概览

AI 生成的概览

跨 145+ 家注册商和 1,100+ 个顶级域名比较域名价格，查找优惠码并查询域名是否可注册。

可以做什么
  • 按后缀找出首年注册、续费、转移和三年总价最便宜的注册商
  • 列出某个后缀下各注册商的注册、续费和转移价格，并给出均价与中位数
  • 最多并排比较 20 个后缀的注册商价格
  • 查看某个后缀各注册商的注册与续费价格历史
  • 按折扣从大到小列出当前有效的注册商优惠码
  • 实时查询完整域名的可注册状态，并列出已收录注册商及其 WHOIS 隐私信息
适用场景
适合在决定去哪里注册、续费或转移域名时使用，也适合比较多个后缀的多年成本，或在购买前确认某个域名是否已被占用。
运行要求
需要 TLDers API 密钥：连接托管端点时以 Authorization 请求头中的 bearer 令牌发送，运行本地服务器时通过 TLDERS_API_KEY 环境变量提供。本地方式需要 Node.js 18+，并需能访问托管端点。免费方案每月 100 次请求，付费方案额度更高。
安装前请注意
API 密钥属于凭据：通过 URL 查询参数传递的密钥应视同密码，一旦泄露应在账户中吊销并重新生成。所有工具均为只读，不会购买或注册域名，但价格与可注册状态来自第三方服务，注册局无法访问时可用性结果可能为空。

安装

在 SourceWeft 中

  1. 打开 控制台中的 TLDers Domain Prices，将其添加到工作区。
  2. 连接 Authorization token 凭据。它们会被私密存储，绝不会在公开页面上展示。
  3. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/com.tlders%2Fdomain-prices/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

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?"
