Install Domain Availability — Bulk RDAP Status, Dates & Nameservers in Codex

What you need first

• Codex, installed.
• Nothing else: the server runs on its publisher's machines and Codex connects to it.

Steps

1. Run this in a terminal. It writes the server into ~/.codex/config.toml, which the Codex CLI, its IDE extension and the ChatGPT desktop app share.

codex mcp add domain-availability --url 'https://mcp.apify.com/?tools=hermeskd/domain-availability'

2. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of domain-availability.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Codex asks.
