```tsx
import { Agent, ContextWindow, VectorDatabase } from "@iconmind/react";
<Agent />
<ContextWindow variant="duotone" weight="bold" />
<VectorDatabase size={32} className="text-violet-500" />
```
**5,287 icons · 31,722 drawings · 10 packages · one generated source of truth.**
Every icon is a declaration compiled into six cells by a validator that refuses geometry
it cannot draw correctly, and a nightly job rasterises all 31,722 of them and fails if any
two icons render the same. That is how a set this size still reads as one hand, and why
an assistant can be handed [an MCP server](https://iconmind.dev/docs/mcp/) that returns
real names instead of `<AgentBrain />`.
Icons get redrawn when that scan or the contact sheet catches them — a whole round of
rooms and appliances went back on the board because shapes were fusing at 16 px — and
Bluetooth was dropped because its rune needs three stroke crossings where the set allows two.
[Everything else that was turned away](https://iconmind.dev/not-here/) is written down too.
## Why this exists
Build a UI for an agent, a RAG pipeline, or an MCP server and you run out of icons
almost immediately. There is no `context-window`, no `reranker`, no `tool-calling`, no
`mcp-resource` in any mainstream set, so interfaces reach for a generic robot, a generic
database, a generic lightning bolt, and the meaning is lost.
Lucide, Heroicons and Phosphor are excellent, and a thousand domain-specific AI icons
would be scope creep for any of them. **IconMind sits next to them, not instead of
them.** The 24px grid and 2px regular stroke match Lucide on purpose, so the two can
share an interface without clashing.
| | IconMind | Generalist sets |
|---|---|---|
| Vocabulary | AI, agents, MCP, RAG, data, devops | General UI |
| Grid | 24px, 2px stroke | Usually the same |
| Variants | 6 drawings per concept | Usually 1–2 |
| Consistency | Machine-enforced geometry | Reviewed by eye |
| For AI assistants | Built-in MCP server | — |
## The set
**5,287 icons · 20 domains · 6 cells each.** Two variants, outline and duotone, each
drawn at three weights (1.5 / 2 / 2.5). A weight is a real drawing constraint, not a
`stroke-width` slider: gap and legibility rules tighten as the stroke grows, and the
validator checks every cell separately.
Duotone is **derived, never drawn**: every closed body tints at 20% behind the strokes,
and icons made only of open marks (a check, an arrow) get a halo, the same paths echoed
wider behind them, so the whole set answers the variant switch, not just the lucky icons.

### One API, everywhere
Every framework package exposes the same component names and the same props, generated
from one source so they cannot drift:
| Prop | Default | What it does |
|---|---|---|
| `size` | `24` | Width and height |
| `color` | `currentColor` | Stroke colour |
| `variant` | `"outline"` | `"outline"` or `"duotone"` |
| `weight` | `"regular"` | `"thin"`, `"regular"` or `"bold"`, each its own drawing |
| `strokeWidth` | per weight | Fine adjustment; picking a weight redraws instead |
| `absoluteStrokeWidth` | `false` | Keeps stroke thickness constant as size changes |
The same icon in four stacks:
```tsx
// React / Preact / Solid — also Vue and Svelte with template syntax
<VectorDatabase variant="duotone" weight="bold" size={32} />
```
```dart
// Flutter — real strokes on a CustomPaint, not an icon font,
// so duotone and the weights survive intact
IconMind(IconMindIcons.vectorDatabase,
variant: IconMindVariant.duotone, weight: IconMindWeight.bold, size: 32)
```
```blade
{{-- Laravel — server-rendered, zero JavaScript --}}
<x-im-vector-database-duotone-bold class="w-8 h-8" />
```
```astro
---
import { VectorDatabase } from "@iconmind/astro";
---
<VectorDatabase variant="duotone" weight="bold" size={32} />
```
### Tree shaking, measured
Importing three icons costs ~660 bytes gzipped, not the whole library, and that is a
test that fails in CI if it stops being true rather than a promise. Every icon is also its own
entry point (`@iconmind/react/icons/agent`). In Flutter, icons are compile-time
constants: the AOT compiler drops every one you never mention.
## Download
Every icon page has a **Download** menu with SVG, PNG at 16 to 512 px, WebP, a favicon `.ico`, JPEG and *Copy PNG*, rendered in your browser from the exact variant, weight and colour on screen. The whole set ships as two archives on every [GitHub Release](https://github.com/Iconmind/iconmind/releases): `iconmind-svg.zip` (all 31,722 cells) and `iconmind-png.zip` (one 512 px PNG per icon). It is also an [Iconify](https://icones.js.org) collection (`iconmind:agent`) and one jsDelivr URL away with no install.
## For AI assistants
There is an MCP server, so an assistant writing your UI can search the real set instead
of guessing icon names that do not exist:
```bash
claude mcp add iconmind -- npx -y @iconmind/mcp
```
**shadcn/ui.** The set is also a [shadcn registry](https://ui.shadcn.com/docs/registry) item, so a shadcn project gets an `<Icon name="agent-run" />` wrapper over `@iconmind/react` in one command, no approval from anyone:
```bash
npx shadcn@latest add https://iconmind.dev/r/iconmind.json
```
It runs offline, bundles the icon data, and starts in well under a second. The site also
serves [`llms.txt`](https://iconmind.dev/llms.txt) and a full machine-readable
inventory, so assistants without tool access can still pick real names.
## No build step at all
`@iconmind/icons` ships every cell as a file on disk
(`icons/<category>/<slug>/<variant>-<weight>.svg`), a `sprite.svg` of `<symbol>`
elements, and the metadata database on its own subpath, so importing it is a decision
rather than an accident:
```html
<svg width="24" height="24"><use href="sprite.svg#im-agent" /></svg>
```
```js
import { getIcon, iconsIn } from "@iconmind/icons/metadata"; // tools only: ~180 KB gz
import { version } from "@iconmind/icons"; // a few hundred bytes
```
## Design system
Icons here are **written, not drawn**: each one is a TypeScript declaration compiled
into its six cells, and every rule a machine can hold is held by a machine. An illegal
drawing cannot reach a file, because the shape constructors throw before it does:
```
24 × 24 canvas · 0.5 grid · angles 0 / 45 / 90 only · live area 2..22
round caps · ≤ 2 stroke crossings · ink centred within 2 units
longer side 18–22 across the whole set · duotone tint 20%, halo = weight + 3
```
The vocabulary does the rest: a family shares one body and differs only in the mark
inside it, so siblings are byte-identical where they agree.
| Body | Meaning | Example |
|---|---|---|
| Open ring | An agent, acting on its own | `agent`, `agent-check` |
| Chamfered box | A machine; the chamfer is MCP's mark | `model`, `mcp-server` |
| Two-pronged plug | A capability an agent can pick up | `tool-calling`, `mcp-tool` |
| Page with a fold | A document | `mcp-resource`, `policy` |
| Squared shield | Protection | `shield-check`, `encryption` |
| Square loop | Anything that goes round | `refresh`, `retry`, `sync` |
| Cylinder | Stored data | `database`, `backup` |
So you can usually guess the next icon in a family before you see it. The full
reasoning, with the measurements behind each rule, is in the
[design guidelines](https://iconmind.dev/docs/design-guidelines/).
### Measured, not just validated
Beyond the validator, three tools keep the set honest at scale. All three grew out of
real audits that redrew more than sixty icons:
```bash
pnpm icons:audit # size, ink density and centred-ness outliers, with named exceptions
pnpm icons:twins # renders all 5,287 icons and pixel-compares every pair for lookalikes
pnpm icons:duplicates --perceptual # the nightly scan: 31,722 cells, fails on two that render alike
```
## Don't take my word for it
Every claim on this page is a command you can run after cloning:
```bash
pnpm icons:validate # every rule, all 31,722 cells
pnpm icons:twins # pixel-compare every pair at 24px
pnpm icons:duplicates --perceptual # the nightly scan for lookalikes
pnpm test # including the bundle-size tripwires
```
## Versioning & releases
All npm packages share one version (currently in lock-step with `iconmind_flutter` on
pub.dev), and releases are fully automatic: every merged change steps the patch version,
publishes all packages, tags, cuts a GitHub Release and redeploys the site. What you
see on npm is never ahead of or behind the repo.
## FAQ
**Why is there no CommonJS build?** Providing one would provide a path that does not
tree-shake well, and some bundlers would silently choose it. ESM only.
**Why only 0/45/90° angles?** It is the constraint that makes 5,287 icons read as one
hand. Some pictures are refused rather than drawn badly: a warning triangle at 45° is
a tent, so `warning` is a circle. The rest of the refusals are
[listed here](https://iconmind.dev/not-here/).
**Can I request an icon?** Yes, and it takes a minute and is the most useful contribution
there is: [request an icon](https://github.com/iconmind/iconmind/issues/new?template=icon-request.yml).
**Brand icons?** No. Concepts age better than logos, and logos carry trademark weight
this set does not want.
**Is there a Figma library?** No, and none is planned. It would be a second source of
truth beside the compiler. The set is an [Iconify](https://icones.js.org) collection
(`iconmind:agent`), which Iconify's own Figma plugin reads, and every icon page copies
or downloads its SVG.
**How do I pick between IconMind and Lucide/Tabler/Heroicons?** There are
[comparison pages](https://iconmind.dev/compare/) with the counts, licences and
trade-offs written out.
## Contributing
Icons are TypeScript declarations in `scripts/draw/icons/`. The compiler and validator
give you feedback in seconds, and a contact sheet renders any subset at 88/24/16px:
```bash
pnpm install
pnpm icons:build # draw every icon from source
pnpm icons:validate # every rule, all 31,722 cells
pnpm icons:audit # the consistency measures
```
See the [contributing guide](CONTRIBUTING.md) for naming rules, originality policy and
the pull-request checklist.
Ten icons are [described down to their body and mark slot](https://github.com/Iconmind/iconmind/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+icon%22)
if you want one to start from. The drawing is the fun part; the rules are the tools' job.
