**Setup Video** · **Discord** · **Issues**

Quickstart

Three steps: install uv, point your MCP client at the server, install the Ableton Remote Script.

1. Install uv

# macOS
brew install uv

Otherwise, install from uv's official website.

Warning: Do not proceed before installing uv.

2. Add the MCP server to your client

Claude Desktop — Settings → Developer → Edit Config

{
"mcpServers": {
"AbletonMCP": {
"command": "uvx",
"args": [
"ableton-mcp"
]
}
}
}

Cursor — Settings → MCP

Paste this as a command:

uvx ableton-mcp
Warning: Only run one instance of the MCP server (either on Cursor or Claude Desktop), not both.

3. Install the Ableton Remote Script

uvx --from ableton-mcp ableton-mcp-install-script
uvx --from ableton-mcp ableton-mcp-install-script --list-targets   # preview target folders first

4. Connect

  1. Launch Ableton Live
  2. Go to Settings/Preferences → Link, Tempo & MIDI
  3. In the Control Surface dropdown, select AbletonMCP
  4. Set Input and Output to None

That's it — ask Claude to build

Questions

What is the Ableton MCP server?

Control Ableton Live with any LLM: create tracks, arrange clips & compose music via MCP

What tools does Ableton expose?

1 in total: 0 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Ableton safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Ableton need?

It reads ABLETON_MCP_PASSIVE_POLL_SEC, ABLETON_MCP_PASSIVE_SNAPSHOT_DEBOUNCE and ABLETON_MCP_SUPABASE_SERVICE_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How current is this page?

The grade is for one exact copy of the source (07553cc80eb7), read on 2026-09-22. The repository is watched and re-audited when it changes.
