16bits-gaudio-mcp

A Zig-powered MCP server that generates game audio — loopable BGMs, sound effects, and jingles — as 16-bit PCM WAV files.

Claude calls the tools, and .wav files come out. That's it.

• Zero external dependencies (Zig standard library only)
• 16-bit PCM WAV output
• FM synthesis, Schroeder reverb, ADSR envelopes, multi-track mixing

brew tap Matuyuhi/tools
brew install 16bits-audio-mcp

curl -fsSL https://raw.githubusercontent.com/Matuyuhi/16bits-gaudio-mcp/main/install.sh | bash

git clone https://github.com/Matuyuhi/16bits-gaudio-mcp.git
cd 16bits-gaudio-mcp
make install   # installs to ~/.local/bin

Or just:

zig build
# binary: zig-out/bin/16bits-audio-mcp

Add to ~/.claude/settings.json:

{
  "mcpServers": {
    "16bits-audio": {
      "command": "16bits-audio-mcp"
    }
  }
}

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "16bits-audio": {
      "command": "16bits-audio-mcp"
    }
  }
}

If you built from source, use the full path instead:

{
  "mcpServers": {
    "16bits-audio": {
      "command": "/path/to/zig-out/bin/16bits-audio-mcp"
    }
  }
}

Generate loopable BGM with 4 tracks (melody, bass, harmony, percussion).
