Check brand names from your AI assistant
Live trademark, domain & handle checks — without leaving the chat
Nombrio ships a Model Context Protocol (MCP) server. Connect it once and your AI assistant can run a real availability check on any name it suggests — against the US trademark registry, domains, social handles, developer namespaces, and the App Store — while you brainstorm.

- Streamable HTTP

- None
- Tools
- check_name
What the check_name tool returns
One call per candidate name. Every result is live availability data at check time — not model guesswork — and includes a link to the full interactive result in the browser.
US trademark verdict (USPTO)
Clear / caution / conflict against live US registry data — including how many potentially conflicting registrations exist and their Nice classes.
Domains with prices
.com, .io, .co, .app, .dev availability with registration prices.
Social handles
X/Twitter, Instagram, TikTok, and LinkedIn handle availability.
Developer namespaces
npm, PyPI, crates.io, GitHub, and Docker Hub — for naming a library or tool.
iOS App Store
Whether similar-named apps already exist on the App Store.
Viability band + full result link
An overall viability estimate, plus a link to the full interactive result in the browser.
The free tool covers the US register. UK IPO + EU IPO coverage, the named conflicting marks, and the exact risk score are in the $9.99 Clearance Report.
Set up in your client
Works with any MCP-capable client over streamable HTTP. No account, no key — connect and ask your assistant to check a name.

https://nombrio.com/api/mcpFair use
The MCP server is free and shares a daily fair-use pool across all connected assistants. When the pool is exhausted, the tool still returns domain and handle data plus a link to run the complete check in the browser — which has its own quota. Results are informational screening, not legal advice.
