Domains for agents.
Your agent registers, renews and points domains through an API, a CLI and an MCP server. Nothing here is bought or changed in a browser.
Paste it into Claude Code, Codex, Cursor or your own agent. It installs the CLI, signs you in and registers the MCP server.

Set up whydot (https://whydot.com) for me. whydot is an agent-native domain registrar: it has an HTTP API at https://api.whydot.com/v1, a CLI and an MCP server. 1. Install the CLI: curl -fsSL https://whydot.com/install.sh | sh 2. Sign in: whydot login --email me@acme.com It emails a 6-digit code; ask me for the code and type it in. The CLI stores the API key itself - never ask me to paste a key, and never print one. 3. Register the MCP server with your own harness: whydot mcp install 4. Read back what we already hold: whydot domains list --json Done when `whydot whoami` prints the account slug and `whydot domains list --json` returns without an auth error. Then tell me how many domains are in the account and the earliest expiry date.One contract, three surfaces
API
The product itself. Versioned at /v1, described by its own OpenAPI document, with an idempotency key on every call that spends money.
POST /v1/domainsCLI
A thin client over the API. Sign-in is an email code typed in the terminal; no browser is involved at any point.
whydot domains listMCP
The same operations as tools your agent calls directly. Nothing exists in one surface and not the others.
whydot_list_domainsWhat it does
- Availability checks and price quotes per TLD
- Registration, renewal and transfer, billed per domain
- Auto-renew on by default, with our own reminders sent early
- DNS records on a managed zone
- Cost and price shown side by side on every charge
- Scoped API keys, read-only ones included
- Not yet: a premium marketplace. Buying and selling existing names is being built. It will appear here when it works.
- Not yet: branded registrar mail. You are the registrant of record, so ICANN and registrar mail reaches you directly from Amazon Registrar.
- Never: buying or editing from this website. The console is read-only. Every change goes through the API, the CLI or the MCP server.
