Flatten a frozen track (convert freeze to permanent audio).
AI agents call flatten_track 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.
Flattening a frozen track is an irreversible operation — it permanently replaces the original MIDI/instrument track with rendered audio, destroying the original instrument chain, MIDI data, and plugin settings. This cannot be undone once committed, making it Destructive.

Documented attack patterns abuse exactly the kind of access flatten_track 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 flatten_track:
{
"version": "1",
"default": "deny",
"hide": [
"flatten_track"
]
}flatten_track disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Flatten a frozen track (convert freeze to permanent audio). 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 flatten_track: 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.
flatten_track 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 flatten_track 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 flatten_track. 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.
flatten_track 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.
