Create a cue point at a position. Parameters: - bar: Bar number (1-based). - beat: Beat position (0-based). - name: Name for the cue point.
AI agents use create_cue_point 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 a reversible, non-destructive metadata element (a cue point/marker) within an Ableton Live project. It does not delete data, execute arbitrary code, move money, or trigger external operations with unpredictable side effects. The parameters (bar, beat, name) are simple positional and naming inputs with no capability for code execution or data destruction.
From the tool's definition Tool name 'create_cue_point' and description 'Create a cue point at a position' indicates the tool creates a new marker/reference point in the Ableton Live session.
Documented attack patterns abuse exactly the kind of access create_cue_point 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_cue_point:
{
"version": "1",
"default": "deny",
"tools": {
"create_cue_point": {
"limits": [
{
"counter": "create_cue_point_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_cue_point 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 cue point at a position. Parameters: - bar: Bar number (1-based). - beat: Beat position (0-based). - name: Name for the cue point. 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_cue_point: 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_cue_point 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_cue_point 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_cue_point. 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_cue_point 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.
