> An MCP (Model Context Protocol) server built on [ableton-js](https://github.com/leolabs/ableton-js) for real-time interaction and control with Ableton Live's Arrangement View, dedicated to assisting music producers in their music production.
## 🎯 Note
As a music producer, I have some understanding of using Ableton for music creation. During the creative process, we often need to handle various tedious operations, such as humanizing note properties, merging notes, recording one track to another audio track, etc. Previously, we could only rely on the functions provided by the host DAW for these operations. However, with the emergence of large language models and MCP, we now have the possibility to let AI help us with automation. Although it's still not realistic for AI to directly generate notes or create a complete song (it can't generate a good-sounding song), having AI assist us with auxiliary operations presents a new possibility.
## 🎥 Demo
This is a simple demonstration video of MIDI operations.

## 🚀 Features
### 🎵 Song Control
- Get basic song information (root note, scale name, tempo, song length, etc.)
- Get a list of all tracks
- Create MIDI, audio, and return tracks
- Delete and duplicate tracks
### 🎹 Track Management
- Get all clips in a track
- Create empty MIDI clips in the arrangement view tracks
- Create audio clips in tracks based on provided sample file paths
- Set track properties (mute, color, name, arm, solo, etc.)
- Duplicate MIDI clips to specified tracks
### 🎼 Clip Operations
- Get clips in the piano roll view
- Get and manage all notes in a clip
- Add, delete, and replace notes in clips
- Set clip properties (name, color, looping, loop_start, loop_end, etc.)
### 🎧 Audio Operations
- Supports recording track content based on time range
### 🔌 Device Management
- Load audio effects, instruments and plugins
- Modify device parameters
- Browse available devices in the library
### 📝 State Management
- Operation history tracking and detailed logging
- Support for operation rollback (currently only supports note operations)
- Browse and restore previous states
## 📝 To-Do List
- Support automatic envelope adjustment
- Support more snapshot types (track properties, device parameters, etc.)
## ⚠️ Warning
- Direct manipulation of MIDI clips by AI may result in the loss of original notes and cannot be undone with Ctrl + Z. Please operate with caution. If needed, you can ask the AI to help you roll back note operations.
## 📥 Installation
### Prerequisites
- **Node.js** environment: Ensure Node.js is installed (v20+ recommended) and the `npx` command is available
> 🔗 Download: [Node.js official website](https://nodejs.org/)
### Installation Steps
#### 1. Install AbletonJS MIDI Remote Scripts
Choose **ONE** of the following three methods to install MIDI Remote Scripts:
- **Method 1: One-line installation (Recommended)**
```bash
npx @xiaolaa2/ableton-copilot-mcp --install-scripts
# or use the short form
npx @xiaolaa2/ableton-copilot-mcp -is
```
- **Method 2: Tool-assisted installation**
1. First, start ableton-copilot-mcp (see Usage section below)
2. Let AI assistant or manually call the MCP tool `init_ableton_js` to complete the installation automatically
- **Method 3: Manual installation**
1. Create a folder named "Remote Scripts" in your Ableton User Library:
- Windows: `C:\Users\[username]\Documents\Ableton\User Library\Remote Scripts`
- Mac: `/Users/[username]/Music/Ableton/User Library/Remote Scripts`
2. Download MIDI Remote Scripts from the [ableton-js](https://github.com/leolabs/ableton-js) project
3. Copy the downloaded `midi-script` folder to the location above
4. Rename it to `AbletonJS`
## 🔧 Usage
### Quick Start
1. **Launch Ableton Live**
2. **Enable AbletonJS Control Surface**
- Open Ableton Live Preferences: `Preferences` → `Link/MIDI`
- In the `MIDI` tab, locate the `Control Surface` section
- Select `AbletonJS` from the dropdown menu

3. **Connect using an MCP client**
The following clients can be used as MCP endpoints:
- [Cursor](https://www.cursor.com)
- [Cherry Studio](https://github.com/CherryHQ/cherry-studio)
- Claude Desktop
- Other MCP clients
### Client Configuration
#### Cursor Configuration Example
Add the following configuration to your Cursor settings:
```json
"ableton-js-mcp": {
"command": "npx",
"args": [
"-y",
"@xiaolaa2/ableton-copilot-mcp"
]
}
```
For the latest version:
```json
"ableton-js-mcp": {
"command": "npx",
"args": [
"-y",
"@xiaolaa2/ableton-copilot-mcp@latest"
]
}
```
#### Custom Storage Path (Optional)
You can specify a custom data storage location using the `BASE_PATH` environment variable:
```json
"ableton-js-mcp": {
"command": "npx",
"args": [
"-y",
"@xiaolaa2/ableton-copilot-mcp"
],
"env": {
"BASE_PATH": "D:\\ableton_copilot_mcp"
}
}
```
> 💡 **Tip**: The storage path is used to save log files, operation history, and state snapshots
