Load a drum rack and then load a specific drum kit into it. Parameters: - track_index: Track number (1-based). - rack_uri: The URI of the drum rack to load (e.g., 'Drums/Drum Rack'). - kit_path: Path to the drum kit inside the browser (e.g., 'drums/acoustic/kit1').
AI agents use load_drum_kit to create or update resources in Ableton MCP Extended — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ableton MCP Extended environment.
This tool creates/modifies content in Ableton Live by loading a drum rack and kit onto a track. It is reversible (the rack/kit can be removed or replaced), placing it in the Write category rather than Execute or Destructive. Misuse could disrupt a session's track layout but is not irreversible.

Documented attack patterns abuse exactly the kind of access load_drum_kit gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ableton MCP Extended, and nothing reaches the server without passing your rules. This is the rule we recommend for load_drum_kit:
{
"version": "1",
"default": "deny",
"tools": {
"load_drum_kit": {
"limits": [
{
"counter": "load_drum_kit_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}load_drum_kit stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Load a drum rack and then load a specific drum kit into it. Parameters: - track_index: Track number (1-based). - rack_uri: The URI of the drum rack to load (e.g., 'Drums/Drum Rack'). - kit_path: Path to the drum kit inside the browser (e.g., 'drums/acoustic/kit1'). It is categorised as a Write tool in the Ableton MCP Extended MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ableton MCP Extended MCP server in PolicyLayer and add a rule for load_drum_kit: 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 MCP Extended. Nothing to install.
load_drum_kit 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 load_drum_kit 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 load_drum_kit. 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.
load_drum_kit is provided by the Ableton MCP Extended MCP server (uisato/ableton-mcp-extended). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
