Ableton Mind

ableton-mind

Definitive MCP (Model Context Protocol) server for Ableton Live. Exposes the full Live Object Model to LLMs (Claude, Cursor, etc.) with an embedded native device knowledge base, declarative music recipes, an integrated verify loop, and reactive listeners.

Status: alpha / v0.1.1 published — core smoke passed against Ableton Live 12.4.1 on macOS and package validation is green. npm, GitHub Release .mcpb, and the MCP Registry are live. Glama has a listing, but its hosted release/deploy must be published separately from the Glama admin build flow; Smithery metadata is present and may lag indexing. API unstable. Don't use in production yet.

Phase 8 status: slice 1 delivers read-only Max for Live/plug-in introspection and Link/remote status discovery. Deeper M4L control, VST3 sidecars, remote DAW integration and mobile companion work remain pending.

Architecture (3 layers)

Claude/Cursor ──MCP/stdio──▶ ableton-mind (TS, Node 20+) ──TCP NDJSON JSON-RPC──▶ Remote Script (Python, inside Live)

• src/ — TypeScript MCP server. Tools, resources, prompts, TCP client, recipe runner, knowledge loader.
• live/AbletonMind/ — Python Remote Script. TCP server on port 9876, dispatches JSON-RPC to LiveAPI.
• recipes/, src/knowledge/ — embedded JSON (drum kits, basslines, racks, device schemas).

Full spec in PLAN.md. Frozen contracts in _workspace/contracts/.

Requirements

• Node 20+
• Ableton Live 12 (priority; Live 11 supported)
• macOS (primary), Windows (Phase 1 final)

Setup (source install)

npm install
npm run typecheck
npm run lint
npm run test
npm run build

Install Remote Script (Python bridge)

Dev mode (symlink):

node scripts/install-remote-script.mjs           # creates symlink
node scripts/install-remote-script.mjs --check   # status only
node scripts/install-remote-script.mjs --copy    # full copy (CI / snapshot)

Manual:

• macOS: copy live/AbletonMind/ to ~/Music/Ableton/User Library/Remote Scripts/AbletonMind/
• Windows: copy to ~/Documents/Ableton/User Library/Remote Scripts/AbletonMind/

Then Live → Preferences → Link/Tempo/MIDI → Control Surface → AbletonMind.

Smoke test: docs/smoke-test.md.

Run the MCP server

npm run build
node dist/index.js

Env vars:

Var	Default
ABLETON_MIND_HOST	127.0.0.1	Python bridge host
ABLETON_MIND_PORT	9876	Bridge TCP port
ABLETON_MIND_TIMEOUT_MS	5000	Per-request timeout
ABLETON_MIND_MAX_FRAME_BYTES	1048576	Max incoming JSON-RPC frame
ABLETON_MIND_MAX_PENDING_REQUESTS	128	Max in-flight JSON-RPC calls
ABLETON_MIND_LOG_LEVEL	info	debug | info | warn | error

Local copilot

Run a local LLM against a curated subset of the same Ableton tools:

ollama pull qwen2.5:3b      # optional; the UI can pull too
node dist/index.js chat     # opens http://127.0.0.1:4142
node dist/index.js ask "What is in this set?"

The default tier is read-only (safe). Use --write for simple changes or --creative for recipes/browser load.

Var	Default
ABLETON_MIND_LLM_BASE_URL	http://127.0.0.1:11434/v1	OpenAI-compatible endpoint
ABLETON_MIND_LLM_MODEL	qwen2.5:3b	Local model id
ABLETON_MIND_LLM_TIER	safe	safe | standard | creative
ABLETON_MIND_CHAT_PORT	4142	Browser UI port

See Local copilot.

Doctor CLI

npx ableton-mind-doctor

Checks Node version, Remote Script install, bridge port, knowledge base integrity, recipes.
