Get all locators/cue points in the arrangement.
AI agents call get_locators to retrieve information from Ableton without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing locators/cue points from an Ableton Live session without creating, modifying, deleting, or executing any operations. It has no side effects and simply returns data about markers in the arrangement. Misuse by an AI agent would have minimal blast radius—at worst, it returns information about the session structure.
From the tool's definition The tool name 'get_locators' and description 'Get all locators/cue points in the arrangement' indicate a retrieval operation with no modification or side effects. The verb 'Get' explicitly denotes a read operation.
Documented attack patterns abuse exactly the kind of access get_locators gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ableton, and nothing reaches the server without passing your rules. This is the rule we recommend for get_locators:
{
"version": "1",
"default": "deny",
"tools": {
"get_locators": {}
}
}get_locators is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get all locators/cue points in the arrangement. It is categorised as a Read tool in the Ableton MCP Server, which means it retrieves data without modifying state.
Register the Ableton MCP server in PolicyLayer and add a rule for get_locators: 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. Nothing to install.
get_locators 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 get_locators 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 get_locators. 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.
get_locators is provided by the Ableton MCP server (jpoindexter/ableton-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ableton, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
