ocadaruma mcp svstudio

MCP server for Synthesizer V AI Vocal Studio, which allows LLMs to create/edit vocal tracks e.g. adding lyrics to the melody.

• Node.js (tested with v22)
• Synthesizer V Studio (tested with V2)

git clone https://github.com/ocadaruma/mcp-svstudio.git

• Copy below two files to Synthesizer V Studio scripts folder (On MacOS with V2 Studio, it's ~/Library/Application Support/Dreamtonics/Synthesizer V Studio 2/scripts by default)
  • sv-scripts/StartMCPServerRequestHandler.lua
  • sv-scripts/StopMCPServerRequestHandler.lua
• Run StartServerRequestHandler on Synthesizer V Studio
  • From Scripts menu > MCP > StartServerRequestHandler
  • ⚠️ Please do this before configuring MCP client. Otherwise, you will get connection issue.

⚠️ Please run only one MCP server at a time.

Add below config to the MCP server config of your client. (e.g. On MacOS Claude Desktop, it's ~/Library/Application Support/Claude/claude_desktop_config.json by default)
