Implementation Reference
- src/index.ts:331-353 (handler)The execution logic for the toggle_power tool. It extracts parameters from args, constructs a request body with optional duration, calls the LIFX API toggle endpoint via makeLIFXRequest, and returns a success message with the API response.
case "toggle_power": { const { token, selector = "all", duration } = args as { token: string; selector?: string; duration?: number; }; const body = duration !== undefined ? { duration } : {}; const result = await makeLIFXRequest(`/lights/${selector}/toggle`, { method: "POST", body, token, }); return { content: [ { type: "text", text: `Power toggled successfully for selector "${selector}". ${JSON.stringify(result, null, 2)}`, }, ], }; } - src/index.ts:172-184 (schema)The tool definition including name, description, and input schema registered in the ListTools response.
