turn_off · Switcher MCP Server MCP: Risk & Policy

WHAT IT DOES

What turn_off does on Switcher MCP Server

AI agents invoke turn_off to trigger actions in Switcher MCP Server. 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.

WHY IT NEEDS A POLICY

Why turn_off needs a policy

This tool controls a physical IoT device by turning it off, which constitutes triggering an external operation with real-world consequences (e.g., cutting power to appliances like water heaters or other connected equipment). It falls under Execute as it performs an action on an external system.

From the tool's definition Turn off a Switcher device — triggers an external physical operation on a KIS device (cutting power to a connected appliance)

Verdict

turn_off Rate-limited

turn_off 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 turn_off

What does the turn_off tool do? +

Turn off a Switcher device. It is categorised as a Execute tool in the Switcher MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on turn_off? +

Register the Switcher MCP Server MCP server in PolicyLayer and add a rule for turn_off: 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 Switcher MCP Server. Nothing to install.

What risk level is turn_off? +

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

Can I rate-limit turn_off? +

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

Set action: deny in the PolicyLayer policy for turn_off. 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 turn_off? +

turn_off is provided by the Switcher MCP Server MCP server (liebstein/switcher-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
