概覽

AI 產生的概覽

跨 145+ 家註冊商與 1,100+ 個頂級網域比較網域價格、尋找優惠碼，並查詢網域是否可註冊。

可以做什麼
  • 依副檔名找出首年註冊、續約、移轉與三年總價最便宜的註冊商
  • 列出某個副檔名下各註冊商的註冊、續約與移轉價格，並附平均與中位數
  • 最多並排比較 20 個副檔名的註冊商價格
  • 查看某個副檔名各註冊商的註冊與續約價格歷史
  • 依折扣由大到小列出目前有效的註冊商優惠碼
  • 即時查詢完整網域的可註冊狀態，並列出已收錄註冊商及其 WHOIS 隱私資訊
適用情境
適合在決定到哪裡註冊、續約或移轉網域時使用，也適合比較多個副檔名的多年成本，或在購買前確認某個網域是否已被使用。
執行需求
需要 TLDers API 金鑰：連線託管端點時以 Authorization 標頭中的 bearer 權杖傳送，執行本機伺服器時透過 TLDERS_API_KEY 環境變數提供。本機方式需要 Node.js 18+，並需能連線託管端點。免費方案每月 100 次請求，付費方案額度較高。
安裝前請注意
API 金鑰屬於憑證：以 URL 查詢參數傳送的金鑰應視同密碼，一旦外洩應在帳戶中撤銷並重新產生。所有工具皆為唯讀，不會購買或註冊網域，但價格與可註冊狀態來自第三方服務，註冊局無法連線時可用性結果可能為空。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 TLDers Domain Prices，將其新增到工作區。
  2. 連接 Authorization token 憑證。它們會被私密儲存，絕不會在公開頁面上展示。
  3. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/com.tlders%2Fdomain-prices/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

README

TLDers Domain Prices — MCP server

[M8ven Score] [test] [npm]

Live domain prices from 145+ registrars and 1,100+ TLDs, as a remote Model Context Protocol server. Ask your AI assistant where a domain is cheapest to register, renew or transfer, compare extensions, find promo codes and check availability — with real, daily-updated prices from TLDers.

Use it two ways: connect to the hosted server at https://www.tlders.com/api/mcp, or run this repository's small local (stdio) server, which forwards each tool call to the hosted one with your key.

Connect

  1. Get a free API key at https://www.tlders.com/developers (no card needed).
  2. Add a remote MCP server (Streamable HTTP):
ClientSetting
Clients that support headers (Claude Code, Cursor, VS Code, MCP Inspector)URL https://www.tlders.com/api/mcp, header Authorization: Bearer tld_live_...
claude.ai custom connectors and other clients without header supportURL https://www.tlders.com/api/mcp?key=tld_live_...

Claude Code:

sh
claude mcp add --transport http tlders https://www.tlders.com/api/mcp \  --header "Authorization: Bearer tld_live_..."

Treat a URL with ?key= like a password. If it leaks, revoke the key from your TLDers account and create a new one.

Local (stdio) server

For Claude Desktop's config file and other clients that run local servers. Needs Node.js 18+.

json
{  "mcpServers": {    "tlders": {      "command": "npx",      "args": ["-y", "@tlders/mcp"],      "env": { "TLDERS_API_KEY": "tld_live_..." }    }  }}

To run the server from source instead of the published package (useful while changing it), clone this repo, run npm install, then use "command": "node", "args": ["/path/to/tlders-mcp/index.js"]. It reads the same TLDERS_API_KEY variable, and TLDERS_MCP_URL overrides the hosted endpoint.

Plugin install

This repo is also an Agent Plugins package (plugin.json + mcp.json) that connects to the hosted server. Once installed, add your key by passing it as the api_key argument or switching the server URL to https://www.tlders.com/api/mcp?key=tld_live_....

Tools

ToolWhat it does
find_cheapest_tldsCheapest registrar per extension for first-year registration, renewal, transfer and 3-year total
get_tld_pricesEvery registrar's register / renew / transfer price for one extension, cheapest first
compare_tldsCompare registrar prices across up to 20 extensions
get_tld_price_historyPer-registrar registration and renewal price history
list_promo_codesActive registrar promo codes, biggest discount first
check_domain_availabilityLive availability for a full domain name (RDAP, WHOIS fallback)
list_registrarsEvery tracked registrar with WHOIS-privacy info

Prices are USD per year. First-year prices are often promotions, so the renewal price is always included.

All tools are read-only. Each one is annotated readOnlyHint: true, destructiveHint: false and idempotentHint: true. Nothing is bought, registered or changed, so clients can run them without asking for confirmation.

Example prompts

  • "Where is a .com cheapest to register and to renew?"
  • "Compare .io, .ai and .dev prices over three years."
  • "Is my-startup.dev available, and which registrar should I buy it from?"
  • "Are there any promo codes for .xyz right now?"
