What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Other
You need to fill in: LWS_LOGIN, LWS_API_KEY, LWS_TEST_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: LWS_LOGIN, LWS_API_KEY, LWS_READ_ONLY, LWS_ENABLE_PURCHASES, LWS_TEST_MODE, LWS_TEST_API_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

PyPIPython’s uv installed (for the uvx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

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": {
    "lws": {
      "command": "uvx",
      "args": [

        "LWS_TEST_MODE": "your-value",
        "LWS_TEST_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add lws --env LWS_LOGIN=your-value --env LWS_API_KEY=your-value --env LWS_READ_ONLY=your-value --env LWS_ENABLE_PURCHASES=your-value --env LWS_TEST_MODE=your-value --env LWS_TEST_API_KEY=your-value -- uvx lws-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "lws": {
      "type": "stdio",
      "command": "uvx",

Common questions

Is LWS 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: LWS_LOGIN, LWS_API_KEY, LWS_TEST_API_KEY

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 (0.2.1) reached the registry 22 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

lws-mcp

English · Français

An MCP server for the LWS Client API. Manage your domains, DNS zones, hosting and account from Claude, Cursor or any MCP client:

*"Add the CNAME records Stripe gave me to example.fr, then tell me when they are live."*

It covers the whole LWS Client API (29 endpoints), plus a propagation check that compares your LWS zone, its nameservers and three public resolvers.

Community project, not affiliated with or endorsed by LWS.

Tools

Area	Tools
DNS	`get_dns_zone` · `add_dns_record` · `update_dns_record` · `delete_dns_record` · `check_dns_propagation`
Domains	`get_domain` · `check_domain_availability` · `list_tlds` · `update_nameservers` · `set_transfer_protection` · `request_transfer_authcode` · `create_domain_redirect` · `delete_domain_redirect`
Hosting	`list_hostings` · `get_hosting` · `list_hosting_prices` · `get_renewal_prices` · `set_auto_renew` · `buy_hosting`¹ · `renew_hosting`¹
Account	`get_account_balance` · `get_purchase_history` · `list_contacts` · `get_contact` · `create_contact` · `update_contact` · `add_test_credit_to_contact`² · `add_test_credit_to_account`²
Requests	`list_requests` · `list_pending_requests`

¹ Paid: off unless LWS_ENABLE_PURCHASES=true. ² Only in test mode.

DNS record names can be written in full (_dmarc.example.fr): they are shortened to what the LWS zone expects (_dmarc, @).

Safety

An assistant with access to your DNS can take a site or a mailbox down, and one with access to purchases can spend money. So:

Purchases are off by default. buy_hosting and renew_hosting only exist when LWS_ENABLE_PURCHASES=true.
Read-only mode. LWS_READ_ONLY=true removes every tool that changes something.
Hints for your client. Every tool declares whether it reads, writes or destroys (tool annotations), so clients can ask before running it.
Test environment. LWS_TEST_MODE=true sends every request to the LWS sandbox.
Your key stays local. It goes only to api.lws.net, and is never logged or returned to the model.

Requirements

An LWS account and its API key: LWS Panel → your account number (LWS-XXXXXX, top right) → Api LWS → Clé API en mode PRODUCTION → *voir*. LWS guide.
The public IP address of the machine running the server, allowed on the same Api LWS page. Otherwise every call fails with bad source .
uv (it fetches Python and the server for you).

Installation

Every client runs the same command, uvx lws-mcp, with LWS_LOGIN and LWS_API_KEY in its environment (see Configuration for the optional settings).

The buttons leave LWS_LOGIN and LWS_API_KEY empty: fill them in after installing.

Good to know

Deferred actions. Nameserver changes, transfer protection, auth codes, purchases and renewals are processed in the background. Follow them with list_pending_requests.
Propagation. A DNS change can take from minutes to a few hours to be seen everywhere: each resolver keeps the old answer until its TTL runs out. check_dns_propagation compares what is saved in the LWS zone, what the domain's nameservers answer (no cache) and what Cloudflare, Google and Quad9 answer, then says how long a stale answer can last. Some networks block direct DNS queries to nameservers; the resolvers are asked over HTTPS, so that part always works.
Record ids change. LWS replaces a record under a new id when it is updated. add_dns_record and update_dns_record return the current id.
Rate limit. LWS refuses bursts of requests (about fifteen in a row) with Invalid input (rate limit): wait a minute and retry.
Allowed TTLs. 900, 1800, 3600, 7200, 21600, 43200 or 86400 seconds.

Development

git clone https://github.com/NKSTUD/lws-mcp && cd lws-mcp

uv sync uv run pytest uv run ruff check . && uv run ruff format --check .

Try it against your account with the MCP Inspector, credentials in a local .env (see .env.example):
