Ableton MCP Server

quit_ableton

Save the current Live Set when requested, then schedule Ableton Live to close after a short UI delay.

Instructions

Save the Live Set (when requested) then schedule Application.quit after a small UI delay.

Side effects: invokes Song.save() and schedules Application.quit. Example: quit_ableton(quit_delay_ticks=5) waits five UI ticks. Edge cases: missing APIs return a structured GUI workflow refusal.

TDQS

B3.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden and does well: it explicitly names the side effects (Song.save(), scheduling Application.quit), the UI-tick delay, and the edge-case behavior of a structured GUI workflow refusal. It stops short of stating irreversibility or what happens to unsaved changes when force_without_save is used.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The main action is front-loaded, and the labeled sections (Side effects/Example/Edge cases) make it scannable. Minor redundancy: 'Application.quit' is stated in both the opening sentence and the side-effects line.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with no annotations and no output schema, the description covers side effects and failure modes but leaves force_without_save semantics and the destructiveness of discarding unsaved work unexplained. Adequate but with real gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must compensate. It conveys the meaning of quit_delay_ticks ('five UI ticks') and implies the save toggle ('when requested'), but force_without_save is never mentioned and no defaults or interactions are explained, leaving one of three parameters fully undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (quit) and resource (Ableton Live), and adds a meaningful nuance: it saves first, then schedules the quit after a UI delay. It is the only quit tool among the siblings, so it is distinguishable, though it never explicitly positions itself against save_set.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The example shows how to call it but gives no when-to-use guidance, no when-not-to-use, and no alternatives. With save_set present as a sibling, the description should clarify how quit-with-save differs from simply saving, but does not.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
