Sound Effects MCP server

The MCP Sound Tool provides audio feedback for your coding experience by playing sound effects for various events in Cursor AI and other MCP-compatible environments. It enhances interactivity by adding audio cues for completions, errors, and notifications.

Installation

Python Version Compatibility

This package is tested with Python 3.8-3.11. If you encounter errors with Python 3.12+ (particularly BrokenResourceError or TaskGroup exceptions), please try using an earlier Python version.

Installing with pipx (Recommended)

pipx is the recommended installation method as it creates an isolated environment while making commands available globally:

# Install pipx if you don't have it
python -m pip install --user pipx
python -m pipx ensurepath

# Install mcp-sound-tool
pipx install mcp-sound-tool

Alternative: Installing with pip

You can also install directly with pip:

pip install mcp-sound-tool

Installing from Source

git clone https://github.com/yourusername/mcp-sound-tool
cd mcp-sound-tool
pipx install .

Or with pip:

pip install -e .

Usage

Adding Sound Files

Place your sound files in the sounds directory. The tool expects these files:

• completion.mp3 - Played after code generation
• error.mp3 - Played when an error occurs
• notification.mp3 - Used for general notifications

You can find free sound effects on websites like freesound.org.

Running the MCP Server

Start the server with:

mcp-sound-tool

The server will listen for events from Cursor or other MCP-compatible clients through the stdio transport.

Configuring in Cursor

To use this server with Cursor, add it to your MCP configuration file:

On macOS:

// ~/Library/Application Support/Cursor/mcp.json
{
  "mcpServers": {
    "sound": {
      "command": "mcp-sound-tool",
      "args": [],
      "type": "stdio",
      "pollingInterval": 5000,
      "startupTimeout": 10000,
      "restartOnFailure": true
    }
  }
}

On Windows:

// %APPDATA%/Cursor/mcp.json
{
  "mcpServers": {
    "sound": {
      "command": "mcp-sound-tool",
      "args": [],
      "type": "stdio",
      "pollingInterval": 5000,
      "startupTimeout": 10000,
      "restartOnFailure": true
    }
  }
}

Sound MCP Usage Guidelines

When to Use Sound Feedback

The server provides three types of sound feedback:

1. Success Sounds (completion)

   • After successful task completion
   • When confirming a user's request has been fulfilled

2. Error Sounds (error)

   • When a command has failed
   • When warning about a problem

3. Notification Sounds (notification)

   • When alerting the user to important information
   • When prompting for user attention or input

Available Tools

The MCP server provides these tools:

• play_sound(sound_type="completion", custom_sound_path=None): Play a sound effect
• list_available_sounds(): List all available sound files
• install_to_user_dir(): Install sound files to user's config directory

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "sound" '{"command":"mcp-sound-tool","args":[],"type":"stdio","pollingInterval":5000,"startupTimeout":10000,"restartOnFailure":true}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "sound": {
            "command": "mcp-sound-tool",
            "args": [],
            "type": "stdio",
            "pollingInterval": 5000,
            "startupTimeout": 10000,
            "restartOnFailure": true
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "sound": {
            "command": "mcp-sound-tool",
            "args": [],
            "type": "stdio",
            "pollingInterval": 5000,
            "startupTimeout": 10000,
            "restartOnFailure": true
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
