Copy a session clip to the arrangement. Parameters: - track_index: Track number (1-based). - clip_index: Session clip slot (1-based). - destination_bar: Destination bar (1-based). - destination_beat: Destination beat.
AI agents use duplicate_clip_to_arrangement 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/duplicates clip data in a reversible manner—a new arrangement clip is added but the original session clip remains intact and the operation can be undone. This is a Write operation (create/modify data) rather than Destructive (irreversible deletion).
From the tool's definition Tool description: 'Copy a session clip to the arrangement.' The parameters enable programmatic manipulation of DAW state (track_index, clip_index, destination_bar, destination_beat) to create a new clip in the arrangement, modifying project state.

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 duplicate_clip_to_arrangement:
{
"version": "1",
"default": "deny",
"tools": {
"duplicate_clip_to_arrangement": {
"limits": [
{
"counter": "duplicate_clip_to_arrangement_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}duplicate_clip_to_arrangement 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.

Register the Ableton MCP Extended MCP server in PolicyLayer and add a rule for duplicate_clip_to_arrangement: 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.
duplicate_clip_to_arrangement 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 duplicate_clip_to_arrangement 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 duplicate_clip_to_arrangement. 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.
duplicate_clip_to_arrangement 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.
