The Problem of Missing Visuals in Design Reviews
Today, when you're building out a new page layout, you hit those spots that need an image—a hero banner, a feature block, user avatars. What do you do? You stop coding or designing and switch tabs to find a filler asset. Then you manually adjust the size, change colors in a separate tool, and copy-paste it into your mockups.
With this MCP, that manual dance disappears. Just tell your agent what visual space needs filling—say, 'I need a 16:9 banner with blue backgrounds.' You get the exact URL immediately. Your AI acts as an instant asset library, keeping you right where you need to be.
DummyImage MCP Delivers Visual Assets Through `generate_image`
You no longer have to stop and search for external placeholder services or spend time manually creating colored boxes in your design software. You simply prompt the agent, giving it parameters like dimensions and hex codes.
The result is a fully formed URL ready to be used—whether you're dropping it into code or sharing it with a PM. It cuts out every step of asset sourcing.
What your AI can actually do with this
Stop wasting time looking up placeholder image services or manually creating empty colored boxes in Figma. With this MCP, you talk to your agent and it handles the visual assets. You can tell it to generate a specific size—like 16:9 for a hero banner—and specify colors that match your brand hex codes.
Need custom text on the image? Just ask. The tool even lets you pick formats like PNG or GIF, making sure the asset is ready for deployment right away. It’s basically an instant way to visualize content blocks and test layouts without ever having to load a real picture. When you connect this MCP through Vinkius, your agent becomes a powerful visual assistant built directly into your existing workflow.
019e5d13-a17f-71a4-acf7-518d32c9ba05 Here's how it actually works
The bottom line is: you tell your AI what visual asset you need, and it gives you the working link immediately.
Subscribe to this MCP and set the token field to 'PUBLIC'.
Start talking to your agent in any compatible client (Claude, Cursor, etc.).
Ask it to generate a placeholder image URL with specific parameters like size or color.
Who is this actually for?
Anyone who has to move between writing requirements, designing mockups, and coding layouts. This is for people tired of context switching just because they need a picture that isn't there yet.
Generates specific placeholders for wireframes or component libraries without leaving the design tool workflow.
Fills layout gaps with correctly sized, colored image URLs during frontend development and testing phases.
Visualizes content block placements or banner requirements for stakeholders when gathering initial project scope.
What Changes When You Connect
Stop searching for placeholder sites. Your agent generates the URL directly, so you never lose momentum between writing and designing.
Test responsive designs accurately by setting specific aspect ratios (like 16:9) right in your prompt. You know exactly how that banner will look.
Match brand guidelines instantly. Specify hex colors for both the background and foreground text to ensure visual consistency from day one.
The workflow is faster than copy-pasting assets. Your agent handles size, color, format selection (PNG/JPG), and generation in a single turn.
Perfect for requirement gathering. Product Managers can visualize content blocks and banner placements using specific dimensions before writing any code.
See it in action
Building a Landing Page Wireframe
A developer needs to mock up a three-column feature section. Instead of manually resizing images, they prompt their agent: 'Generate three 300x250 placeholder images with blue backgrounds.' The agent runs generate_image and provides the three needed URLs instantly for testing.
Mocking Up a Hero Banner
A designer needs a prominent banner that must be 16:9, use the brand's specific #0033CC color, and include the text 'Welcome'. They prompt their agent with those details, getting the exact PNG URL to drop into the mockups.
Testing a Profile Component
A developer is building a user dashboard. The component requires small 100x100 profile pictures in JPG format. They ask their agent for that specific placeholder, getting the correct URL without any manual steps.
Validating Content Blocks
A product manager is presenting a new flow. To show where testimonial images go, they prompt: 'Show me five 400x200 placeholders with white text saying Testimonial.' This immediately visualizes the content structure for stakeholders.
The honest tradeoffs
Using generic image links
Copying a placeholder URL that doesn't match the required size or format, leading to broken layouts and wasted time fixing assets.
Use generate_image through your agent. Specify all parameters—size (e.g., 800x450), color, and format (PNG)—in one prompt so you get a guaranteed working URL.
Manually creating empty boxes
In the design tool, drawing solid colored rectangles to represent where an image should go. This is time-consuming and doesn't help with responsive testing.
Let your agent generate the asset using generate_image. It handles the visual representation and provides a real URL you can use immediately in your code or mockups.
Forgetting to specify text
Generating an image for a banner but forgetting to add the required title or headline, making the placeholder useless during review.
Always include text details when running generate_image. Ask your agent to 'Generate a 1200x300 image with white text saying [Headline]' to ensure all necessary content is visible.
When It Fits, When It Doesn't
Use this MCP if you need quick, customizable URLs for visual assets—anything from profile icons to complex banner mockups. The key here is that the output must be a usable link and you need control over dimensions, colors, and text overlay. Don't use it if you require actual, unique photography or illustrations; this tool only generates placeholders. If your goal is pure content generation (like writing copy), then stick to a general-purpose text agent instead.
Questions you might have
How do I use DummyImage MCP to generate a specific size image? +
You pass the dimensions directly in your prompt using generate_image. For example, asking for 'a 600x400 placeholder' will give you the correct URL immediately.
Can DummyImage MCP handle multiple image formats? +
Yes. You can request different formats like PNG or JPG by including the format in your prompt when using generate_image. This keeps your assets ready for various platforms.
What if I want to add text using DummyImage MCP? +
You specify the required text and its color directly in your request. The agent will use generate_image to overlay custom labels onto the placeholder, ensuring your headlines are visible.
Do I need a special key for DummyImage MCP? +
No. Since this is a public utility, you enter 'PUBLIC' in the token field when connecting the MCP to your agent client.
How does the generate_image tool handle defining aspect ratios? +
The generate_image tool accepts specific aspect ratio definitions, like 16:9. This lets you test how your content looks in responsive containers without needing to calculate exact dimensions.
Can I use the generate_image tool to control image colors? +
Yes, you can specify hex codes for both background and foreground colors. This ensures your generated mockups match your project's brand guidelines perfectly.
Does generate_image support standard size keywords besides specific pixel dimensions? +
Absolutely. In addition to providing exact measurements (e.g., 300x250), you can use common keywords like 'hd1080' or 'medrect' for quick, industry-standard placeholder sizes.
What is the best way to integrate generate_image into a development workflow? +
You should run the tool directly through your AI client. It generates image URLs you can immediately embed into your front end, cutting out the need for external placeholder services.
Can I specify custom text to appear on the generated image? +
Yes! Use the text parameter in the generate_image tool to define any string you want to display in the center of the placeholder.
What image formats are supported by the generator? +
The generate_image tool supports gif, jpg, jpeg, and png formats. You can specify your preference using the format parameter.
Do I need to include the '#' symbol for hex colors? +
