AI agents call delete_clip to permanently remove resources in Ableton — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a clip from Ableton Live removes audio/MIDI content that cannot be recovered through normal undo mechanisms once the session is saved. This is an irreversible action that destroys data. Although the impact is scoped to a single clip rather than an entire project, the loss is permanent and significant in a music production context.
From the tool's definition Tool name is 'delete_clip' and description states 'Delete a clip from a clip slot.' The verb 'Delete' is explicit and irreversible.
Documented attack patterns abuse exactly the kind of access delete_clip gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ableton, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_clip:
{
"version": "1",
"default": "deny",
"hide": [
"delete_clip"
]
}delete_clip disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a clip from a clip slot. It is categorised as a Destructive tool in the Ableton MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ableton MCP server in PolicyLayer and add a rule for delete_clip: 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. Nothing to install.
delete_clip is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_clip 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 delete_clip. 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.
delete_clip is provided by the Ableton MCP server (jpoindexter/ableton-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ableton, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
