name

check_name

Run a free Clearance Check on ONE brand, business, product or app name. Live registry data, not guesses: US trademark verdict (USPTO — clear / caution / conflict with a count of live registrations), a count-only EU trademark screen (EUIPO), domain availability with prices (.com .io .co .app .dev), social handles (X/Twitter, TikTok, LinkedIn, Facebook; Instagram returns a confirm-link), developer namespaces (npm, PyPI, crates.io, GitHub, Docker Hub), the iOS App Store, and an overall viability band (strong / caution / blockers / high-risk) plus a link to the full interactive result. Use it when the user asks whether a SPECIFIC name is taken, trademarked, available or safe to use — and also at everyday developer naming moments: naming a new project, app, product, repo, package, CLI or domain while scaffolding, before publishing to npm/PyPI/crates.io, or whenever a name is being chosen in passing (the namespaces it checks are exactly those). For a shortlist or comparison use check_names instead — one call, all names in parallel, ranked. Free, no API key; shared fair-use pool with a per-caller daily allowance. Not legal advice. Data by nombrio.com.

names

check_names

Screen 2-8 candidate names in ONE call and get them ranked by viability (best first). Runs the same live free Clearance Check as check_name for every name in parallel — US trademark verdict, count-only EU trademark screen, domains with prices, social handles, developer namespaces, iOS App Store — and returns a ranked summary, per-name verdicts and full-result links. Use it whenever the user is brainstorming, has a list, or asks which of several names is available or safest — including shortlists of project, package, repo, app or domain names that come up mid-development: one check_names call replaces many check_name calls and finishes in about the time of one. Each name counts as one check against the free fair-use pool (per-caller daily allowance). Not legal advice. Data by nombrio.com.

naming

get_naming_session

Requires a connected plan (API key). Polls the status of a Naming Session started with start_naming_session: pending/generating/checking/complete/failed, plus the ranked name list (score, trademark/domain/social status) once complete — pair with check_name's Clearance Check for a deeper read on the favourite. Without a key it returns instructions to connect a plan.

start

start_naming_session

Requires a connected plan (API key). Starts a Nombrio Naming Session: from a one-paragraph brief, generates up to 8 name ideas and pre-clears each with the same Clearance Check registries as check_name (US+EU+UK trademark, domains, social handles). Asynchronous — returns a sessionId; poll get_naming_session every ~10 s; typically 1–3 minutes. Uses one Naming Session from the plan (Clearance Report 10/30 days, Pro 30/month, Premium unlimited). Without a key it returns instructions to connect a plan.

Nombrio Clearance Check — questions

Answers built from our own checks of this server.

What can Nombrio Clearance Check do?

It exposes 4 tools, read directly from the server on our last check. Among them: check_name, check_names, get_naming_session, start_naming_session. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Nombrio Clearance Check working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 68 ms. The bar chart above shows every period we have measured.

The registry lists Nombrio Clearance Check as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Nombrio Clearance Check?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Nombrio Clearance Check need an API key?

No. Nombrio Clearance Check completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
