# Crop Coord Maximizer MCP for AI Agents MCP > Crop Coord Maximizer calculates the exact pixel coordinates needed to crop any image for a specific aspect ratio, like 16:9 or 9:16. It ensures your primary subject remains centered and visible in the cropped frame, saving you time and preventing wasted visual space. ## Overview - **Category:** automation - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_dFbsQkwvj5otDjB7EDaLemQhY8CtXY3FdNWYW489/mcp - **Tags:** cropping, aspect-ratio, pixel-perfect, image-editing, coordinates ## Description This MCP lets content creators stop guessing where their subjects are when resizing images. Instead of manually cropping and hoping the main focus stays put, you feed the system a source image and tell it what ratio you need—whether that's for Instagram Stories or YouTube thumbnails. It calculates precise top-left and bottom-right coordinates that guarantee your focal point stays centered within the new frame. You can also check if different ratios are standard formats and review the metadata to understand how much area reduction is involved. By connecting this MCP via Vinkius, your AI client handles all the complex geometry calculations instantly. It’s essential for anyone who needs reliable, pixel-perfect cropping coordinates without the guesswork. ## Tools ### calculate_crop Calculates the precise top-left and bottom-right pixel coordinates required to crop an image based on a defined aspect ratio while centering a specific subject point. ## Prompt Examples **Prompt:** ``` I need a 16:9 crop for this photo. The main focus is near the bottom left corner. ``` **Response:** ``` **Crop Calculation Results** Based on your image (3840x2160) and target ratio (16:9), here are the optimal coordinates: * **Top-Left:** (480, 0) * **Bottom-Right:** (3840, 2160) The resulting dimensions are 3360x2160 pixels. The algorithm prioritized keeping your subject visible while adhering to the required format. ``` **Prompt:** ``` Is a ratio of 0.5625 standard for mobile? What does it mean? ``` **Response:** ``` **Aspect Ratio Validation** Yes, the ratio 0.5625 matches the standard 'portrait_mobile' format (9:16). This is commonly used for social media stories. * **Standard:** Portrait Mobile (9:16) * **Compatibility:** High This means you can confidently use this ratio without worrying about falling outside common platform guidelines. ``` **Prompt:** ``` Check the metadata if I crop a 1920x1080 image down to 1080x1920. ``` **Response:** ``` **Crop Metadata Report** Analyzing Source: 1920 x 1080 Target Crop: 1080 x 1920 * **Scale Factor:** 0.5625 * **Area Preservation:** Approximately 56.25% of the original area. This indicates a significant dimensional shift, which is important to know when planning your final layout. ``` ## Capabilities ### Determine precise crop coordinates Calculate exact top-left and bottom-right pixel points to fit any specified aspect ratio (e.g., 1:1 or 9:16). ### Validate image ratios Check if a given numeric ratio matches common industry standards like 'portrait_mobile' or 'landscape'. ### Review crop metadata Get data about the scale factor and percentage of area preserved when executing a crop. ## Use Cases ### Adapting gallery shots for Instagram Stories A client has a beautiful 4000x3000 photo. They ask their agent to calculate the coordinates needed to crop it to 9:16, making sure the model's face stays centered and doesn't get cut off. ### Creating video thumbnails for YouTube A content creator needs a thumbnail (16:9) from a vertically shot image. The agent uses the MCP to calculate the best crop, maximizing visibility while keeping the main action in the center of the frame. ### Preparing print materials with specific ratios A designer needs to make several assets for different print sizes (e.g., 2:3 vs 1:1). They use the MCP to validate these required aspect ratios against industry standards before starting any work. ### Batch resizing a photoshoot portfolio A photographer needs coordinates for 50 different images. The agent runs through the `calculate_crop` tool repeatedly, generating a manifest of optimal crop points for each image to maintain subject focus across all outputs. ## Benefits - Stop guessing where your subject is. Use the core function to calculate coordinates that guarantee your focal point stays centered, no matter the aspect ratio. - Maintain brand consistency across platforms. Get guaranteed pixel-perfect dimensions for YouTube (16:9), Instagram (4:5), and Stories (9:16) from one source image. - Understand your output instantly. The MCP provides metadata detailing the scale factor and exactly how much of the original area you are preserving in the new crop. - Validate complex formats quickly. Check if a random ratio you need is actually a recognized industry standard using the validator tool. - Saves time on tedious adjustments. You eliminate hours spent manually adjusting crops and checking aspect ratios across hundreds of images. ## How It Works The bottom line is, it gives you exact numerical instructions for cropping so your visuals look right every single time. 1. You upload your source image and specify both the target aspect ratio (e.g., 16:9) and the location of your key subject within that image. 2. The MCP processes this information, running an algorithm to find coordinates that crop the image while minimizing the shift of your specified focal point toward the center. 3. You get a set of precise pixel coordinates (top-left/bottom-right) and metadata confirming the resulting dimensions and area preservation. ## Frequently Asked Questions **How does Crop Coord Maximizer help me keep my subject centered?** The MCP calculates the ideal crop boundaries while making sure your primary focal point remains as close to the center of the new image as possible. This prevents important elements from getting cut off, ensuring a professional look every time. **Can I use Crop Coord Maximizer for different social media sizes?** Yes. You can specify any common ratio—like 1:1 for Instagram posts or 9:16 for Stories—and the MCP will calculate the coordinates needed to adapt your image perfectly for that platform. **What information does Crop Coord Maximizer give me about area loss?** It provides metadata detailing the scale factor and the exact percentage of the original source area you are keeping in the final crop. This is vital for knowing if a drastic resize will compromise your visual integrity. **Is this better than just using an online photo editor?** This MCP calculates coordinates mathematically, giving you precise pixel values and metadata reports that generic editors don't offer. It solves the complex geometry problem reliably, especially when adapting for multiple ratios. **Does Crop Coord Maximizer work with all kinds of photos?** Yes, it handles any source image you provide. Just tell your agent what ratio you need and where your key subject is located within the photo, and it does the rest.
