WHAT IT DOES

What set_master_volume does on Livepilot

AI agents use set_master_volume to create or update resources in Livepilot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Livepilot environment.

RISK

Why set_master_volume is rated Medium

This tool modifies the master volume parameter of an Ableton Live project, which is a write operation—it changes data reversibly without executing arbitrary code or causing irreversible deletion. An AI agent misusing this could produce unintended loudness changes affecting the mix, but the effect is easily undone, warranting medium severity rather than high.

From the tool's definition Tool name 'set_master_volume' and description 'Set the master track volume' indicate modification of an audio parameter in Ableton Live. This creates a reversible change to project state (volume can be adjusted back).

RECOMMENDED RULE

The rule that runs set_master_volume safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Livepilot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_master_volume, this is the rule to start with:

set_master_volume Rate-limited

set_master_volume 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.

Questions about set_master_volume

What does the set_master_volume tool do? +

Set the master track volume (0.0-1.0). It is categorised as a Write tool in the Livepilot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_master_volume? +

Register the Livepilot MCP server in PolicyLayer and add a rule for set_master_volume: 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 Livepilot. Nothing to install.

What risk level is set_master_volume? +

set_master_volume is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_master_volume? +

Yes. Add a rate_limit block to the set_master_volume 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.

How do I block set_master_volume completely? +

Set action: deny in the PolicyLayer policy for set_master_volume. 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.

What MCP server provides set_master_volume? +
