Official endpoint

Operated by b612 (hakuto AI) (hakuto-0209.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 b612 (hakuto AI) adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
