Next.js TypeScript MCP License: MIT Zero API keys

Vet a product name in seconds. Domains, App Store, Google Play, web and trademark registers in one check. Use it in the browser, or hand a shortlist to your AI agent over MCP.

Why

Picking a name means opening a registrar, two app stores, Google and two trademark registers, for every candidate. Namevet does the first screen for you: paste a list, get a ranking, and only open the registers for the names that survive.

Related MCP server: domain-mcp

Features

  • Domains. 10 TLDs per name via RDAP (authoritative), with a DNS fallback for TLDs without RDAP.

  • Free alternatives. Tries other TLDs, prefixes (get, try, use) and suffixes (app, hq, labs) and returns what is free.

  • App Store and Google Play. Exact, similar or no match, with the competing listings.

  • Web. Exact-phrase search: inline results with a Google or Brave key, deep links without.

  • Trademark registers. DPMA, EUIPO, TMview and WIPO links with Nice classes 9, 35 and 42.

  • Ranking. A 0-100 score per name, so a list of 25 becomes an ordered shortlist.

  • GitHub. Optional handle and repo-name check for developer tools, via MCP.

  • Creative naming skill. A Claude Code skill that invents non-generic names and vets them with Namevet.

  • MCP server. Eight tools, including check_names for whole lists. Works with Claude, Codex, Gemini CLI, Cursor, VS Code and anything that speaks MCP.

  • No database, no required keys. One Next.js app, deploys to Vercel in a minute.

Quick start

npm install
npm run dev

Open http://localhost:3000, paste one or more names (comma or line separated), press Enter.

What it checks

Check

Source

Confidence

Domains

RDAP (.com, .de, .app, .dev, .ai, ...). TLDs without RDAP (.io, .co, ...) use a DNS lookup, marked dns guess

RDAP: high. DNS: heuristic

Suggestions

Variants of the name, each checked like a normal domain

same as above

App Store

iTunes Search API

good

Google Play

google-play-scraper (unofficial, can break when Google changes markup)

good, fragile

Web

Google Programmable Search or Brave Search if a key is set, otherwise links

links only without a key

Registers

Deep links to DPMAregister, EUIPO eSearch, TMview, WIPO Brand DB

manual review

IMPORTANT

DPMA, EUIPO and TMview have no free public search API, so those are deliberate link-outs. A free domain and "no store match" arenot trademark clearance. Review the registers for every name you shortlist.

Score

score = domains (50) + stores (50). .com is worth 22, .de 18, the other TLDs up to 10; each store gives 25 for no match, 12 for similar names, 0 for an exact match. It is a screening heuristic, not legal advice.

Use with AI agents

The MCP endpoint is /mcp (Streamable HTTP). Replace <URL> with http://localhost:3000/mcp or your deployed https://.../mcp. The home page shows the same snippets with copy buttons and your own URL filled in.

Agent

Setup

Claude Code

claude mcp add --transport http namevet <URL> (add --scope user for all projects), or .mcp.json: {"mcpServers":{"namevet":{"type":"http","url":"<URL>"}}}

Claude Desktop

claude_desktop_config.json: {"mcpServers":{"namevet":{"command":"npx","args":["-y","mcp-remote","<URL>"]}}}, then restart. With a public https URL: Settings > Connectors > Add custom connector

claude.ai

Public https URL required. Settings > Connectors > Add custom connector. No static bearer token support, so leave MCP_AUTH_TOKEN unset

Codex

codex mcp add namevet --url <URL>, or ~/.codex/config.toml: [mcp_servers.namevet] with url = "<URL>"

Gemini CLI

gemini mcp add --transport http namevet <URL>

Cursor

.cursor/mcp.json: {"mcpServers":{"namevet":{"url":"<URL>"}}}

VS Code (Copilot)

.vscode/mcp.json: {"servers":{"namevet":{"type":"http","url":"<URL>"}}}

Anything else

Any client with Streamable HTTP. stdio-only clients: npx -y mcp-remote <URL>

Auth is optional. Set MCP_AUTH_TOKEN and the server requires Authorization: Bearer <token>. Add it with --header "Authorization: Bearer <token>" (Claude Code, Gemini CLI) or --bearer-token-env-var (Codex).

Then just ask:

Use namevet to check these names and rank them: Assay, Plumb, Tidepool. Then show trademark links for the best two.

Skill: creative naming

skills/creative-naming/SKILL.md teaches an agent to invent names that do not read like generated slop (no -ly, -ify, Nova or Lumora-style mashups), then vet them through Namevet before recommending anything. It works best together with the MCP server above.

Install

# any agent, detects what you have installed
npx skills add MikaStiebitz/Namevet

# Claude Code (all projects)
curl -fsSL https://raw.githubusercontent.com/MikaStiebitz/Namevet/main/skills/creative-naming/SKILL.md \
  --create-dirs -o ~/.claude/skills/creative-naming/SKILL.md

# Codex and Gemini CLI
curl -fsSL https://raw.githubusercontent.com/MikaStiebitz/Namevet/main/skills/creative-naming/SKILL.md \
  --create-dirs -o ~/.agents/skills/creative-naming/SKILL.md

A deployed Namevet also serves the file at /skill.md, and the home page has copy and download buttons. For project-only use, put it in .claude/skills/creative-naming/ (Claude Code) or .agents/skills/creative-naming/ (Codex, Gemini CLI). For Claude Desktop or claude.ai, zip the creative-naming folder and upload it under Settings > Capabilities > Skills.

Then ask: "Invent names for a privacy-first note app. Use creative-naming."

Tools

Tool

What it does

check_names

Batch. Up to 25 names in, ranked result out: score, free and taken domains, store verdicts, notes. details: true for full data

check_name

Full check of one name

check_domains

Availability per TLD

suggest_domains

Free alternative domains

check_app_stores

App Store and Google Play

check_github

GitHub user/org handle and repo name collisions (set GITHUB_TOKEN for batches)

check_web

Exact-phrase web search

trademark_links

DPMA, EUIPO, TMview, WIPO links with Nice classes

HTTP API

curl "http://localhost:3000/api/check?name=Namevet&tlds=com,de,app"
curl "http://localhost:3000/api/suggest?name=Namevet"

Configuration

Everything is optional. Copy .env.example to .env.local.

Variable

Effect

GOOGLE_CSE_KEY, GOOGLE_CSE_CX

Inline Google results and result count in the Web section

BRAVE_API_KEY

Inline Brave results instead (used if no Google keys)

GITHUB_TOKEN

Raises GitHub API limits for check_github (unauthenticated: 10 searches per minute)

MCP_AUTH_TOKEN

Require a bearer token on /mcp

NEXT_PUBLIC_CONTACT_EMAIL

Shown on /impressum

Deploy

npx vercel

or import the repository in Vercel. It needs no build settings. The web page and /api/* have no authentication, so add rate limiting or protect the deployment if you make it public.

Project layout

app/            pages, /api routes, the /mcp server and /skill.md
components/     UI (checker, ranking, cards, agent setup guide)

Roadmap

  • EUIPO trademark API integration (needs registered credentials)

  • Social handle checks (X, Instagram) and npm / PyPI package names

  • Retry and caching for registry lookups

  • Shareable result links

Impressum

The /impressum page holds the provider details required in Germany (§ 5 DDG). Set your own details in app/impressum/page.tsx if you fork this.
