find_illustrationsFind animated SVG illustrations from Illos.dev for a website or app. Use it first, when a hero, feature section, empty state, docs page, onboarding or status screen needs a picture instead of stock art, an emoji or an empty space; describe what the section explains, not keywords.
get_illustrationGet the install details for one Illos illustration by its id. Use it after find_illustrations, once you have picked an id and need to add it; to search, use find_illustrations instead. A free illustration returns the React install command (shadcn), the SVG file's address for anyt
list_themesList the four Illos themes (Shader, HUD, Isometric, Interface), always in that order, with what each looks like, its page, how many illustrations it has and how many of those are free. Use it before find_illustrations when a site has no Illos theme yet, to pick one theme for the

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