Why set_color_temperature needs a policy

This tool modifies the state of a smart home device (color temperature setting) which is a reversible write operation. It changes device configuration but does not delete data or execute arbitrary code. Misuse could cause unintended lighting changes but has limited blast radius.

POLICY

How to control set_color_temperature

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

policy.json

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

set_color_temperature 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.
