# Keyline Icons

Lets an agent look up an icon by name and hand back its SVG source or a React import. Useful when the name has to be guessed rather than looked up.

## What it does

The server covers three jobs: searching the set, returning full SVG source, and producing the right import from `@keyline-icons/react`. It speaks stdio, needs no API key, and never touches the network — the whole set ships inside the package.

Names are compound and read base-first. A mail icon with a tick is `mail-check`, not `check-mail`, and containers act as prefixes: `square-arrow-down`. Ranking puts an exact hit above a prefix, a prefix above a word boundary, and that above a substring, so `check` comes back before the twelve compounds built on it. Typos resolve in a single turn: substring first, then edit distance, then leading segment. `chekc` points at `check`; `arow` leads to the `arrow-*` family even though no bare `arrow` icon exists.

A missing style is an answer, not a failure. `bar-chart` is three open strokes with nothing inside, so it carries no fill, and the tool says so. Duotone and fill need a closed region — either the glyph's own enclosed area or a square or circle container. Start with `describe_set`; it returns counts, styles, and the rule that decides which icon gets which style.

## Requirements
- Needs: Node.js (commands run via npx)

## Install

### Claude Code (native platform)

**Platform CLI**
```bash
claude mcp add mcp -- npx -y @keyline-icons/mcp
```

### Codex

**Platform CLI**
```bash
codex mcp add mcp -- npx -y @keyline-icons/mcp
```

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "mcp": {
            "command": "npx",
            "args": [
                "-y",
                "@keyline-icons/mcp"
            ]
        }
    }
}
```

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "mcp": {
            "type": "stdio",
            "command": "npx",
            "args": [
                "-y",
                "@keyline-icons/mcp"
            ]
        }
    }
}
```

### Gemini CLI

**Platform CLI**
```bash
gemini mcp add mcp npx -y @keyline-icons/mcp
```

## When to use it
- find an icon from an approximate name without guessing word order
- pull SVG source for a specific style and corner treatment
- get the correct import line from `@keyline-icons/react`
- check whether an icon supports fill before building the layout
- understand the set's styles before picking icons

## Example prompts
- Find the mail icon with a tick and show its SVG in `regular`.
- Which styles does `bar-chart` have, and why is there no fill?
- Give me the import and JSX for `square-arrow-down` from `@keyline-icons/react`.
