DNSDumpster MCP Server

MCP Server for DNSDumpster Service

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "anhhung04-mcp-dnsdumpster": {
      "command": "uvx",
      "args": [
        "mcp-dnsdumpster"
      ],

You can leverage the DNSDumpster MCP server to perform DNS reconnaissance through natural language prompts. It queries the DNSDumpster API to fetch DNS records and related insights for domains, enabling AI assistants to provide detailed, structured DNS information.

How to use

Interact with an MCP client to send natural language requests that resolve into DNS queries. You can ask for subdomains, DNS records, and infrastructure details, and the server will fetch supported data from DNSDumpster and present it back in an organized way.

How to install

Prerequisites: Python 3.10+, a working Internet connection, and an MCP client capable of consuming MCP HTTP or STDIO endpoints.

Install the DNSDumpster MCP server from its package source with the runtime you prefer.

# Option 1: Install and run via the MCP runner (recommended)
uvx mcp-dnsdumpster

# Option 2: Install from source and run directly
# Install dependencies
uv pip install -e .

# Run the server directly (from source)
uv run server.py
