@domainkits/mcp

MCP server for the DomainKits domain data API.

This is the official MCP server for the DomainKits API, published and maintained by the DomainKits team. DomainKits is built and operated by Lyalpha GmbH, with domain data and infrastructure provided by ABTdomain, our domain intelligence and data aggregation platform. This repository is hosted under the ABTdomain GitHub organisation. Learn more about the relationship at domainkits.com/about.

DomainKits is one API with a shared key across every surface. This package exposes the full DomainKits tool set to any MCP client: expiring domains, newly registered domains, DNS, WHOIS, reverse nameserver lookups, typosquat detection, TLD trends and more.

Works without an API key on a guest quota, so you can try it before signing up.

Install

No install step. Point your MCP client at the package and npx fetches it on first run.

Claude Desktop: add to claude_desktop_config.json:

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

Cursor: add to .cursor/mcp.json in your project, or the global equivalent. Same shape as above.

Any MCP client that speaks stdio works with the same config.

Credentials

No key required to start. Without one you run on a guest quota, enough to see what the data looks like. A free account raises the limits and unlocks filters; paid tiers raise them further. Current tiers and limits: domainkits.com/pricing. The usage tool reports the live quota for your own account at any time.

To use a key, add it to the env block:

{
  "mcpServers": {
    "domainkits": {
      "command": "npx",
      "args": ["-y", "@domainkits/mcp"],
      "env": {
        "DOMAINKITS_API_KEY": "dk_xxxxxxxxxxxxxxxx"
      }
    }
  }
}

Keys come from domainkits.com and work across every DomainKits surface: this MCP server, the REST API, and the n8n node. The key is never written to disk by this package.

monitor	Manage domain monitoring tasks across WHOIS, DNS and page content
preferences	Manage saved preferences and the memory switch
strategy	Store your own strategy text and its run results

Each tool ships its own input and output schema, so the client knows what arguments are valid before calling. The tool list is served live by the endpoint, so your client always sees the current set.

Stateful tools and what they store

Search and lookup tools are stateless: nothing you ask is retained. Three tools do store data across sessions, by design:

Tool	What it stores
monitor	The domains you watch and the results of each check
preferences	Your saved preferences and the memory switch
strategy	Strategy text you wrote, run timestamps and the most recent result

Storage is opt-in. Memory is off by default and must be enabled through preferences before monitor or strategy will accept anything. Stored data is encrypted at rest in isolated per-user directories, persists across MCP clients under the same account, and can be deleted in full at any time with preferences action: delete.

No tool returns domain registrant personal data. registrar returns ICANN-published registrar business contacts.

What this package does

It is a stdio transport for the hosted DomainKits MCP endpoint. Tool definitions, filtering and rate limiting all live server-side, so the tool list stays current without republishing this package.

If your client supports remote MCP over HTTP, you can skip this package and connect to the endpoint directly, see the API reference.

Configuration

Variable	Default	Purpose
DOMAINKITS_API_KEY	(none)	Optional. Without it you run as a guest.
DOMAINKITS_MCP_URL	https://api.domainkits.com/v1/mcp	Override the endpoint.
