Implementation Reference
- index.js:686-762 (handler)The main handler function that executes the rdms_download_image tool. Downloads the image from the provided RDMS URL using axios, converts to base64 if analyze=true (for AI vision), or saves to file if filename provided.
async downloadImage(imageUrl, filename, analyze = true) { await this.ensureLoggedIn(); try { const response = await this.client.get(imageUrl, { responseType: 'arraybuffer' }); const imageBuffer = Buffer.from(response.data); const contentType = response.headers['content-type'] || 'image/png'; const imageType = contentType.split('/')[1] || 'png'; if (analyze) { // Return image data for AI analysis const base64Image = imageBuffer.toString('base64'); return { content: [ { type: 'text', text: JSON.stringify({ success: true, imageUrl, type: imageType, size: imageBuffer.length, message: `Image downloaded successfully (${Math.round(imageBuffer.length / 1024)}KB)` }) }, { type: 'image', data: base64Image, mimeType: contentType } ] }; } else { // Save to file if filename provided if (filename) { const filepath = path.resolve(filename); fs.writeFileSync(filepath, imageBuffer); return { content: [{ type: 'text', text: JSON.stringify({ success: true, imageUrl, savedTo: filepath, type: imageType, size: imageBuffer.length, message: `Image saved to ${filepath}` }) }] }; } else { return { content: [{ type: 'text', text: JSON.stringify({ success: true, imageUrl, type: imageType, size: imageBuffer.length, message: 'Image downloaded successfully' }) }] }; } } } catch (error) { return { content: [{ type: 'text', text: JSON.stringify({ success: false, error: error.message, imageUrl }) }] }; } } - index.js:123-135 (schema)Input schema definition for the rdms_download_image tool, specifying parameters: imageUrl (required), filename (optional), analyze (default true).
