Kokushin MCP Server

MCP server for generating Voiceroid explanation scenarios for Exia. Exposed over MCP by the kokushin mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

3. Claude Desktop で以下のように使用 - 「exia で量子コンピュータについて解説して」と入力 - MCP サーバが起動し、シナリオを生成して exia を起動 - exia アプリケーション（Electron）が別ウィンドウで起動し、シナリオをプレイ

Its toolset

Everything the assistant can do here goes through one of these:

• generateScenario — お題からシナリオを生成
• setupExia — exia をダウンロードしてセットアップ
• saveScenario — 生成したシナリオを保存
• exiaVoiceroidExplain — シナリオ生成から exia 起動までを一括実行（推奨）

Configuration

You will need one environment variable: YOUR_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

When to reach for it

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Kokushin's toolset — generateScenario, setupExia, saveScenario and 1 more — is a fair guide to whether it matches your workflow. It is maintained by chatflowdev; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Kokushin's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the kokushin mcp server does with a few real requests.
