常见问题

Just Domain. 安全吗？

它在 3 项适用的基础检查中通过了 2 项。我们没有阅读代码。在添加密钥或令牌之前，请先看看这个服务器要求哪些权限，并使用只具备所需权限的密钥。

它需要哪些密钥或代码？

注册中心没有列出必需的密钥，不过有些服务器会在首次使用时要求你登录。

它在我的电脑上运行还是在云端？

它在作者的云端运行。通过互联网连接，无需安装，但你发送的内容会经过作者的服务器。

它还在维护吗？

GitHub 仓库最后更新于–，最新版本（0.8.4）于8天前进入注册中心。

哪些应用可以使用它？

支持 MCP 的应用，例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接，所以接受远程 MCP 服务器的应用也可以使用，例如开启开发者模式的 ChatGPT。

有什么可以替代它？

同一分类中有：Spec Driven Development, Remote Desktop Commander, Statuser

Just Domain - MCP Server

Check a domain name, both prices and whether it can transfer in, and check the name against trademark registers. You register it on justdomain.ai.

Ask your AI assistant whether a name is free and what it costs, and it hands back a link to register it on justdomain.ai without leaving the conversation. Ask it about a domain you already own at another registrar and it reports what would block a transfer, whether your DNS survives the move, and the full-term transfer price. Ask it whether a name is already a trademark and it checks the registers Open Trademarks (https://opentrademarks.org) has read, naming each register and its read date. Every tool is read-only: nothing is bought, filed, charged or changed 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)
Auth: none. Every tool is read-only and unauthenticated.

Connecting

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

Then ask your assistant to check a domain.

Tools

Tool	What it does
`search_domains`	Check one or more domain names: returns availability, the registration price, the 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, two years on `.ai`, whose registry mandates a two-year term. Read-only; no order or payment in chat.
`check_domain_transfer`	Precheck ONE domain you already own at another registrar: what would block a transfer, who sponsors it today, whether its DNS keeps working through the move, and the full-term transfer price. Answered from the registry's own public RDAP record plus our registrar's price list, so it reads no account and no database. An empty `blockers` list is the only thing that means ready.
`check_trademark`	Check ONE proposed name against the trademark registers Open Trademarks covers (US, EU and Israel), answered by Open Trademarks. A register with no read date in the answer was not checked. Returns a `verdict` (`exact_live_mark`, `similar_live_marks`, `no_live_match`, or `not_checked`, which is no verdict), the conflicting marks, and each register's read date. Optional `goods`, `classes` (Nice 1 to 45) and `registers` narrow it. A register search is not legal advice, and no answer clears a name.

The same transfer facts are published over plain HTTP for agents with no MCP client:

GET https://mcp.justdomain.ai/api/transfer/precheck?domain=example.com

Unauthenticated, read-only, no key. It is served by the MCP host above, not by the justdomain.ai website.

What these tools will not do

No purchase, no payment, no filing and no order is created by any tool. A registration is completed by a person in a browser on justdomain.ai.
Moving a domain in is self-service in a browser: the owner checks it and pays at https://justdomain.ai/transfer, pasting the authorization code there. check_domain_transfer reports whether a domain is eligible and what one full term costs, and hands back a transfer_url that opens that page for the domain.
No trademark tool clears a name. Never tell a user a name is clear unless it was checked in the same conversation and every register in the answer was read today or yesterday.
No authorization (EPP) code is ever returned, accepted or hinted at, and there is no agent path to unlocking a domain or to having a code issued. Moving a domain out is self-service, and self-service there means a human owner signed in on justdomain.ai in a browser: they switch the transfer lock off and get the code from their own account. An auth code is a bearer credential for the domain, and a chat transcript is not a place to put one.
Premium names are reported but cannot be registered or transferred through Just Domain yet.

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

This repo also ships a [SKILL.md](https://learn.chatgpt.com/docs/build-skills)-format Agent Skill for Just Domain: a small package that teaches an agent *when* and *how* to use the three tools, and where to stop. 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 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, anyone wondering whether the domain they already own could move somewhere better or whether a name is already a trademark, and AI agents that need a real availability lookup with a clean handoff to registration.
