Implementation Reference
- src/tools.ts:280-299 (handler)Handler function for 'resize_image' tool in TOOL_HANDLERS, which extracts parameters and calls the core resize logic.
resize_image: async (request) => { await handleResizeImageTool( request.params.arguments as { imagePath: string; outputPath?: string; width: number; height: number; method: 'scale' | 'fit' | 'cover' | 'thumb'; }, ); return { content: [ { type: 'text', text: 'Image resized successfully', }, ], metadata: {}, }; }, - src/tools.ts:213-241 (helper)Core implementation of image resizing using Tinify API, handling input parameters, resizing, and output path generation.
async function handleResizeImageTool({ imagePath, outputPath, width, height, method, }: { imagePath: string; outputPath?: string; width: number; height: number; method?: 'scale' | 'fit' | 'cover' | 'thumb'; }) { const source = tinify.fromFile(imagePath); const resized = source.resize({ method: method || 'fit', width, height, }); let dest = outputPath; if (!dest) { const dir = path.dirname(imagePath); const basename = path.basename(imagePath, path.extname(imagePath)); const ext = path.extname(imagePath).slice(1); dest = path.join(dir, `${basename}_${width}x${height}.${ext}`); } await resized.toFile(dest); } - src/tools.ts:79-115 (schema)Tool definition including name, description, and input schema for 'resize_image'.
