Duplicates the notes in the specified region to the destination_time. Only notes of the specified pitch are duplicated if pitch is not -1. If the transposition_amount is not 0, the notes in the region will be transposed by the transposition_amount of semitones. Raises an error on audio clips..
AI agents call duplicate_clip_region to retrieve information from Ableton Copilot MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though duplicate_clip_region only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Duplicates the notes in the specified region to the destination_time. Only notes of the specified pitch are duplicated if pitch is not -1. If the transposition_amount is not 0, the notes in the region will be transposed by the transposition_amount of semitones. Raises an error on audio clips. It is categorised as a Read tool in the Ableton Copilot MCP MCP Server, which means it retrieves data without modifying state.
Register the Ableton Copilot MCP server in PolicyLayer and add a rule for duplicate_clip_region: 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 Copilot MCP. Nothing to install.
duplicate_clip_region is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the duplicate_clip_region 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_region. 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_region is provided by the Ableton Copilot MCP server (xiaolaa2/ableton-copilot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
