get-lights

THE RISK

Low Risk

Why get-lights needs a policy

This tool only retrieves or queries data about Hue lights (listing all lights or fetching details about a specific light). It has no side effects and does not create, modify, delete, or execute any operations. It falls squarely within the Read category with low severity, as compromised access would only expose information about the user's lighting setup.

From the tool's definition Tool name is 'get-lights' and description states 'List all Hue lights or get details for a specific light' — both are read-only query operations that retrieve information without modifying state.

POLICY

How to control get-lights

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get-lights": {}
  }
}

get-lights is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register OpenHue 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.
