“Use “check_llc_name”: Is this LLC name available, and can it be registered in these states? Returns a dated preliminary or live verdict for each state, the source.”
“Use “check_trademark_conflicts”: Could this business name conflict with a federal trademark? Returns matching marks, status, classes, owner, record links, the register date,.”
“Use “check_domain_availability”: Is this domain available or taken? Check a name across up to five TLDs using a registered-zone index, live DNS, and the registry's RDAP reco.”
How secure is the BizNameChecker MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how BizNameChecker holds up.
Security grade A
gate scanned 7 tools on Nov 12, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by BizNameChecker (biznamechecker.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If BizNameChecker adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

https://biznamechecker.com/mcpQuestions, answered
