ableton-mcp

ableton-mcp is a skill for Claude Code, Codex from PerIPan/music-workflow-skills. It costs 55 tokens per session (3,454 once invoked), scanned A, original, MIT.

A set of instructions for controlling Ableton Live, music-production software, through an AbletonMCP server. It covers creating tracks, clips, and scenes; editing MIDI notes; loading instruments and effects; and changing mix or automation settings.

In plain words
What is it for?
Use it to create and edit Live projects, program MIDI, load sound devices, adjust effect settings, automate changes, mix tracks, and debug the Live connection.
Why use it?
It helps an agent work with Ableton Live while accounting for connection issues and the limits of the control interface. Ableton Live is a program for recording, arranging, and performing music.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

ModelPer sessionOnce invoked
Fable 5.1 $0.00055 $0.03454
Opus 5.5 $0.00022 $0.01382
Sonnet 5.5 $0.00011 $0.00691

Security

Grade A, and why

ableton-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/push_notes.py, tests/test_push_notes.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ableton Live via MCP

Claude drives a live Ableton Set through the AbletonMCP server (jpoindexter fork v2.0.0, 128 tools, all prefixed mcp__ableton__). Limits below are for this fork.

References (read on demand):

  • references/setup-install.md — first-time install (Remote Script + server + verify)
  • references/troubleshooting.md — connection failures, tool errors
  • references/als-xml.md — reading Arrangement content from the saved .als (MCP can't)

For arrangement craft (section design, bass/drum patterns, FX chains) use the ableton-arrangement skill; this skill is the mechanics and the gotchas.

Mental model

  • Live and stateful. Every call mutates the open Set immediately. No preview/dry-run. Undo is Live's own Cmd/Ctrl-Z.
  • Single session. Controls one Ableton instance — the frontmost open Set. No diffing two Sets, no background operation. Two clients on one Live collide; work sequentially.
  • No autosave. Claude can't save/open/new a Set — the USER Cmd-S's. After a Set switch, the server re-attaches to the new frontmost Set.
  • Deferred tools (Claude Code). Load schemas before first use: ToolSearch select:mcp__ableton__<name>.
  • Reason in BARS, never seconds. Sizes and positions are bar counts; convert everything to bars up front.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
