Overview

AI-generated overview

Checks brand, product or app names against live trademark, domain, social and app-store registries, and runs paid naming sessions.

What you can do
  • Check one name against live registries: US trademark verdict, EU trademark count, domain availability with prices, social handles, developer namespaces and iOS App Store.
  • Screen and rank 2-8 candidate names in a single call by viability.
  • Start a Naming Session from a brief to generate up to 8 name ideas, each pre-cleared against trademark, domain and social registries.
  • Poll a Naming Session for status and the ranked results once complete.
When to use it
Useful when choosing a brand, business, product or app name and you want quick evidence on trademark conflicts, domain availability and handle availability before committing. The batch tool suits comparing a shortlist; naming sessions suit going from a brief to pre-cleared ideas.
Requirements
Remote HTTP endpoint at nombrio.com; no local install. Works without credentials on a free tier. Full Clearance Checks and Naming Sessions need a connected plan and an Authorization header carrying a Bearer API key.
Before you install
The Authorization header carries a Nombrio API key; keep it private. Naming Sessions and full checks require a paid plan, so usage may incur cost. Results are registry screens, not legal advice, and the EU trademark check is count-only. The service sends your candidate names and brief to a third party.

Installation

In SourceWeft

  1. Open Nombrio Clearance Check in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.nombrio%2Fname-check/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

check_name

Clearance Check — one name (free)

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.

check_names

Clearance screen — 2 to 8 names at once (free)

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.

Parametersnamesrequired

start_naming_session

Naming Session — 8 pre-cleared names from a brief (your plan)

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.

ParametersbriefrequiredabstractionLevelsoundPersonality

get_naming_session

Naming Session status (your plan)

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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
