Sonic Pi MCP server

The mcp-sonic-pi server connects any MCP (Model Context Protocol) client with Sonic Pi, making it possible to create music using natural language prompts. With this bridge between AI language models and Sonic Pi's sound generation capabilities, you can control music creation through conversational English.

Requirements

• Python 3.10 or higher
• Sonic Pi application installed and running on your system

Installation

Install the mcp-sonic-pi server using the Universal Executor (uvx):

uvx mcp-sonic-pi

Usage

Basic Setup

Before starting the MCP server, ensure that:

1. Sonic Pi application is running on your system
2. You have an MCP client configured to communicate with the server

Connecting with Claude

To use mcp-sonic-pi with Claude as your MCP client, add the following configuration to your claude_desktop_config.json file:

{
  "mcpServers": {
    "sonic-pi": {
      "args": [
        "mcp-sonic-pi"
      ],
      "command": "/path/to/uvx"
    }
  }
}

Make sure to replace /path/to/uvx with the actual path to your uvx executable.

Starting the Server

To start the MCP server, run:

uvx mcp-sonic-pi

Important: Always ensure Sonic Pi is running before starting the MCP server, otherwise the connection will fail.

How to add this MCP server to 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 > MCP and click "Add new global MCP server".

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

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

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 explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
