vocaloid6-mcp
Allows converting MIDI files to VOCALOID6 projects, enabling vocal synthesis from existing melodies.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@vocaloid6-mcpCompose a song from this lyric and open it in VOCALOID6."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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] list_voicebanks → 查看本机可用歌姬(MIKU_V4X 系列等)
↓
[MCP 工具] compose_song → 歌词+歌姬+情感+歌曲结构 → 旋律 MIDI → .vpr 工程
↓
[MCP 工具] midi_to_vocaloid → 已有 MIDI + 歌词 → .vpr 工程
↓
[MCP 工具] open_in_vocaloid6 → 自动打开 VOCALOID6 编辑器
↓
[MCP 工具] render_wav → UI 自动化渲染导出 WAV(尽力实现,失败给手动兜底)
↓
得到歌声 WAV方案定位
方案 A: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:pywinauto UI 自动化自动渲染 WAV(
render_wav,尽力实现,失败时返回明确错误与手动步骤)。

安装
cd C:/Users/Admin/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(C:/Users/Admin/.atomcode/mcp.json 已指向本项目),AI 即可调用以下工具:
工具 | 功能 |
| 列出本机可用歌姬(真实声库 + V6 内置 AI 声库) |
| 歌词/想法 → 旋律 MIDI → .vpr 工程(支持歌姬/情感/歌曲结构) |
| 已有 MIDI + 歌词 → .vpr/.vsqx 工程(支持歌姬/情感) |
| 两曲混合改编(旋律/歌词/分段/infill) |
| 日文假名 → 音节/音素;中文 → 拼音(支持自定义读音) |
| 打开工程文件到 VOCALOID6 编辑器 |
| UI 自动化渲染导出 WAV(pywinauto,尽力实现) |
完整写歌示例(AI 调用链)
list_voicebanks→ 找到MIKU_V4X_Original_EVEClyric_correct("我爱月光照亮黑夜", lang="zh")→ 预检中文拼音compose_song(lyrics="我爱月光照亮黑夜", voice="MIKU_V4X_Original_EVEC", emotion="sad", structure="pop", key="Am", scale="minor")→ 生成 .vpr/.vsqxopen_in_vocaloid6(vpr_path)→ 打开编辑器试听render_wav(vpr_path, output_wav="out.wav")→ 尝试自动渲染 WAV
参数速查
voice 歌姬:
list_voicebanks返回的 name 或 comp_id;中文用户常用MIKU_V4X_Original_EVEC(初音未来)emotion 情感:happy/sad/gentle/passionate/rock/calm(或中文:快乐/悲伤/温柔/激昂/摇滚/平静),控制力度/开音/颤音/音域和 Part 控制器曲线
structure 结构:pop / simple / ballad(和弦进行 + 主歌/副歌/桥段/尾声)
key 调性:C / Dm / Eb / F#m 或数字 0-11
scale 音阶:major / minor / pentatonic / minor_penta
