安全提示

MCP 服务会接收对话中的工具调用请求，并可能执行外部操作。启用前请先了解该服务能做什么，并只授予它所需的权限。

注册中心已验证此服务的命名空间属于 cheapest.domains，且该域名同时运行其端点。这可以确认发布者，但并不代表该服务的工具是安全的。

SourceWeft 的检查只涵盖条目是否完整、端点是否响应；不审查服务器的代码，也不审查其工具的行为。

概览

AI 生成的概览

跨注册商比较域名注册与续费价格，并查询精确域名的可用性，帮助助手调研可负担的域名。

可以做什么: 按后缀搜索并比较各注册商价格，默认按年度续费排序，并附来源时间与过期标记
查看注册商覆盖范围、价格历史，以及单个后缀的注册加续费成本估算
查询单个精确域名的可用性，或一次查询一个名称在最多 20 个后缀下的情况，含溢价信息与查询尝试记录
查询域名在 Cloudflare Radar 的 DNS 热度排名，并获取命名标准说明
生成经验证的注册商搜索链接，并用缓存证据比较最多 10 个候选名称
适用场景: 适合在挑选域名时更看重长期续费成本而非首年价格，或在别处购买前确认某些名称是否已被注册。也适合并排比较多个候选名称与后缀。
运行要求: 远程 Streamable HTTP 端点，无需认证、账号或 API 密钥。AI 客户端需要网络访问；README 说明同一服务也可通过公开 REST API 使用。

安装前请注意

精确域名查询会把域名发送给该服务及其查询提供方，查询 URL 可能出现在托管日志中。可用性结果有时效性且不会保留域名；工具无法购买、注册、转移或续费域名。覆盖范围是部分选定注册商而非整个市场，价格、溢价状态与最短期限可能过期或未确认。Radar 热度数据适用单独的 CC BY-NC 4.0 许可。

README

Cheapest Domains integrations

Find domain names you can afford to keep. These integrations give an AI assistant domain-research instructions and access to the public Cheapest Domains service, focused on the real cost of keeping a domain: its annual renewal price. Compare renewals first, with initial registration prices shown separately, supported multi-year estimates, exact-name availability and registrar destinations. Your assistant generates the name ideas; Cheapest Domains supplies the evidence. Purchases happen at the registrar.

This repository contains the installable integrations for Codex, Claude Code, Cursor and other Agent Skills/MCP clients. It includes no application/server implementation, installation hooks, credentials or local service. Cheapest Domains requires no account or API key; your AI client has its own access requirements.

Install the plugin

Choose the commands for your client. The plugin includes both the skill and its remote MCP connection, so skip a duplicate standalone connection.

# Codexcodex plugin marketplace add igalil/cheapest-domains-integrationscodex plugin add cheapest-domains@cheapest-domains
# Claude Codeclaude plugin marketplace add igalil/cheapest-domains-integrationsclaude plugin install cheapest-domains@cheapest-domains

# Codexcodex plugin marketplace add igalil/cheapest-domains-integrationscodex plugin add cheapest-domains@cheapest-domains
# Claude Codeclaude plugin marketplace add igalil/cheapest-domains-integrationsclaude plugin install cheapest-domains@cheapest-domains

Start a new Codex chat or reload Claude's plugins after installation. In Claude Code, invoke /cheapest-domains:domain-research. In Codex, ask to use the Cheapest Domains domain-research skill.

Install only the skill

This installs instructions, not an MCP connection. Use a connected MCP server or the skill's public HTTPS fallback when your client permits network access. Skills.sh directory discovery depends on installation telemetry; this repository is not proof of a listing in any third-party directory.

Connect only MCP

Use https://cheapest.domains/mcp, Streamable HTTP, with no authentication. For Cursor or another compatible client, see the setup instructions. The same service is available through the public REST API.

Try it

Use Cheapest Domains to show three extensions with annual renewals at or below USD 15. Include source times and a comparison link. Do not check exact names.

For name suggestions, tell the assistant about your project, preferred style and budget. It checks suggestions by default within service limits. Ask for unchecked brainstorming if you do not want proposed names sent to checking providers.

Scope and privacy

The service compares selected registrars, not the whole market. Preserve original source dates, stale/partial coverage, premium uncertainty and minimum terms. Availability is temporary and does not reserve a name. The tools cannot buy, register, transfer or renew domains. Radar popularity is DNS activity, not SEO competition or availability, and retains its separate CC BY-NC 4.0 license.

The skill keeps project briefs local and sends only the query inputs needed for research. Exact-name checks can send a domain to the service and its checking providers. Query URLs may appear in hosting logs. See the privacy policy and terms.

工具

search_prices

Compare renewal prices

Compare standard prices, including explicitly labeled Cloudflare samples. Find affordable domain extensions and registrar offers, sorted by annual renewal by default. Saved offers stay listed after a failed refresh, with stale flags and source timestamps for stating their age. Returns prices, citation links, timestamps, coverage, and pagination. Does not check exact-name availability.

get_tld_prices

Compare prices for an extension

Compare all covered registrars for one extension. Returns source failures, quote timestamps and minimum terms; availability is not checked.

get_registrars

Get registrar coverage

Get connected registrar coverage, timestamps, fresh counts, failures, and registrars not compared.

无需输入参数。

estimate_cost

Estimate domain costs

Estimate new registration plus subsequent renewals for one TLD at a registrar. Returns null for unknown multi-year term totals. Not a transfer or existing-domain renewal quote.

输入参数tld必填nameyears必填registrar必填

get_registrar_link

Get a registrar search link

Construct a verified registrar search destination for a proposed name and extension. Does not navigate, check availability, or purchase. NameBright and AWS Route 53 use an explicit copy/paste fallback.

输入参数tld必填name必填registrar必填

get_naming_guidance

Get domain naming guidance

Return domain naming criteria, renewal-price comparison guidance and availability-status definitions. This static reference does not generate names or check availability.

无需输入参数。

check_availability

Check domain availability

Check one exact domain. Cloudflare answers first; configured fallbacks, then an optional selected registrar, run only for missing facts; a taken name ends the chain. Returns separate availability and nullable premium facts, provider attempts and check times; null premium is unconfirmed, not standard tier. Recheck after expiresAt (5 min; up to 30 days if taken). No prices, purchase or reservation.

输入参数tld必填name必填freshregistrar

get_domain_popularity

Get domain DNS popularity

Look up one exact domain in Cloudflare Radar’s global DNS popularity ranking. Returns an exact top-100 rank or a broader popularity group, categories, locations, data dates, and CC BY-NC 4.0 attribution. Not Google SEO difficulty, name competition, or availability. Missing data does not indicate zero competition.

输入参数tld必填name必填

check_availability_batch

Check a name across extensions

Check one name across up to 20 extensions, reusing shared evidence. Enrichment stops once availability is known, so premium can remain null. Partial failures keep the answers received plus retry guidance, without automatic retries. cachedOnly makes no provider calls. No selected-registrar fallback, fresh mode, prices or purchases.

输入参数name必填tlds必填cachedOnly

open_name_finder

Find project domain names

Open the naming form in a compatible host, or return its text workflow. Collect seed names, an optional project brief, count and annual renewal budget; the current assistant generates ideas and checks them with the research tools. Opening performs no generation or registrar checks. Does not connect subscriptions or require a model API key.

无需输入参数。

get_price_history

Get price history for an extension

Return how each covered registrar's renewal or registration price for one extension changed over time: price periods with the date each price was first seen, when the previous price was last seen, and whether it came from our scheduled refreshes or the registrar's own price page archived by the Internet Archive. A first record may be older than its date. Availability is not checked.

输入参数tld必填priceformatregistrar

compare_domain_names

Compare suggested domain names

After checking exact names with the availability tools, compare up to 10 candidates using saved renewal-first prices and fresh cached evidence. No new availability requests; cache misses are Not confirmed. Returns standard reference offers, premium facts, dates and links. The assistant explains project fit. Split larger lists into bounded groups. Does not generate names.
