THE RISK

Medium Risk

Why sonos_set_volume needs a policy

This tool modifies a device setting (volume) which is a reversible write operation. It can affect an entire group of devices, giving it a moderate blast radius — e.g., setting volume to 0 or 100 unexpectedly. No data is deleted and no code is executed, so Write is the appropriate category.

From the tool's definition Set volume level on a Sonos device. Range: 0 (silent) to 100 (maximum). Affects entire group if device is grouped.

POLICY

How to control sonos_set_volume

PolicyLayer is an MCP gateway — it sits between your AI agents and Sonos Ts, and nothing reaches the server without passing your rules. This is the rule we recommend for sonos_set_volume:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sonos_set_volume": {
      "limits": [
        {
          "counter": "sonos_set_volume_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

sonos_set_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.

Create a free account and register Sonos Ts — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What does the sonos_set_volume tool do? +

Set volume level on a Sonos device. Range: 0 (silent) to 100 (maximum). Affects entire group if device is grouped. It is categorised as a Write tool in the Sonos Ts MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on sonos_set_volume? +

Register the Sonos Ts MCP server in PolicyLayer and add a rule for sonos_set_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 Sonos Ts. Nothing to install.

What risk level is sonos_set_volume? +

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

Can I rate-limit sonos_set_volume? +

Yes. Add a rate_limit block to the sonos_set_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 sonos_set_volume completely? +

Set action: deny in the PolicyLayer policy for sonos_set_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 sonos_set_volume? +

sonos_set_volume is provided by the Sonos Ts MCP server (tommertom/sonos-ts-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Sonos Ts tool call.

Start from Sonos Ts, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
