Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "onlydns": {
      "command": "npx",
      "args": [
        "-y",
        "@onlydns/mcp"
      ],

        "ONLYDNS_API_BASE_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add onlydns --env ONLYDNS_API_TOKEN=your-value --env ONLYDNS_API_BASE_URL=your-value -- npx -y @onlydns/mcp

Fill in the empty values before running it.

Open in Cursor

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions

Is OnlyDNS MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ONLYDNS_API_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.6) reached the registry 7 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

OnlyDNS MCP Server (`@onlydns/mcp`)

Official Model Context Protocol (MCP) server for OnlyDNS enabling AI agents (Claude Desktop, Cursor, Devin, LangChain) to inspect and manage DNS zones, records, 1-click DNSSEC, and TSIG keys directly. Learn more on the AI Agent Infrastructure solution page.

npm install -g @onlydns/mcp

*Or run instantly:* npx -y @onlydns/mcp

Authentication Environment Variable: ONLYDNS_API_TOKEN (see Configuration).

Features

🌐 Domain Management: List all managed domains and create new DNS zones.
📝 DNS Record Operations:
list_records: Query DNS records with optional filtering by type (A, AAAA, CNAME, MX, TXT, SRV, CAA, etc.) or hostname.
add_record: Create new records or append values to existing record sets with automatic domain normalization.
update_record: Modify existing DNS records and update TTLs.
delete_record: Delete specific record values or entire record sets.
set_records: Batch replace full zone record sets.
🔐 DNSSEC Management: Inspect DNSSEC status, fetch DS/DNSKEY records, enable, and disable DNSSEC signing.
🔑 TSIG Keys: Generate and manage TSIG keys for secondary DNS zone transfers (AXFR) and RFC 2136 dynamic updates.

Installation & Quick Start

1. One-Click Desktop Installation (MCPB Bundle)

Download onlydns-mcp.mcpb directly from the GitHub Releases page. Compatible desktop clients (such as Claude Desktop) allow one-click installation and configure your ONLYDNS_API_TOKEN through a secure settings dialog.

2. Using `npx` (No installation needed)

You can run the server directly using npx:

export ONLYDNS_API_TOKEN="your_onlydns_api_token"

npx -y @onlydns/mcp

3. Global Installation

npm install -g @onlydns/mcp

Configuration

The server requires an OnlyDNS API Bearer Token.

Environment Variables

Variable	Description	Default
`ONLYDNS_API_TOKEN`	Your OnlyDNS API Bearer Token (Required)	-
