Create a new MIDI clip in the specified track and clip slot. Parameters: - track_index: Track number (1-based). - clip_index: Clip slot number (1-based). - length: The length of the clip in beats (default: 4.0).
AI agents use create_clip 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 new data (a MIDI clip) in Ableton Live but does not execute arbitrary code, delete data irreversibly, or move funds. The action is fully reversible — clips can be undone or deleted later. It falls squarely into the Write category as a content-creation operation with minimal blast radius.
From the tool's definition Tool description states 'Create a new MIDI clip' — the verb 'create' and the action of adding a new clip to a track represents data creation. The parameters allow specifying track, slot, and length, enabling reversible creation of a musical clip.
Documented attack patterns abuse exactly the kind of access create_clip 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 create_clip:
{
"version": "1",
"default": "deny",
"tools": {
"create_clip": {
"limits": [
{
"counter": "create_clip_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_clip 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.

Create a new MIDI clip in the specified track and clip slot. Parameters: - track_index: Track number (1-based). - clip_index: Clip slot number (1-based). - length: The length of the clip in beats (default: 4.0). 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 create_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 MCP Extended. Nothing to install.
create_clip 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 create_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 create_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.
create_clip 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.
