DNS management
for AI assistants

Setup

Three steps, then forget about it

1

Add the MCP server

Paste the server URL into claude.ai as a remote MCP integration. You'll be redirected to a login page.

2

Enter your Namecheap credentials

Your username and API key. They're AES-256-GCM encrypted into your OAuth token. The server stores nothing.

3

Whitelist the server IP

Your first tool call tells you exactly which IP to whitelist, with a direct link. One click, done forever.

Security

Your credentials, your control

⚿

Stateless tokens

Credentials are encrypted into the OAuth token itself. The server has no database, no storage, no state.

◆

AES-256-GCM

Industry-standard authenticated encryption. Tokens can't be tampered with or forged.

❐

PKCE verification

Authorization codes use S256 code challenge to prevent interception attacks.

⊙

Safe DNS writes

Every write fetches all records first, modifies, then writes back. No accidental deletions.
