Connect your assistant

codex mcp add cheapest-domains --url https://cheapest.domains/mcpRun this command in your terminal, then open Claude Code and use /mcp to check the connection. If you already installed our plugin, use that connection.
claude mcp add --transport http --scope user cheapest-domains https://cheapest.domains/mcpIn a client that supports custom remote MCP servers, add this URL with Streamable HTTP transport and no authentication. Connection options depend on your app and account.
https://cheapest.domains/mcpChatGPT access depends on the plugins or custom connections available in your account. This page does not install a ChatGPT integration. A browser that supports WebMCP can discover our tools while visiting the site.

Try one small comparison
Paste this into your connected assistant. It reads saved prices and does not send a proposed domain name.
Use Cheapest Domains search_prices to show three extensions with annual renewals at or below USD 15. Show the registrar, registration and renewal prices, source timestamp, and comparison link. Say if coverage is partial. Do not check domain availability. If the tool is unavailable, say so instead of inventing results.Look for a tool result with source dates and links. A copied prompt does not confirm a connection. If tools are unavailable, use the REST API in a client with HTTP access or compare on the website. If the service asks you to wait, respect its retry guidance.
Bring your project and a budget
Your assistant creates the ideas. Cheapest Domains supplies price comparisons and separate checks for your chosen names.
Find names for your project
Suggest eight memorable domain names for my project using the context we have discussed. Use Cheapest Domains to shortlist extensions with renewals at or below USD 15 per year. Show standard registration and renewal prices, supported five-year estimates, source dates, and comparison links. Keep the names unchecked until I choose up to three finalists for availability and premium checks. If you cannot access the tools, say so.Compare an extension
Use Cheapest Domains to compare fresh .com offers among the registrars it covers. Rank by renewal price and show registration, renewal, supported five-year estimates, source dates, and comparison links. Preserve sample, tax, conversion, and minimum-term qualifications. These are standard extension prices; do not check an exact name.What the results mean
Prices cover standard, non-premium domains among the registrars we compare. Coverage varies by extension. Saved prices normally refresh after six hours; check the source date. Multi-year totals are estimates, and future rates can change.
Check up to three finalists at a time. Availability and premium status are separate facts; an unknown answer stays unconfirmed. Checks expire after one minute and do not reserve a domain. Exact premium prices and final terms are confirmed at the registrar.
Exact-name checks send the domain to the checking providers. Keep confidential project details in your conversation. Read our privacy explanation before sharing a name.
