Overview
What is ExternalAttacker MCP Server?
ExternalAttacker MCP Server is a model context protocol integration that brings automated external attack surface management and reconnaissance capabilities through a natural language interface. It allows users to run scans, analyze infrastructure, and discover vulnerabilities by issuing plain-English queries to an AI assistant.
How to use ExternalAttacker MCP Server?
Clone the repository, install the Python dependencies, install the required Go tools (subfinder, naabu, httpx, cdncheck, tlsx, ffuf, gobuster, dnsx), then run ExternalAttacker-App.py and access the local web interface (default port 6991). Finally, configure the MCP server in your MCP client by adding the command python <path>/ExternalAttacker-MCP.py to the mcpServers section.
