TLDers Domain Prices — Claude Code MCP server for domain costs

claude mcp add domain-prices -e TLDERS_API_KEY=<TLDERS_API_KEY> -- npx -y @tlders/mcpWhat TLDers Domain Prices does
This MCP server compares registrar prices for domain registration, renewal and transfer. It can compare up to 20 extensions, show price history, and list active promo codes. Availability checks use RDAP, with WHOIS as a fallback.
Prices are in USD per year. Since first-year rates often include promotions, renewal prices are shown too. The tools are read-only: they do not buy domains or change settings. Connecting requires a TLDers API key; running the local server requires Node.js 18+.
What it helps with
- find the cheapest registrar for a domain extension
- compare registration and renewal costs
- check whether a full domain name is available
- find an active registrar promo code
