WHAT IT DOES

What set_volume does on Iconnect

AI agents invoke set_volume to trigger actions in Iconnect. 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 set_volume is rated High

This tool triggers an external system operation (changing audio output volume or mute state) on the host OS. It doesn't read data, write persistent data, or destroy anything, but it does execute a system-level action. Misuse could disrupt audio output but has minimal blast radius.

From the tool's definition Set the system output volume (0-100) and/or mute state

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs set_volume safely

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

set_volume Rate-limited

set_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.

The button opens the PolicyLayer dashboard: create your workspace, connect Iconnect, apply this rule, and every set_volume call is checked against it from then on.

FAQ

Questions about set_volume

What does the set_volume tool do? +

Set the system output volume (0-100) and/or mute state. It is categorised as a Execute tool in the Iconnect MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on set_volume? +

Register the Iconnect MCP server in PolicyLayer and add a rule for 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 Iconnect. Nothing to install.

What risk level is set_volume? +

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

Can I rate-limit set_volume? +

Yes. Add a rate_limit block to the 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 set_volume completely? +

Set action: deny in the PolicyLayer policy for 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 set_volume? +

set_volume is provided by the Iconnect MCP server (iconnect-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
