Why reconnect_service needs a policy

This tool triggers an external operation (reconnecting to the Mijia cloud service) and can optionally clear saved login credentials first. The primary action is initiating a cloud connection (Execute), with a secondary potentially destructive side effect of clearing saved login data.

POLICY

How to control reconnect_service

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 reconnect_service:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "reconnect_service": {
      "limits": [
        {
          "counter": "reconnect_service_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

reconnect_service 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.

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