Move a device one position to the right in the device chain.
AI agents use move_device_right to create or update resources in Ableton — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ableton environment.
This tool modifies the arrangement of devices within Ableton Live's signal chain, which changes the session state but is fully reversible (the device can be moved left again). This qualifies as Write rather than Execute because it performs a structural reordering operation rather than triggering computational effects.
From the tool's definition Tool name 'move_device_right' and description 'Move a device one position to the right in the device chain' indicates modification of the device chain configuration within an Ableton Live session.
Documented attack patterns abuse exactly the kind of access move_device_right 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 move_device_right:
{
"version": "1",
"default": "deny",
"tools": {
"move_device_right": {
"limits": [
{
"counter": "move_device_right_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}move_device_right 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.
Free to start. No card required.
Move a device one position to the right in the device chain. It is categorised as a Write tool in the Ableton MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ableton MCP server in PolicyLayer and add a rule for move_device_right: 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.
move_device_right 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 move_device_right 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 move_device_right. 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.
move_device_right 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.
