Overview

mcp-dnsdumpster is an MCP server that interacts with the DNSDumpster API, allowing AI assistants to perform detailed DNS reconnaissance through natural language requests.

To use mcp-dnsdumpster, install the package via PyPI or from source, set your API key, and run the server. You can then query DNS records using natural language prompts.

Query domain DNS records through AI assistants - Retrieve detailed information about A, CNAME, MX, TXT, NS records, and Banner information - Support for pagination and domain map generation (Plus accounts) - Rate limiting and caching

Performing DNS reconnaissance for cybersecurity assessments
Analyzing domain structures for research purposes
Automating DNS queries in AI-driven applications

      ]
    }
  }
}
