Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Ableton Copilot Create a four-on-the-floor drum pattern in A minor"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Ableton Copilot connects Ableton Live to Claude AI through the Model Context Protocol (MCP), giving Claude a music-theory-aware toolset to compose, arrange, mix, and sound-design inside a real Live session — not just a remote control, but a copilot that understands key, genre, and song structure.
Built on top of the open-source Ableton Live Remote Script and socket protocol originally created by Siddharth Ahuja (ahujasid/ableton-mcp) — that project handles the low-level Live Object Model plumbing; everything above it (music theory, generators, mixing, telemetry, session state) is this project's own layer.
Two-way communication: Connect Claude AI to Ableton Live through a socket-based server
Track manipulation: Create, modify, and manipulate MIDI and audio tracks
Mixing control: Set track volume, pan, mute, solo, and send levels
Instrument and effect selection: Claude can access and load the right instruments, effects and sounds from Ableton's library
Clip creation: Create and edit MIDI clips with notes
Music-theory-aware generation: Key- and genre-aware chord, bassline, and drum pattern generators, plus one-call section scaffolding
Arrangement view composition: Build full songs autonomously in Arrangement View, including sections like intro, buildup, drop, breakdown, and outro
Session control: Start and stop playback, fire clips, and control transport across Session View and Arrangement View
Anonymous telemetry: Usage tracking to help improve the tool (can be disabled)
Related MCP server: Ableton MCP
The system consists of two main components:
Ableton Remote Script (AbletonMCP_Remote_Script/__init__.py): A MIDI Remote Script for Ableton Live that creates a socket server to receive and execute commands
MCP Server (MCP_Server/server.py): A Python server that implements the Model Context Protocol and connects to the Ableton Remote Script
Ableton Live 10 or newer
Python 3.8 or newer
If you're on Mac, please install uv as:
brew install uvOtherwise, install from [uv's official website][https://docs.astral.sh/uv/getting-started/installation/]
⚠️ Do not proceed before installing UV
Follow along with the setup instructions video
Go to Claude > Settings > Developer > Edit Config > claude_desktop_config.json to include the following:
{
"mcpServers": {
"AbletonCopilot": {
"command": "uvx",
"args": [
"ableton-copilot"

}Run ableton-copilot without installing it permanently through uvx. Go to Cursor Settings > MCP and paste this as a command:
uvx ableton-copilot⚠️ Only run one instance of the MCP server (either on Cursor or Claude Desktop), not both
Follow along with the setup instructions video
Download the AbletonMCP_Remote_Script/__init__.py file from this repo
Copy the folder to Ableton's MIDI Remote Scripts directory. Different OS and versions have different locations. One of these should work, you might have to look:
For macOS:
Method 1: Go to Applications > Right-click on Ableton Live app → Show Package Contents → Navigate to:
Contents/App-Resources/MIDI Remote Scripts/
Method 2: If it's not there in the first method, use the direct path (replace XX with your version number):
/Users/[Username]/Library/Preferences/Ableton/Live XX/User Remote Scripts
For Windows:
Method 1: C:\Users[Username]\AppData\Roaming\Ableton\Live x.x.x\Preferences\User Remote Scripts
Method 2:
C:\ProgramData\Ableton\Live XX\Resources\MIDI Remote Scripts\
Method 3:
C:\Program Files\Ableton\Live XX\Resources\MIDI Remote Scripts\
Note: Replace XX with your Ableton version number (e.g., 10, 11, 12)
Create a folder called 'AbletonMCP' in the Remote Scripts directory and paste the downloaded '__init__.py' file
Launch Ableton Live
Go to Settings/Preferences → Link, Tempo & MIDI
In the Control Surface dropdown, select "AbletonMCP"
Set Input and Output to "None"
Ensure the Ableton Remote Script is loaded in Ableton Live
Make sure the MCP server is configured in Claude Desktop or Cursor
The connection should be established automatically when you interact with Claude
Once the config file has been set on Claude, and the remote script is running in Ableton, you will see a hammer icon with tools for the Ableton MCP.

The system uses a simple JSON-based protocol over TCP sockets:
Commands are sent as JSON objects with a type and optional params
Responses are JSON objects with a status and result or message
Creating complex musical arrangements might need to be broken down into smaller steps
The tool is designed to work with Ableton's default devices and browser items

Build a playable musical base from an empty (or clean) set in one call: key + tempo, section markers, and chords/bass/drums for the main section.
Does NOT create groups, load instruments, or set a loop — those still need
to be done by hand in Live (see the note field in the result). Tracks are
created plain/named/colored so they're easy to find and drag instruments onto.
Parameters:

mode: Scale/mode name, e.g. "major", "minor", "dorian", "phrygian_dominant"

Scored across 52 tools
Most tools target distinct resources and actions, with clear separation between tracks, clips, devices, browser, and arrangement. Minor ambiguity exists between create_clip (MIDI) and create_audio_clip, as well as between get_clip_notes and get_arrangement_clip_notes, but descriptions and parameter scopes help.
Tool names consistently use lowercase snake_case with a verb-first pattern (get_, set_, create_, delete_, etc.). Deviations include some phrasal names like switch_to_arrangement_view and duplicate_to_arrangement, and create_clip is not as specific as create_midi_clip, which breaks symmetry with create_audio_clip.
At 52 tools, this server is heavily over-scoped compared to typical MCP servers, even for a broad DAW control domain. Many granular mixer tools (set_track_volume, set_track_pan, set_track_mute, etc.) could be combined, and the sheer volume increases cognitive load.
The tool surface covers core workflows: track/clip lifecycle, device manipulation, browser access, arrangement navigation, and music generation. However, there are notable gaps such as no direct editing of arrangement MIDI clips, no track duplication, no get_current_time, and no set_selected, which agents may need to work around.
