Dns MCP Server

DNS lookups, reverse DNS, WHOIS, and domain checks from your AI assistant. No API keys, no config. Powered by Node.js built-in DNS. Its 5 documented tools cluster into dns, reverse, resolve, check. It runs locally over stdio via the published package.

People who work with dns, domain and network and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Dns

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add ofershap-mcp-server-dns -- npx -y mcp-server-dns

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ofershap-mcp-server-dns": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-dns"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package mcp-server-dns - unscoped; check the name against the project README before installing

registry namespace io.github.ofershap is GitHub-verified and matches the repo owner

03 · What Dns can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can resolve A, AAAA, MX, TXT, NS, CNAME in one call, and get nameserver (NS) records for a domain.
