Koboyo Icons

Koboyo Icons is a massive collection of more than 71,000 hand-drawn SVG icons organized into browsable categories. The icons are free to use, and the library is designed to work both as a traditional icon browser and as a resource that AI coding assistants can access directly through a Model Context Protocol integration. If you're building interfaces and want a distinctive hand-drawn aesthetic without licensing headaches, this is a substantial library to draw from.

The collection covers a wide range of visual categories. There are practical sets for commerce, agriculture, health, and technology. There are expressive sets with faces, gestures, and people. There are abstract shapes, mascots, and playful illustrations. The mascot category alone contains over 8,600 variants, and the playful set has nearly 4,800. For teams that want a cohesive hand-drawn look across an entire product, having this depth means you're less likely to run out of options mid-project.

What makes the library stand out is the AI integration angle. Koboyo exposes the icon collection through an MCP server, which means tools like Claude Desktop, Cursor, and VS Code with Codex can query and retrieve icons programmatically. You add the integration with a single command, and then your AI assistant can search the library and pull icons directly into your workflow. It's a different delivery model than downloading packs manually or searching a web catalog.

The browsing interface on the site organizes icons into top-level types like face, mark, object, people, scene, and solid, with subcategories beneath each. You can filter by subcategory, and counts are displayed so you know how deep each section goes. The tech subcategory has over 1,000 icons, food has nearly 1,300, and the hand gesture set has close to a thousand. Navigation is straightforward, though with a library this size, the MCP integration might be faster for targeted searches once you're familiar with what's available.

For designers and developers, the value is in the volume and the consistency of style. Hand-drawn icons can be hard to source at scale because individual illustrators produce limited sets. Here you get tens of thousands in a unified aesthetic, which is useful for products that want a friendly, sketch-like feel without commissioning custom work. The SVG format means the icons scale cleanly and can be styled with CSS.

The icons are free with a permissive license. There's no account required to browse or download, and the MCP integration is also free to connect. If you're working in an environment where AI tools are part of your daily coding workflow, having an icon library that speaks the same protocol as your assistant removes a small but real friction point.

One limitation is that the hand-drawn style won't fit every product. If you need crisp, geometric icons for a corporate dashboard, this isn't the set. But for apps, games, educational tools, or anything where a human touch adds warmth, it's a deep well to draw from.
