Cheapest Domains MCP server

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.

# Codex
codex plugin marketplace add igalil/cheapest-domains-integrations
codex plugin add cheapest-domains@cheapest-domains

# Claude Code
claude plugin marketplace add igalil/cheapest-domains-integrations
claude 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

npx skills add igalil/cheapest-domains-integrations --skill domain-research

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.
