Implementation Reference
- src/index.ts:232-265 (handler)The handler for the 'convert_format' tool. It processes the input arguments, creates the output directory if needed, uses Sharp to convert the image to the specified format with optional quality, saves it, and returns a success message.
case 'convert_format': { const { inputPath, outputPath, format, quality = 80 } = args; await fs.mkdir(path.dirname(outputPath), { recursive: true }); let pipeline = sharp(inputPath); switch (format) { case 'jpeg': case 'jpg': pipeline = pipeline.jpeg({ quality, progressive: true }); break; case 'png': pipeline = pipeline.png({ quality }); break; case 'webp': pipeline = pipeline.webp({ quality }); break; case 'avif': pipeline = pipeline.avif({ quality }); break; } await pipeline.toFile(outputPath); return { content: [ { type: 'text', text: `Image converted to ${format} format. Saved to: ${outputPath}` } ] }; } - src/index.ts:56-75 (schema)Input schema definition for the 'convert_format' tool, specifying parameters like inputPath, outputPath, format (enum), and optional quality.
