-mcp-server.git
   cd urlhaus-mcp-server

2. Install dependencies:

   npm install

3. Build the server:

   npm run build

From npm (Coming Soon)

npm install -g urlhaus-mcp-server

Configuration

Auth-Key (required)

As of abuse.ch's "Community First" changes (effective 2025-06-30), every request to the URLhaus API must carry an Auth-Key HTTP header. Without it, the API rejects requests. Get a free key at auth.abuse.ch, then set it as the URLHAUS_AUTH_KEY environment variable. This server will not start without it.

Add the server to your MCP settings configuration:

{
  "mcpServers": {
    "urlhaus": {
      "command": "node",
      "args": ["/path/to/urlhaus-mcp-server/build/index.js"],
      "env": {
        "URLHAUS_AUTH_KEY": "your-auth-key-here"
      }
    }
  }
}
