Audio Studio MCP

Audio Studio MCP is an open-source MCP server from KanaWorks_AI that gives Claude Code, Claude Desktop, Cursor and other MCP clients a sound studio running on the user's own Mac or Windows PC. It generates background music, instrument loops and sound effects locally with Stable Audio 3. The README states there is no cloud service and no API key.

What It Is

Audio Studio MCP exposes audio generation, editing and post-processing as MCP tools. A user asks their MCP client in plain language for a BGM track or a sound effect, and the server builds a prompt in the Stable Audio 3 format, runs the model locally, and writes the result to disk. Each output file has a .json sidecar recording its prompt, seed and settings, so the same prompt and seed can reproduce the same file.

Tools and Workflow

• generate_audio turns text into music, instrument loops or stems, or sound effects. It returns 1–4 candidates per call and accepts a BPM value and structured SFX fields for source, action, material and space.
• edit_audio offers variation (re-style a whole clip), inpaint (regenerate a time range) and continue (extend a track).
• process_audio chains trimming, silence trimming, mono conversion, resampling, loudness normalization, seamless loop crossfade, fades and peak normalization, then exports WAV, OGG or FLAC without modifying the input.
• unload_models frees model memory immediately.

Generated files are 44.1 kHz 24-bit stereo WAV written to an outputs folder.

Local Backends and Setup

On Apple Silicon the server runs Stable Audio 3 through MLX. On Windows it uses PyTorch with an NVIDIA GPU, with 8 GB of VRAM or more required. The macOS installer needs about 6 GB of disk and recommends 16 GB of RAM. The Windows install needs about 14 GB of disk and a Hugging Face account to accept the model license. Both installers use git and ffmpeg, and register the server with claude mcp add.

Linux with an NVIDIA GPU is described as untested and without an installer. Intel Macs and AMD GPUs are not supported. The model produces instrumental music and sound effects, not intelligible vocals.

Licensing Notes

The project code is MIT-licensed. The Stable Audio 3 model weights fall under the Stability AI Community License, which governs use of the model and its output, so commercial users should read it first. The project says it is independent and not affiliated with Stability AI, Apple, NVIDIA or Anthropic.
