WHAT IT DOES

What audio_volume does on Omarchy-MCP

AI agents invoke audio_volume to trigger actions in Omarchy-MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why audio_volume is rated High

Triggers audio system mutations via PipeWire; side effects depend on arguments.

From the tool's definition Raise, lower or toggle mute, verify PipeWire transition, restore prior state

RECOMMENDED RULE

The rule that runs audio_volume safely

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

audio_volume Rate-limited

audio_volume stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about audio_volume

What does the audio_volume tool do? +

Raise, lower or toggle mute, verify the exact expected PipeWire transition, and restore prior volume/mute state whenever the mutation is not confirmed. It is categorised as a Execute tool in the Omarchy-MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on audio_volume? +

Register the Omarchy MCP server in PolicyLayer and add a rule for audio_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 Omarchy-MCP. Nothing to install.

What risk level is audio_volume? +

audio_volume is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit audio_volume? +

Yes. Add a rate_limit block to the audio_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 audio_volume completely? +

Set action: deny in the PolicyLayer policy for audio_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 audio_volume? +

audio_volume is provided by the Omarchy MCP server (hlsitechio/Omarchy-MCP). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
