MCP Audio Inspector

A Model Context Protocol (MCP) server for comprehensive audio file analysis and metadata extraction, designed specifically for game audio development workflows.

Features

• Comprehensive Metadata Extraction: Uses music-metadata library for detailed audio analysis
• FFprobe Fallback: Handles exotic and corrupted formats through FFprobe
• Game Audio Analysis: Specialized analysis for game development use cases
• Batch Processing: Analyze entire directories of audio files
• MCP Integration: Seamless integration with Claude Desktop
• Cross-Platform: Works on Windows, macOS, and Linux

Installation

npm install -g mcp-audio-inspector

Or use with npx:

npx mcp-audio-inspector

Usage

MCP Server Mode (Claude Desktop)

Add to your Claude Desktop configuration:

      "command": "npx",
      "args": ["-y", "mcp-audio-inspector"],
      "env": {}
    }
  }
}

Standalone CLI Mode

Analyze a single file:

npx mcp-audio-inspector --standalone path/to/audio.mp3

Batch analyze a directory:

npx mcp-audio-inspector --batch path/to/audio/directory

Save output to file:

npx mcp-audio-inspector --standalone audio.wav --output analysis.json

Supported Formats
