Implementation Reference
- src/tools/select-image.ts:48-78 (handler)The implementation of the 'select_image' tool handler, which processes input parameters, calls the Open Food Facts API via 'offPost', and returns the result.
async (args) => { const body: Record<string, string> = { code: args.barcode, imgid: String(args.imgid), id: `${args.imagefield}_${args.lc}`, }; if (args.angle) { body.angle = args.angle; } if (args.x1 !== undefined) { body.x1 = String(args.x1); } if (args.y1 !== undefined) { body.y1 = String(args.y1); } if (args.x2 !== undefined) { body.x2 = String(args.x2); } if (args.y2 !== undefined) { body.y2 = String(args.y2); } const data = await offPost(config, '/cgi/product_image_crop.pl', body); return jsonResult(data as Record<string, unknown>); }, - src/tools/select-image.ts:8-35 (schema)The input schema definition for the 'select_image' tool, including validation and field descriptions.
