Set properties on an arrangement clip. Parameters: - track_index: Track number (1-based). - clip_index: Clip position (1-based). - clip_name: Clip name (alternative to clip_index). - name: New clip name. - muted: Mute state. - color: Color (0x00RRGGBB). - looping: Loop on/off. - loop_start: Loop ...
AI agents use set_arrangement_clip_property 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 modifies clip metadata and settings (name, mute, color, loop points, gain, pitch) but does not create, delete, or execute arbitrary code. All changes are reversible through subsequent property modifications. While it affects the audio production workflow, the blast radius is limited to individual clip parameter changes within a loaded Ableton Live session.
From the tool's definition Tool description states 'Set properties on an arrangement clip' with parameters that modify clip attributes including name, muted state, color, looping behavior, gain, pitch, and warping settings.
Documented attack patterns abuse exactly the kind of access set_arrangement_clip_property 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 set_arrangement_clip_property:
{
"version": "1",
"default": "deny",
"tools": {
"set_arrangement_clip_property": {
"limits": [
{
"counter": "set_arrangement_clip_property_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_arrangement_clip_property 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.

Set properties on an arrangement clip. Parameters: - track_index: Track number (1-based). - clip_index: Clip position (1-based). - clip_name: Clip name (alternative to clip_index). - name: New clip name. - muted: Mute state. - color: Color (0x00RRGGBB). - looping: Loop on/off. - loop_start: Loop start in beats. - loop_end: Loop end in beats. - gain: Audio gain (0.0-1.0). - pitch_coarse: Semitone pitch shift (-48 to 48). - pitch_fine: Fine pitch shift (-50 to 49 cents). - warping: Warp on/off. - warp_mode: Warp mode (0-6). 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 set_arrangement_clip_property: 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.
set_arrangement_clip_property 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 set_arrangement_clip_property 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 set_arrangement_clip_property. 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.
set_arrangement_clip_property 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.
