Ask ChatGPT, Claude, or Grok for business name ideas and you get a confident list in seconds. Ask whether the .com is free and the answer is usually a guess. Many of the domains an assistant suggests were registered years ago, and you only find out after you have grown attached to a name.
The fix is not a better prompt. It is giving the assistant a tool that checks domains live, so it only calls a name available when you can actually register it.
Why AI assistants suggest domains that are already taken
A chat model learns language from a snapshot of text. It knows what names sound like good brands, but it has no view of the domain registry as it is today. When it says a domain looks available, it is predicting, not checking.
That gap matters most for the names you would want. Short, pronounceable, one-word .com names are exactly the ones that are most often registered. An assistant that cannot check will keep proposing them.
Some assistants can browse the web, but a search result is not a registry lookup. A parked page, a for-sale listing, and an unused registration can all look like "nothing is there" from a quick search.
What changes when the assistant can check domains
The Model Context Protocol (MCP) is an open standard that lets AI apps call outside tools on your behalf. A naming tool connected over MCP gives the assistant abilities it does not have on its own:
- Generate names with availability built in. The assistant sends your brief to a name generator that checks each domain before returning it, so the list it shows you is already filtered to names you can register.
- Check the names it thinks up. When the assistant brainstorms names on its own, it can check each domain live before showing it to you, plus the price when a domain is listed for sale.
- Screen for trademarks. Run a shortlist against USPTO and EUIPO records before anyone falls in love with a name.
- Save a shortlist. Store the picks in a list with one link you can send to a cofounder or client.
The assistant still does what it is good at: understanding your brief, asking follow-up questions, and explaining why a name fits. The tool handles the part it cannot do.
How to connect NameStation to your assistant
NameStation runs a remote MCP server, so there is nothing to install or host. Every app uses the same server address and the same NameStation sign-in. You approve the connection on namestation.com, pick the account to bill, and can set a monthly credit cap for that app.
- ChatGPT: in Plugins, choose the plus button, then Add custom MCP server. This needs a Business, Enterprise, or Edu workspace on the web. See the ChatGPT setup guide.
- Claude: one click opens the custom connector form with NameStation filled in, in Claude.ai or Claude for desktop. See the Claude setup guide.
- Gemini: add NameStation as a custom app under Connected apps in the Gemini app. See the Gemini setup guide.
- Grok: add a custom connector on grok.com, install the plugin in Grok Build, or pass the server as a tool in a bot built on the xAI API. See the Grok setup guide.
- Slack: each person connects their own account and asks Slackbot in any channel. See the Slack setup guide.
- Coding agents: Claude Code, Codex, GitHub Copilot, Grok Build, and Gemini CLI install the NameStation plugin with one command, and Cursor, VS Code, Windsurf, and Antigravity add the server directly. Start with the plugin list or the Cursor guide.
Building a bot or an automation instead? Use a personal API key with the REST API, or connect Zapier, n8n, or Make with a single HTTP step. All the options are on the integrations page.
Prompts that get better names
Once the tool is connected, you do not need special syntax. Ask the way you would ask a person, and be specific about what matters to you:
- "Find 10 one-word .com names for a cozy coffee shop in Portland."
- "I like Brightnest. Find names in that style, but shorter, and skip anything you already showed me."
- "Is brightnest.com taken? Check .io and .co too."
- "Give me invented names for a budgeting app for freelancers. Under 8 letters, easy to spell, .com or .app."
The details that improve results are the same ones a naming consultant would ask about: who the customer is, the tone you want, words to avoid, the extensions you would accept, and a maximum length. If the first list misses, say what you liked and what you did not. The assistant can pass that feedback into the next search.
From shortlist to decision
A list of available domains is a starting point, not a decision. Before you register anything:
- Screen the top three to five names for trademarks. A domain can be free while the name conflicts with an existing mark in your market. Ask the assistant to screen your shortlist and look at any name flagged for caution before you commit.
- Say each name out loud. If you have to spell it every time you say it, it will cost you referrals.
- Save the shortlist and share it. Ask the assistant to save your favorites to a list, then send the link to the people who have a say. Collecting reactions on one page beats a long chat thread.
- Register quickly. Availability changes constantly. When a name survives the checks, register it before someone else does.
What it costs
Using NameStation from an assistant needs a paid plan or the free 3-day trial. New accounts can start the trial from the connect screen and come straight back to finish connecting.
A search from an assistant costs the same as on the website: generating names or finding available domains uses 10 credits, and finding available domains only charges when at least one domain is available. Checking domains, screening trademarks, and saving lists do not use credits. You can cap what each app spends per month and disconnect it any time from Connected apps in your settings.
Keep the connection safe
A connected app acts on your account, so treat it like any other login:
- Use the official server address. For NameStation, that is
https://api.namestation.com/mcp. If a directory offers one-click install, check that the address matches. - Approve only the access you need. The approval screen lists what the app can do and which account it bills.
- Set a cap. A monthly credit cap stops runaway usage if an agent loops.
- Keep API keys out of chats. Use sign-in for chat apps, and put keys only in bot or automation settings.
- Watch for prompt injection. Web pages and files can carry hidden instructions. Review what an agent does with its other tools, especially ones that can send messages or spend money.
The short version
AI assistants are excellent brainstorming partners and unreliable domain checkers. Connect a live domain tool and you keep the brainstorming while losing the guesswork. Every name the assistant calls available is one you can register today, and the whole loop, from brief to shortlist to trademark check, happens in the chat you were already using.
