Technical Details

what runs on :9801

SSTP uses a plain-text, HTTP-like request/response format: a client sends a request line and headers, with any command or Sakura Script content in the message, and the server returns a status response. Port 9801 is the registered SSTP-2 port; implementations commonly use it for a local TCP listener, although the registry also lists UDP. It is not TLS-encrypted, and the exact supported commands and character encodings depend on the receiving runtime.

security overview

This endpoint is intended for communication with desktop-mascot software, typically on the same machine. If exposed beyond localhost, a reachable client may be able to submit commands or scripts to the runtime; authentication and authorization behavior varies by implementation. Keep it bound to loopback or restrict it to trusted hosts rather than exposing it to the internet.
