VOCALOID6 MCP 服务器

让 AI（通过 MCP 协议，在 atomcode 客户端中调用）自动作曲并驱动本机 VOCALOID6 编辑器， 产出可渲染歌声的工程文件（.vpr / .vsqx）。

用户输入歌词/想法
   ↓
[MCP 工具] compose_song      → 生成旋律 MIDI（MIDI-GPT 或降级模板）
   ↓
[MCP 工具] midi_to_vocaloid  → MIDI + 歌词 → .vpr 工程文件
   ↓
[MCP 工具] open_in_vocaloid6 → 自动打开 VOCALOID6 编辑器
   ↓
你在编辑器里点渲染 → 得到歌声 WAV

方案定位

  • 方案 A（当前实现）：AI 产出 VPR/VSQX 工程文件 + 自动打开编辑器，你点一下渲染。零脆弱点。
  • 方案 B（预留）：UI 自动化自动渲染 WAV（render_wav，pywinauto，后续阶段实现）。
  • 详细设计见 ../all-in-one-ai-midi-pipeline/docs/vocaloid6-mcp-design.md。

安装

cd /d/MIDI/vocaloid6-mcp
python -m venv .venv
.venv\Scripts\activate
pip install -r requirements.txt

启动 MCP 服务器

python server.py

接入 atomcode 的 MCP 配置后，AI 即可调用以下工具：

工具 功能
compose_song 歌词/想法 → 旋律 MIDI（MIDI-GPT 或降级模板）
midi_to_vocaloid MIDI + 歌词 → .vpr/.vsqx 工程文件
mix_songs 两曲混合改编（旋律/歌词/分段/infill）
lyric_correct 日文歌词 → 音节/音素预检
open_in_vocaloid6 打开工程文件到 VOCALOID6 编辑器
