Documentation

Just Domain — MCP Server

Search domain availability and pricing, straight from chat — then open a link to register.

Ask your AI assistant whether a domain is free and what it costs. The Just Domain MCP server checks availability and registration + renewal pricing and hands back a link to register the name on justdomain.ai — without leaving the conversation. It's read-only: nothing is bought or charged in the chat.

Website: https://justdomain.ai
MCP endpoint: https://mcp.justdomain.ai/
Registry name: ai.justdomain/just-domain
Transport: Streamable HTTP (remote — nothing to install)

Connecting

{
  "mcpServers": {
    "just-domain": {
      "type": "streamable-http",
      "url": "https://mcp.justdomain.ai/"
    }
  }
}

Then ask your assistant to check a domain. It returns availability, pricing, and a registration link.

Tools

Tool	What it does
`search_domains`	Check one or more domain names: returns availability, registration price, renewal price, and — for available names — a URL to open and register on justdomain.ai. Both prices are totals for one full registration term of that ending, not per-year rates: one year on most endings, but two years on `.ai`, whose registry mandates a two-year term. Read-only; no order or payment in chat.

Agent Skill (ChatGPT / Codex / any SKILL.md runtime)

This repo also ships a SKILL.md-format Agent Skill for Just Domain — a small package that teaches an agent when and how to use the search_domains tool (check availability + pricing, then hand the user a link to register — never buying in the chat). It lives at skills/just-domain/.

Install (Codex / any GitHub-tree installer): point the skill installer at the GitHub tree URL —

https://github.com/just-done/just-domain-mcp/tree/main/skills/just-domain

Manual install: copy the skills/just-domain/ folder into your runtime's skills directory — $CODEX_HOME/skills/ (or ~/.codex/skills/) for Codex, ~/.claude/skills/ for Claude.

The same package is also served for discovery on the MCP host, for other runtimes and /.well-known scanners:

Index: https://mcp.justdomain.ai/.well-known/agent-skills/index.json
Skill: https://mcp.justdomain.ai/.well-known/agent-skills/just-domain/SKILL.md

The skill still needs the MCP server connected (see Connecting above) — it declares that dependency in agents/openai.yaml.

Who it's for

Anyone naming a project, business, or idea in a chat — and AI agents that need a real domain-availability lookup with a clean handoff to registration.
