Enables audio playback functionality on macOS systems using AFPlay and SimpleAudio, allowing for notification sounds with support for custom audio files.
MCP Play Sound Server
A Model Context Protocol (MCP) server that provides audio playback functionality for AI agents. This server enables AI agents to play sound notifications when coding tasks are completed.
⚠️ Early Version / Proof of Concept This is an early implementation currently tested only on macOS. Future versions will support additional platforms.
Features
- Audio Notifications: Play sound alerts when AI tasks complete
- Default Sound: Bundled notification sound for immediate use
- Custom Audio: Support for custom audio files (WAV, MP3, FLAC, OGG, M4A)
- Intelligent Fallback: Automatic fallback to default sound if custom audio fails
- macOS Support: Currently tested on macOS using AFPlay and SimpleAudio
Installation & Setup
Development Setup
- Clone and install:
- Configure Claude Desktop:
Add to your
claude_desktop_config.json
:
- Test: Restart Claude Desktop and ask: "Can you play a notification sound?"
