check_engine_status
Check if AivisSpeech engine is running
LABSCO SUMMARY
Your assistant can talk back, and tell you out loud when it is done.
It speaks through an AivisSpeech engine you run on your own machine, so the voices are Japanese and the audio is made locally.
What it is
A text-to-speech server for the AivisSpeech engine running on your machine: it turns text into natural-sounding Japanese speech and plays it through your speakers.
What you get
- Text spoken aloud with
speak, with speaker, speed, pitch and volume adjustable - The available voices and styles listed with
get_speakers(default voice: Anneli ノーマル) - A spoken notice when a task finishes, with
notify_completion - The engine's status and version checked with
check_engine_status
Requirements
A running AivisSpeech engine the machine can reach, with its address in AIVISSPEECH_URL.
Setup effort
One command — npx @shinshin86/mcp-simple-aivisspeech@latest
USE CASES
01
Confirming the speech engine is up before something depends on it
A silent failure downstream usually traces back to an engine that was never running. This answers that question directly.
02
Hearing the answer instead of reading it
Have the assistant speak a reply or a passage aloud in Japanese, in the voice and at the speed you pick.
03
Knowing a long task is done without watching the screen
Ask for a spoken notice when the work finishes, or add a line to CLAUDE.md so Claude Code announces it every time.
1 tool
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
BEFORE YOU INSTALL
What to know first
Tools you get
1 tool when we connected; the project documents 4. Documented tools are speak, get_speakers, notify_completion and check_engine_status. Only check_engine_status works without the AivisSpeech engine at http://127.0.0.1:10101; with no engine running the others may not appear.
Requires
- Node.js - Version 18.0.0 or higher
- AivisSpeech Engine - Running on http://127.0.0.1:10101 (default port)
Where it runs
Both documented clients run the server on your machine.
