Stop playback for a specific session clip slot. Use to halt one clip without stopping the global transport. Idempotent for already-stopped clips; returns changed=false when no launch state changed and marks async playback verification unverified.
AI agents invoke clip_stop to trigger actions in Ableton Mind. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool executes an action that controls real-time audio/music production state. While not destructive (the operation is reversible by playing the clip again) and not a data modification in the persistent sense, it triggers external effects on an audio engine's runtime behavior. The ability to stop arbitrary clips could disrupt a user's active music production session.
From the tool's definition Tool description states 'Stop playback for a specific session clip slot' and 'Use to halt one clip without stopping the global transport' — directly triggers audio playback control operations in Ableton Live.
Attacks that exploit this kind of access
Stop playback for a specific session clip slot. Use to halt one clip without stopping the global transport. Idempotent for already-stopped clips; returns changed=false when no launch state changed and marks async playback verification unverified. It is categorised as a Execute tool in the Ableton Mind MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ableton Mind MCP server in PolicyLayer and add a rule for clip_stop: 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_stop is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the clip_stop 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_stop. 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_stop 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.
