安全提示

MCP 服務會接收對話中的工具呼叫請求，並可能執行外部操作。啟用前請先了解該服務能做什麼，並只授予它所需的權限。

註冊中心已驗證此服務的命名空間屬於 cheapest.domains，且該網域同時執行其端點。這可以確認發布者，但並不代表該服務的工具是安全的。

SourceWeft 的檢查只涵蓋條目是否完整、端點是否回應；不審查伺服器的程式碼，也不審查其工具的行為。

概覽

AI 產生的概覽

跨註冊商比較網域註冊與續約價格，並查詢精確網域的可用性，協助助理研究可負擔的網域名稱。

可以做什麼: 依副檔名搜尋並比較各註冊商價格，預設依年度續約價排序，並附上來源時間與過期標記
檢視註冊商涵蓋範圍、價格歷史，以及單一副檔名的註冊加續約成本估算
查詢單一精確網域的可用性，或一次查詢一個名稱在最多 20 個副檔名下的狀況，含溢價資訊與查詢嘗試紀錄
查詢網域在 Cloudflare Radar 的 DNS 熱門度排名，並取得命名準則說明
產生經驗證的註冊商搜尋連結，並用快取證據比較最多 10 個候選名稱
適用情境: 適合在挑選網域時更重視長期續約成本而非首年價格，或在別處購買前確認某些名稱是否已被註冊。也適合並排比較多個候選名稱與副檔名。
執行需求: 遠端 Streamable HTTP 端點，無需驗證、帳號或 API 金鑰。AI 用戶端需要網路存取；README 說明同一服務也可透過公開 REST API 使用。

安裝前請注意

精確網域查詢會把網域傳送給該服務及其查詢提供者，查詢 URL 可能出現在主機日誌中。可用性結果有時效性且不會保留網域；工具無法購買、註冊、移轉或續約網域。涵蓋範圍是部分選定註冊商而非整個市場，價格、溢價狀態與最短期限可能過期或未確認。Radar 熱門度資料適用獨立的 CC BY-NC 4.0 授權。

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_registrars

Get registrar coverage

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

無需輸入參數。

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.

輸入參數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.

輸入參數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.

無需輸入參數。

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.

輸入參數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.

輸入參數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.

輸入參數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.

無需輸入參數。

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.

輸入參數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.
