What you can do with this MCP connector
PlaceKitten handles mockup kitten images—it's what you use when your design mockups need placeholder assets but you don't wanna jump out to another site just to grab a picture. You can run this right from your code editor or chat window.
This server gives you two specific tools: get_kitten and get_grayscale_kitten. They let you get high-quality, dimension-specific placeholders without messing up your workflow. The whole point is precision; you need the image to fit exactly where it's supposed to go.
If you gotta generate a standard, full-color kitten mockup, use the get_kitten tool. This gets you a classic placeholder that shows off color fidelity and general design context. When you call this tool, you specify the exact dimensions—the width and height in pixels—that your layout demands. You tell it 'I need 400 by 300,' and it gives you exactly that size, keeping your mockups consistent.
Need something different? If your design theme calls for a specific monochrome look or if color is distracting from the core UI element, use get_grayscale_kitten. This tool generates a strictly black-and-white kitten placeholder. It’s perfect when you're building out a minimalist site concept or testing how text and structure look against a muted background.
Just like the full-color version, you call this tool and define the precise pixel dimensions—the width and height—you need for your asset slot.
You never have to guess on size. Whether you’re pulling a vibrant, full-color kitten with get_kitten or a clean, monochrome one using get_grayscale_kitten, both tools let you set custom dimensions. You control the exact pixel count for width and height in every single request. This means if your layout needs an image that's 600 pixels wide by 450 pixels tall, you specify those numbers, and you get it.
Using these two tools gives you total control over two key elements: color palette and physical size. You can grab the full-color standard through get_kitten, or you can go strictly B&W with get_grayscale_kitten. Both options let your agent specify custom dimensions, guaranteeing that the placeholder image you receive matches the pixel requirements of your design system perfectly.
It's built for developers who know exactly what they need and don't have time for guesswork. You’re dealing only in function calls: define the color—full or gray—and define the exact width/height needed. That’s it.
How PlaceKitten MCP Works
- 1 1. Connect the PlaceKitten MCP Server to your AI client via Vinkius.
- 2 2. Tell your agent what you need: Are you building a full-color mockup, or do you require black and white assets? What are the exact pixel dimensions?
- 3 3. Your agent calls either
get_kittenorget_grayscale_kitten, providing the size parameters, and returns a direct image URL.
The bottom line is that your AI client handles the API call to PlaceKitten using one of its two tools and gives you the resulting image link.
Who Is PlaceKitten MCP For?
Front-end developers need this when they're building responsive layouts and testing image containers. UI/UX designers use it for quick, high-fidelity mockups that don't rely on real assets. Prototypers need it to quickly visualize content flow without having to source or wait for placeholder images.
Tests image component responsiveness and layout dimensions using get_kitten across various screen sizes.
Creates grayscale mockups or full-color wireframes by calling get_grayscale_kitten for specific aesthetic themes.
Visualizes content flow quickly by generating multiple placeholder images of varied sizes in a chat session.
What Changes When You Connect
- Need to test a banner section? Call
get_kittenand specify the exact width and height, like 800x200. You get an immediate URL for your mockup, saving file handling time. - Building a dark mode design? Use
get_grayscale_kitten. It forces black and white placeholders so you can test the aesthetic without needing color assets. - Eliminate placeholder fatigue. Instead of using generic gray boxes, you use PlaceKitten to generate real-looking kitten images that fit your exact component size (e.g., 400x300).
- Your AI client handles the API calls. You just tell it: 'Give me a grayscale image, 500x500.' The server takes care of the rest.
- It's quick and simple. Whether you need color or black-and-white assets, calling
get_kittenorget_grayscale_kittenis a single step in your conversation.
Real-World Use Cases
Testing component resizing for mobile views
A frontend developer needs to see how an image container looks when scaled down. They ask their agent to use get_kitten with dimensions of 300x150 pixels, instantly getting a working mockup asset URL without manually adjusting any files.
Designing a minimalist landing page
A UI/UX designer is building a site that must feel clean and monochrome. They tell their agent to use get_grayscale_kitten for all main visual elements, ensuring the placeholder assets maintain the desired B&W aesthetic throughout the prototype.
Filling image gaps in an existing wireframe
A content prototyper is laying out a gallery section. They don't want to use generic boxes; they ask for several images using get_kitten with varying dimensions (e.g., 200x200, 400x300) to visualize the actual content flow.
Comparing color vs. monochrome options
A designer needs to decide if a feature should be presented in full color or B&W. They run two separate calls: one with get_kitten and another with get_grayscale_kitten, comparing the immediate outputs side-by-side.
The Tradeoffs
Using placeholders that are too generic
The developer manually types 'placeholder image' into a simple API call, receiving a boring gray box with no dimension control.
→
Don't use generic tools. To get an asset for your specific layout, you must use get_kitten or get_grayscale_kitten, specifying the exact pixel dimensions (e.g., 400x300) in your prompt.
Forgetting the color constraint
A designer needs a B&W asset for print, but only calls get_kitten, resulting in an unwanted full-color image that breaks the aesthetic.
→
If you need black and white, you must explicitly use the specialized tool: get_grayscale_kitten. This guarantees the correct color output every time.
Not controlling dimensions
The user calls a basic image retrieval function without specifying size, leading to an asset that is too large or too small for the intended component.
→
Both tools require dimension specification. Always include the desired width and height in your prompt so that the server uses get_kitten or get_grayscale_kitten with precise parameters.
When It Fits, When It Doesn't
Use PlaceKitten if you are building a design mockup, prototype, or responsive web layout and need placeholder images of specific sizes. The choice between tools depends entirely on your aesthetic needs: use get_kitten when the visual content must be full-color; use get_grayscale_kitten when the mockup requires black and white assets to test a monochrome theme.
Don't use this server if you are trying to fetch actual live data (like user records or database entries), or if your design needs complex image manipulation beyond simple color filtering. For structured data, look for specialized API connectors rather than these visual asset tools.

Available Capabilities
Mockups used to be a pain in the butt.
Before servers like this, building mockups meant downloading actual assets or relying on generic gray boxes. If you were designing an e-commerce page, finding images that fit perfectly—say, 350x220 pixels—was a multi-step process of resizing and sourcing.
Now, your agent handles it all. You just tell the system what you need (e.g., 'I need a full-color image for this banner'), and it calls `get_kitten` with the exact dimensions. The mockup asset appears instantly, ready to drop into your code.
PlaceKitten MCP Server: Generate specific assets in one step.
The process used to involve opening a separate image tool, manually changing the dimensions, and hoping the asset was the right color. Now, you keep everything contained within your chat or IDE workflow.
You control both the dimension (e.g., 500x500) and the style (color via `get_kitten` or monochrome via `get_grayscale_kitten`) in a single command. It's that simple.
Common Questions About PlaceKitten MCP
How do I use get_kitten for my mockup? +
To use it, ask your agent to 'Get a kitten image 400 pixels wide and 300 pixels high.' The server uses get_kitten to generate the full-color asset link immediately.
Is get_grayscale_kitten different from get_kitten? +
Yes, they serve different purposes. get_kitten returns color images; get_grayscale_kitten specifically enforces a black and white aesthetic, which is useful for certain design themes.
Does PlaceKitten require an API key? +
No specific key is required. Since it's a public service, you just need to tell your agent to use the available tools in the chat.
What if I change the dimensions for get_kitten? +
You simply update the numbers in your prompt (e.g., '200x150 pixels'). The server uses get_kitten and generates a new image link with those precise specs.
What happens if I pass invalid dimensions to the `get_kitten` tool? +
The server returns a structured error message detailing the input failure. This means your AI client handles it gracefully, telling you exactly which pixel value was wrong or missing.
Are there any rate limits when using the `get_grayscale_kitten` tool? +
The service is designed for high volume usage. While no strict technical limit exists on our end, excessive calls in rapid succession might trigger temporary throttling to maintain performance.
How does the AI client handle the URL output from `get_kitten`? +
Your agent receives the direct image URL. You can then pass that link straight into markdown or a web component, allowing your workflow to use the generated asset immediately.
Do I need any special setup for my AI client to access `PlaceKitten`? +
No complicated setup is needed. Since it's an MCP server, you just connect your preferred agent (like Claude or Cursor) via the Vinkius Marketplace connection point.
How do I get a kitten image with specific dimensions? +
Use the get_kitten tool and provide the desired width and height in pixels. The agent will return a URL to a kitten image matching those exact dimensions.
Can I generate black and white kitten images for my design? +
Yes! Use the get_grayscale_kitten tool. It works just like the standard tool but applies a grayscale filter to the image, perfect for minimalist or wireframe designs.
Is an API key required to use PlaceKitten? +
No, PlaceKitten is a free public service. You don't need to create an account or generate a token. Simply connect the server and start using it.
