Connects to state LLC naming records, the USPTO trademark register, domain RDAP and DNS data, and 23 social platforms. Muse can screen a proposed business name across all four areas at once and return dated verdicts, sources and a results link.

Example request: "Is Blue Fern Coffee available as an LLC in Oregon, and is the .com and the Instagram handle free?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use BizNameChecker to help me. It is a free service with an MCP server at https://biznamechecker.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
