Illos skills

Animated SVG illustrations for your website or app, added by your coding agent. This repo has a free skill and the Illos MCP server, packaged for Claude Code, Cursor, Codex and any agent that reads SKILL.md folders.

Illos.dev has 158 animated illustrations in four themes (Shader, HUD, Isometric and Interface), each in light and dark. 65 are free for commercial use, with no account and no credit.

What it does

Ask your agent for a picture where a page needs one:

Add an illustration to the empty notifications screen. Use Illos Isometric illustrations for the feature sections on the home page.

The illos-library skill picks one theme for the whole site, finds the illustration that explains each section, and adds it: with one npx shadcn command in a React project, or as an SVG file anywhere else.

Install

Claude Code (the skill and the MCP server):

/plugin marketplace add navedux/illos-skills
/plugin install illos@illos-dev

Any agent, with the skills CLI (skills.sh):

npx skills add navedux/illos-skills

Cursor: open Customize, From GitHub Repository, and paste this repo's URL. Or copy skills/illos-library into .cursor/skills/.

Codex: copy skills/illos-library into .agents/skills/ in your project, or ~/.agents/skills/ for every project.

The MCP server on its own

https://illos.dev/mcp (Streamable HTTP, no sign-in) gives any MCP client three tools: find_illustrations, get_illustration and list_themes.

claude mcp add --transport http illos https://illos.dev/mcp

Cursor (~/.cursor/mcp.json):

{ "mcpServers": { "illos": { "url": "https://illos.dev/mcp" } } }

New illustrations in the same style

When the library doesn't have what a page needs, the Illos Pro skills teach your agent a theme's rules, so it can draw new illustrations that match and check each one. They come with Illos Pro.

Licence

The skill and the files in this repo: MIT. The illustrations: illos.dev/license. Free ones need no credit.
