Add MIDI notes to an existing session clip using ADR-0003 note fields. Use after creating or locating the target clip. NOT idempotent: repeated calls append notes; returns added count and verification diff if the count does not match.
AI agents use clip_add_notes to create or update resources in Ableton Mind — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ableton Mind environment.
This tool creates new MIDI data in an audio production session. While the additions are technically reversible through undo or deletion, the tool itself performs a Write operation by creating and persisting data structures. It does not delete, execute arbitrary code, or move financial resources.
From the tool's definition Tool description explicitly states it 'Add[s] MIDI notes' and 'repeated calls append notes', indicating irreversible data creation. The note about non-idempotency and returning 'added count' confirms write semantics rather than read-only behavior.
Attacks that exploit this kind of access
Add MIDI notes to an existing session clip using ADR-0003 note fields. Use after creating or locating the target clip. NOT idempotent: repeated calls append notes; returns added count and verification diff if the count does not match. It is categorised as a Write tool in the Ableton Mind MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ableton Mind MCP server in PolicyLayer and add a rule for clip_add_notes: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ableton Mind. Nothing to install.
clip_add_notes is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the clip_add_notes rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for clip_add_notes. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
clip_add_notes is provided by the Ableton Mind MCP server (ableton-mind). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
clip_add_notes is one line of Ableton Mind's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
