Get information about all lights connected to the Hue bridge.
AI agents call get_all_lights to retrieve information from Philips Hue MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves data about connected lights without modifying, deleting, or executing any operations. It is a straightforward read operation that returns information only. The blast radius of misuse is minimal—an AI agent could learn about the lighting setup but cannot control, delete, or cause harm through retrieval alone.
From the tool's definition Tool name 'get_all_lights' and description 'Get information about all lights connected to the Hue bridge' indicate a retrieval operation with no side effects.
