Category Design and Media
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 0 of 33 dependencies flagged as unhealthy. View diagnostics → Pass
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to wstierhout/ableton-live-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 48 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability87
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 14608 tokens (~93/item across 156 items; 156 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage77
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 20% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 8 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 157 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
tap_tempo ~41
Tap the tempo once. Tapping repeatedly at a beat sets the tempo to that rate; a single tap nudges the transport. Returns the resulting tempo.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
transform_clip ~258
Read a MIDI clip's notes, apply a classical motif transformation, and write the result. Overwrites the source clip unless ``dest_clip_index`` is given (in which case that destination slot is REPLACED instead). op (one of): transpose - shift every pitch by ``amount`` semitones (integer; may be negative). Timing unchanged; out-of-range pitches clamped. invert - mirror pitches about the first note's pitch (up-motion becomes down-motion). ``amount`` is ignored. retrograde - play the motif backwards in time (onset order reversed, durations preserved). ``amount`` is ignored. augment - scale start times and durations by ``amount`` (a factor > 1 stretches/slows, 0 < ``amount`` < 1 compresses/speeds up). Requires ``amount`` > 0. ``amount`` therefore means semitones for transpose and a time factor for augment. Returns a short summary of what was written.

trigger_session_record ~52
Start Session recording into armed tracks; record_length in beats records a fixed-length loop (e.g. 16.0 = 4 bars) then auto-switches to playback.

undo ~74
Revert the most recent undoable Live-set action. This mutates the set and may remove newly created content or restore deleted content. It has no target parameter: Live chooses the top undo-history entry. Use redo to reapply an accidental undo. Prefer batch_commands for related edits so one undo reverts the group.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |

| result | string | yes | – |
No examples provided.
write_automation ~79
Write clip automation for a device parameter. points = [{"time": beats, "value": v}, ...]. Replaces any existing envelope for that parameter on the clip.

write_drum_grid ~210
Write drums from an ASCII grid (16th-note steps). REPLACES existing notes. grid: one line per instrument: "name: pattern" where pattern chars are 'X' (accent, vel 105), 'x' (normal, 85), 'o' (soft, 55), '.' or '-' (rest). Line length = number of 16th steps (16 = one 4/4 bar; 32 = two bars...). Instruments: kick snare rim clap chat phat ohat ltom mtom htom crash ride perc shaker, or a raw MIDI number ("36: x..."). Example (one bar of lofi): kick: X..x......X..... snare: ....x.......x... chat: x.o.x.o.x.o.x.o.
