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 that returns
real names instead of .
5,200+ open-source icons for AI-era software — agents, MCP, RAG, LLMs — with an MCP server so your coding assistant picks real names. React, Vue, Svelte, Solid, Preact, React Native, Astro, Laravel, Flutter. MIT.
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 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.

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.
AI & LLM: models, prompts, tokens, embeddings, evaluation, safety
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

"outline"
"outline" or "duotone"

"regular"
"thin", "regular" or "bold", each its own drawing

Fine adjustment; picking a weight redraws instead
absoluteStrokeWidth

Keeps stroke thickness constant as size changes
The same icon in four stacks:
// React / Preact / Solid — also Vue and Svelte with template syntax
<VectorDatabase variant="duotone" weight="bold" size={32} />
// 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)
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: iconmind-svg.zip (all 31,722 cells) and iconmind-png.zip (one 512 px PNG per icon). It is also an Iconify 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:
claude mcp add iconmind -- npx -y @iconmind/mcp
shadcn/ui. The set is also a shadcn registry item, so a shadcn project gets an <Icon name="agent-run" /> wrapper over @iconmind/react in one command, no approval from anyone:
It runs offline, bundles the icon data, and starts in well under a second. The site also
serves 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:
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.
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:
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:
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.
Can I request an icon? Yes, and it takes a minute and is the most useful contribution
there is: request an icon.
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 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 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:
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

If this set saves you from mapping reranker to a generic sort icon, a ⭐ helps other
people building AI interfaces find it.
